fix readme

This adds archive links to updated Teth clients to make set up work with newserv more seamlessly. The Teth clients linked:

- Have map files for Coren
- Have fixed unitxt_e.prs and unitxt_j.prs files so no "Revival Curiass" error
- Connect to 127.0.0.1 by default for the common use case of local server on same machine
- Japanese client has had the version string changed to "JTethVer12513" so it doesn't get overriden to English

I will probably update these archives in the future to use the English files properly with the English client but for now this will make things just work in the mean time hopefully.

+The history of this project essentially mirrors my development as a software engineer from the beginning of my hobby until now. If you don't care about the story, skip to the "Compatibility" or "Setup" sections below.
+
+I originally purchased PSO GC when I heard about PSUL, and wanted to play around with running homebrew on my GameCube. This pathway eventually led to [GCARS-CS](https://github.com/fuzziqersoftware/gcars-cs), but that's another story.
+
+<img align="left" src="static/s-khyps.png" /> After playing PSO for a while, both offline and online, I wrote a proxy called Khyps sometime in 2003. This was back in the days of the official Sega servers, where vulnerabilities weren't addressed in a timely manner or at all. It was common for malicious players using their own proxies or Action Replay codes (a story for another time) to send invalid commands that the servers would blindly forward, and cause the receiving clients to crash. These crashes were more than simply inconvenient; they could also corrupt your save data, destroying the hours of work you may have put into hunting items and leveling up your character.
+
+For a while it was essentially necessary to use a proxy to go online at all, so the proxy could block these invalid commands. Khyps was designed primarily with this function in mind, though it also implemented some convenient cheats, like the ability to give yourself or other players infinite HP and allow you to teleport to different places without using an in-game teleporter.
+
+<img align="left" src="static/s-khyller.png" /> After Khyps I took on the larger challenge of writing a server, which resulted in Khyller sometime in 2005. This was the first server of any type I had ever written. This project eventually evolved into a full-featured environment supporting all versions of the game that I had access to - at the time, PC, GC, and BB. (However, I suspect from reading the ancient source files that Khyller's BB support was very buggy.) As Khyller evolved, the code became increasingly cumbersome, littered with debugging filth that I never cleaned up and odd coding patterns I had picked up over the years. My understanding of the C++ language was woefully incomplete as well (as opposed to now, when it is still incomplete but not woefully so), which resulted in Khyller being essentially a C project that had a couple of classes in it.
+
+<img align="left" src="static/s-aeon.png" /> Sometime in 2006 or 2007, I abandoned Khyller and rebuilt the entire thing from scratch, resulting in Aeon. Aeon was substantially cleaner in code than Khyller but still fairly hard to work with, and it lacked a few of the more arcane features I had originally written (for example, the ability to convert any quest into a download quest). In addition, the code still had some stability problems... it turns out that Aeon's concurrency primitives were simply incorrect. I had derived the concept of a mutex myself, before taking any real computer engineering classes, but had implemented it incorrectly. I made the race window as small as possible, but Aeon would still randomly crash after running seemingly fine for a few days.
+
+At the time of its inception, Aeon was also called newserv, and you may find some beta releases floating around the Internet with filenames like `newserv-b3.zip`. I had released betas 1, 2, and 3 before I released the entire source of beta 5 and stopped working on the project when I went to college. This was around the time when I switched from writing software primarily on Windows to primarily on macOS and Linux, so Aeon beta 5 was the last server I wrote that specifically targeted Windows. (newserv, which you're looking at now, is a bit tedious to compile on Windows but does work.)
+
+<img align="left" src="static/s-newserv.png" /> After a long hiatus from PSO and much professional and personal development in my technical abilities, I was reminiscing sometime in October 2018 by reading my old code archives. Somehow inspired when I came across Aeon, I spent a weekend and a couple more evenings rewriting the entire project again, cleaning up ancient patterns I had used eleven years ago, replacing entire modules with simple STL containers, and eliminating even more support files in favor of configuration autodetection. The code is now suitably modern and stable, and I'm not embarrassed by its existence, as I am by Aeon beta 5's source code and my archive of Khyller (which, thankfully, no one else ever saw).
+
+## Other server projects
+
+Independently of this project, there are many other PSO servers out there. Those that I know of that are (or were) public are listed here in approximate chronological order:
+
+* (Early 2000s) **[Schtserv](https://schtserv.com/)**: The first public-access PSO server; written in Delphi by Schthack. Still active and popular as of this writing (early 2024). Schtserv is also the only other unofficial server to support all versions of PSO, including Episode 3.
+* (2005) **Khyller**: An early attempt of mine to support PSO PC, GC, and BB. See above for more details.
+* (2006) **Aeon**: My second attempt. Better than Khyller, but still unreliable.
+* (2008) **Tethealla**: A fairly extensive implementation of PSOBB, written in C by Sodaboy. The public version of Tethealla has been [officially disowned](https://www.pioneer2.net/community/threads/tethealla-server-forums-removal.26365/) (as it is now more than 15 years old), but closed-source development continues. [Ephinea](https://ephinea.pioneer2.net/), currently the most popular PSOBB server, is the continuation of this project. Several other modern PSOBB servers are forks of the initial public version of Tethealla as well.
+* (2008) **[Sylverant](https://sylverant.net/)** [(source)](https://sourceforge.net/projects/sylverant/): The second public-access PSO server; written in C by BlueCrab. Still active and popular as of this writing (early 2024).
+* (2015) **[Archon](https://github.com/dcrodman/archon)**: A PSOBB server written in Go by Drew Rodman.
+* (2015) **[Idola](https://github.com/HybridEidolon/idolapsoserv)**: A PSOBB server written in Rust by HybridEidolon. Functionality status unknown; the project has been archived.
+* (2017) **[Aselia](https://github.com/Solybum/Aselia)**: A PSOBB server written written in C# by Soly. It seems this was planned to be open-source at some point, but that has not (yet) happened.
+* (2018) **newserv**: This project right here.
+* (2019) **[Mechonis](https://gitlab.com/sora3087/mechonis)**: A PSOBB server with a microservice architecture written in TypeScript by TrueVision.
+* (2021) **[Phantasmal World](https://github.com/DaanVandenBosch/phantasmal-world)**: A set of PSO tools, including a web-based model viewer and quest builder, and a PSO server, written by Daan Vanden Bosch.
+* (2021) **[Elseware](http://git.sharnoth.com/jake/elseware)**: A PSOBB server written in Rust by Jake.
+

+
+## Using newserv in other projects
+
+There is a fair amount of code in this project that could potentially be useful to other projects. You are free to use code from newserv in your own open-source projects; the only condition is that the contents of the LICENSE file must be included in your project if you use code from newserv. Your project does not also have to use the MIT license; you can use any license you want.
+
+If you want to use parts of newserv in your project, there are two easy ways to do so with proper licensing:
+* If you're using a lot of code from newserv, you can put a copy of newserv's LICENSE file in your repository alongside your own license file, or include the contents of newserv's license in your own license file.
+* If you're only using a few files from newserv, you can copy and paste the contents of the LICENSE file into a comment at the beginning of each copied file.
+
+# Compatibility
+
+newserv supports all known versions of PSO, including development prototypes. This table lists all versions that newserv supports. (NTE stands for Network Trial Edition; the GameCube beta versions were called Trial Edition instead, but we use the NTE abbreviation anyway for consistency.)

 *Notes:*
-1. *Players can create games, edit decks, trade cards, and participate in auctions, but CARD battles don't work on Episode 3 Trial Edition on newserv.*
+1. *Episode 3 NTE battles are not well-tested; some things may not work. See notes/ep3-nte-differences.txt for a list of known differences between NTE and the final version. NTE and non-NTE players cannot battle each other.*
 2. *Some BB-specific features are not well-tested (for example, some quests that use rare commands may not work properly). Please submit a GitHub issue if you find something that doesn't work.*
 3. *This is the only version of PSO that doesn't have any way to identify the player's account - there is no serial number or username. For this reason, AllowUnregisteredUsers must be enabled in config.json to support PC NTE, and PC NTE players receive a random Guild Card number every time they connect. To prevent abuse, PC NTE support can be disabled in config.json.*
 
-## Setup
+# Setup
 
-### Configuration
+## Server setup
 
 Currently newserv works on macOS, Windows, and Ubuntu Linux. It will likely work on other Linux flavors too.
 
-There is a fairly recent macOS ARM64 release on the newserv GitHub repository. You may need to install libevent manually even if you use this release (run `brew install libevent`).
+### Windows/macOS
 
-There is a fairly recent Windows release on the newserv GitHub repository also. It's built with Cygwin, and all the necessary DLL files should be included. That said, I've only tested it on my own machine and there is no CI for Windows builds like there is for macOS and Linux, so if it doesn't work for you, please open a GitHub issue to let me know.
+1. Download the latest release-windows-amd64.zip or release-macos-arm64.zip file from the [releases page](https://github.com/fuzziqersoftware/newserv/releases).
+2. Extract the contents of the archive to some location on your computer.
+3. (Optional) If you want to change any config options, go into the system/ folder, open config.json in a text editor, and edit it to your liking. There are comments in the file that describe what all the options do.
+4. (Optional) If you plan to play Blue Burst on newserv, set up the patch directory. See [client patch directories](#client-patch-directories) for details.
+5. Run the newserv executable.
 
-If you're not using a release from the GitHub repository, do this to build newserv:
-1. If you're on Windows, install Cygwin. While doing so, install the `cmake`, `gcc-core`, `gcc-g++`, `git`, `libevent2.1_7`, `make`, `libiconv-devel`, and `zlib` packages. Do the rest of these steps inside a Cygwin shell (not a Windows cmd shell or PowerShell).
-2. Make sure you have CMake, libevent, and libiconv installed. (On macOS, `brew install cmake libevent libiconv`; on most Linuxes, `sudo apt-get install cmake libevent-dev`; on Windows, you already did this in step 1.)
-3. Build and install phosg (https://github.com/fuzziqersoftware/phosg).
-4. Optionally, install resource_dasm (https://github.com/fuzziqersoftware/resource_dasm). This will enable newserv to send memory patches and load DOL files on PSO GC clients. PSO GC clients can play PSO normally on newserv without this.
+### Linux
+
+There are currently no precompiled releases for Linux. To run newserv on Linux, you'll have to build it from source - see the "Building from source" section below.
+
+### Building from source
+
+1. Install the packages newserv depends on.
+    * If you're on Windows, install [Cygwin](https://www.cygwin.com/). While doing so, install the `cmake`, `gcc-core`, `gcc-g++`, `git`, `libevent2.1_7`, `libevent-devel`, `make`, `libiconv-devel`, and `zlib` packages. Do the rest of these steps inside a Cygwin shell (not a Windows cmd shell or PowerShell).
+    * If you're on macOS, run `brew install cmake libevent libiconv`.
+    * If you're on Linux, run `sudo apt-get install cmake libevent-dev` (or use your Linux distribution's package manager).
+3. Build and install [phosg](https://github.com/fuzziqersoftware/phosg).
+4. Optionally, install [resource_dasm](https://github.com/fuzziqersoftware/resource_dasm). This will enable newserv to send memory patches and load DOL files on PSO GC clients. PSO GC clients can play PSO normally on newserv without this.
 5. Run `cmake . && make` in the newserv directory.
 
-After building newserv or downloading a release, do this to set it up and use it:
-1. In the system/ directory, make a copy of config.example.json named config.json, and edit it appropriately.
-2. If you plan to play PSO Blue Burst on newserv, set up the patch directory. See the "Client patch directories" section below.
-3. Run `./newserv` in the newserv directory. This will start the game server and run the interactive shell. You may need `sudo` if newserv's built-in DNS server is enabled.
-4. If you set AllowUnregisteredUsers to false in config.json, use the interactive shell to add your license. Run `help` in the shell to see how to do this.
-5. Set your client's network settings appropriately and start an online game. See the "Connecting local clients" or "Connecting remote clients" section to see how to get your game client to connect.
+After building newserv, edit system/config.example.json as needed **and rename it to system/config.json** (note that this step is not necessary for the precompiled releases!), set up [client patch directories](#client-patch-directories) if you're planning to play Blue Burst, then run `./newserv` in newserv's directory.
+
+The server has an interactive shell which can be used to make changes, such as managing user accounts, updating the server's configuration, managing Episode 3 tournaments, and more. Type `help` and press Enter to see all the commands.
+
+On Linux and macOS, the server also responds to SIGUSR1 and SIGUSR2. SIGUSR1 does the equivalent of the shell's `reload config` command, which reloads config.json but not any dependent files (so quests, Episode 3 maps, etc. will not be reloaded). SIGUSR2 does the equivalent of the shell's `reload all` command, which reloads everything.
 
 To use newserv in other ways (e.g. for translating data), see the end of this document.
 
-### Installing quests
+## Client patch directories
+
+newserv implements a patch server for PSO PC and PSO BB game data. Any file or directory you put in the system/patch-bb or system/patch-pc directories will be synced to clients when they connect to the patch server.
+
+For Blue Burst set up, the below is mandatory for a smooth experience:
+
+1. Browse to your chosen client's data directory.
+2. Copy all the `map_*.dat` files, `unitxt_*` files and the `data.gsl` file and place them in `system/patch-bb/data`.
+3. If you're using game files from the Tethealla client, make a copy of `unitxt_j.prs` inside system/patch-bb/data and name it `unitxt_e.prs`. (If `unitxt_e.prs` already exists, replace it with the copied file.)
+
+If you don't have a BB client, or if you're using a Tethealla client from another source, Tethealla clients that are compatible with newserv can be found here: [English](https://web.archive.org/web/20240402011115/https://ragol.org/files/bb/TethVer12513_English.zip) / [Japanese](https://web.archive.org/web/20240402013127/https://ragol.org/files/bb/TethVer12513_Japanese.zip). These clients connect to 127.0.0.1 (localhost) automatically.
+
+For BB clients, newserv reads some files out of the patch data to implement game logic, so it's important that certain game files are synchronized between the server and the client. newserv contains defaults for these files in the system/maps/bb-v4 directory, but if these don't match the client's copies of the files, odd behavior will occur in games.
+
+To make server startup faster, newserv caches the modification times, sizes, and checksums of the files in the patch directories. If the patch server appears to be misbehaving, try deleting the .metadata-cache.json file in the relevant patch directory to force newserv to recompute all the checksums. Also, in the case when checksums are cached, newserv may not actually load the data for a patch file until it's needed by a client. Therefore, modifying any part of the patch tree while newserv is running can cause clients to see an inconsistent view of it.
+
+Patch directory contents are cached in memory. If you've changed any of these files, you can run `reload patch-indexes` in the interactive shell to make the changes take effect without restarting the server.
+
+## How to connect
+
+### PSO DC
+
+Depending on the version of PSO DC that you have, the instructions to connect to a newserv instance will vary.
+
+If you have NTE, USv1, EUv1, or EUv2 and a Broadband Adapter, edit the broadband DNS address to newserv's IP address with newserv's DNS server running. Otherwise, it is necessary to patch the disc or use a codebreaker code to remove the Hunter License server check and/or redirect PSO to the newserv instance. Patching the disc or creating a codebreaker code is beyond the scope of this document.
+
+### PSO DC on Flycast
+
+If you're emulating PSO DC, the NTE, USv1, EUv1, and EUv2 versions will connect to newserv by setting the following options in Flycast's `emu.cfg` file under `[network]`:
+- DNS = Your newserv's server address (newserv's DNS server must be running on port 53)
+- EmulateBBA = yes
+- Enable = yes
+
+It is also necessary to save any DNS information to the flash memory of the Dreamcast to use the BBA - the easiest way to do this is to use the website option in USv2 and then choose the save to flash option.
+
+If the server is running on the same machine as Flycast, this might not work, even if you point Flycast's DNS queries at your local IP address (instead of 127.0.0.1). In this case, you can modify the loaded executable in memory to make it connect anywhere you want. There is a script included with newserv that can do this on macOS; a similar technique could be done manually using scanmem on Linux or Cheat Engine on Windows. To use the script, do this:
+1. Build and install [memwatch](https://github.com/fuzziqersoftware/memwatch).
+2. Start Flycast and run PSO. (You must start PSO before running the script; it won't work if you run the script before loading the game.)
+3. Run `sudo patch_flycast_memory.py <original-destination>`. Replace `<original-destination>` with the hostname that PSO wants to connect to (you can find this out by using Wireshark and looking for DNS queries). The script may take up to a minute; you can continue using Flycast while it runs, but don't start an online game until the script is done.
+4. Run newserv and start an online game in PSO.
+
+If you use this method, you'll have to run the script every time you start PSO in Flycast, but you won't have to run it again if you start another online game without restarting emulation.
+
+If using JPv1, JPv2, or USv2, it is also necessary to remove the Hunter Licence server check, either with a disc patch or codebreaker code. Patching the disc or creating a codebreaker code is beyond the scope of this document.
+
+### PSO PC
+
+PSO PC has its connection addresses in `pso.exe`. Hex edit the executable with the connection address you want to connect to. Common server addresses to search for to replace are:
+- pso20.sonic.isao.net
+- sg207634.sonicteam.com
+- pso-mp01.sonic.isao.net
+- gsproduc.ath.cx
+- sylverant.net
+
+The version of PSO PC I have has the server addresses starting at offset 0x29CB34 in pso.exe. Change those addresses to "localhost" (without quotes) if you just want to connect to a locally-running newserv instance. Alternatively, you can add an entry to the Windows hosts file (C:\Windows\System32\drivers\etc\hosts) to redirect the connection to 127.0.0.1 (localhost) or any other IP address.
+
+### PSO GC on a real GameCube
+
+You can make PSO connect to newserv by setting the default gateway and DNS server addresses in the game's network settings to newserv's address. newserv's DNS server must be running on port 53 and must be accessible to the GameCube. If you're not playing PSO Plus or Episode III, this should be all you need to do, assuming you already set LocalAddress in config.json to your PC's private IP address.
+
+If you have PSO Plus or Episode III, it won't want to connect to a server on the same local network as the GameCube itself, as determined by the GameCube's IP address and subnet mask. There are a couple of ways to get around this.
+
+Sodaboy described a fairly easy method, which is to forward the PSO and DNS ports in your router's configuration to your PC's private IP address (the PSO ports are in config.json, and are all TCP; the DNS port is 53 and is UDP). Then, set LocalAddress and ExternalAddress in config.json to your external IP address (from e.g. whatismyip.com). Most routers will let you connect to your public IP address even from within the local network, but the GameCube will think it's connecting to a different network, so it won't reject the connection. If you're concerned about security and don't want your server to be publicly accessible, you can use Windows Firewall or UFW on Linux block incoming connections on the ports you opened, except for connections from the IP addresses you specify.
+
+Another method is to use two network interfaces on the same PC, and tell the GameCube to connect to the one that appears to be on a different network. For example, if your GameCube is on the 10.0.0.x subnet and your PC's address is 10.0.0.5, you can create a fake network adapter on your PC (or use an existing real one) that has an IP address on a different subnet than the GameCube, such as 192.168.0.8. Then, in PSO's network config, set the default gateway and DNS server addresses to 192.168.0.8, and set LocalAddress in config.json to 192.168.0.8, and PSO should connect. This is what I did back in the old days when I primarily developed software on Windows, but I haven't tried it in many years.
+
+### PSO GC on a Wii or Wii U
+
+Using a Wii or Wii U to connect to newserv requires the Wii or vWii to be softmodded. How to do this is beyond the scope of this document.
+
+Nintendont includes BBA emulation and is compatible with all PSO GameCube versions except Episodes I&II Trial Edition. To use Nintendont, enable BBA emulation in Nintendont's settings and follow the instructions in the above section (PSO GC on a real GameCube).
+
+Devolution includes modem emulation and is compatible with all PSO GameCube versions including Episodes I&II Trial Edition. newserv can act as a PPP server, which Devolution can directly connect to. To do this:
+1. Enable the PPPRawListen option according to the comments in config.json.
+2. Start newserv.
+3. In the game's network settings, set the username and password to anything (they cannot be blank), and set the phone number to the number that newserv outputs to the console during startup. (It will be near the end of all the startup log messages.) If your Wii is on the same network as newserv, use the local number; otherwise, use the external number.
+
+### PSO GC on Dolphin
+
+If you're using the HLE BBA type, set the BBA's DNS server address to newserv's IP address and it should work. (If newserv is on the same machine as Dolphin, you will need to use an action replay code directed at 127.0.0.1 to connect, as PSO rejects DNS queries from the same IP address.) Set PSO's network settings the same as listed below.
+
+If you're using the TAP BBA type, you'll have to set PSO's network settings appropriately for your tap interface. Set the DNS server address in PSO's network settings to newserv's IP address.
+
+If you're using the tapserver BBA or modem type, you can make it connect to a newserv instance running on the same machine via the tapserver interface. To do this:
+1. In the GameCube pane of the Config window, set the SP1 device to Broadband Adapter (tapserver) or Modem Adapter (tapserver).
+2. Set IPStackListen (for BBA) or PPPStackListen (for modem) according to the comments in config.json and start newserv.
+3. In PSO's network settings, enable DHCP ("Automatically obtain an IP address"), set DNS server address to "Automatic", and leave DHCP Hostname as "Not set". Leave the proxy server settings blank.
+4. Start an online game.
+
+### PSO BB
+
+The PSO BB client has been modified and distributed in many different forms. newserv supports most, but not all, of the common distributions. Unlike other versions, it's important that the client and server have the same map files, so make sure to set up the patch directory based on the client you'll be using with newserv. (See the "Client patch directories" section for instructions on setting this up.)
+
+The original Japanese and US versions of PSO BB work with newserv (the last Japanese release can be found [here](https://archive.org/details/psobb_jp_setup_12511_20240109/)). To get them to connect to your server, do one of the following:
+* Use a drop-in patcher like [AzureFlare](https://github.com/Repflez/AzureFlare).
+* Modify your hosts file to redirect the client's destination address to localhost or your server's address.
+* Edit psobb.exe to point to your newserv instance. The original clients are packed with various versions of ASProtect, so this is a more involved process than simply opening the executable in a hex editor and finding/replacing some strings.
+
+Alternatively, you can use the Tethealla client ([English](https://web.archive.org/web/20240402011115/https://ragol.org/files/bb/TethVer12513_English.zip) or [Japanese](https://web.archive.org/web/20240402013127/https://ragol.org/files/bb/TethVer12513_Japanese.zip)). If the server is on the same PC as the client and you don't plan to have any external players, these Tethealla clients will automatically connect to the server without any modifications. This version of the client is not packed, and you can find the connection addresses starting at 0x56D724 in psobb.exe. Overwrite these addresses with your server's hostname or IP address, and you should be able to connect.
+
+### Connecting external clients
+
+If you want to accept connections from outside your local network, you'll need to set ExternalAddress to your public IP address in the configuration file, and you'll likely need to open some ports in your router's NAT configuration - specifically, all the TCP ports listed in PortConfiguration in config.json.
+
+For GC clients, you'll have to use newserv's built-in DNS server or set up your own DNS server as well. If you want external clients to be able to use your DNS server, you'll have to forward UDP port 53 to your newserv instance. Remote players can then connect to your server by entering your DNS server's IP address in their client's network configuration.
+
+# Server feature configuration
+
+## User accounts
+
+By default, newserv does not require users to pre-register before playing; the server will instead automatically create an account the first time each player connects. These accounts have no special permissions. You can view, create, edit, and delete user accounts in the server's shell (run `help` in the shell to see how to do this).
+
+A license is a set of credentials that a player can use to log in. There are six types of licenses:
+* *DC NTE licenses* consist of a 16-character serial number and 16-character access key.
+* *DC licenses* consist of an 8-character hex serial number and an 8-character access key.
+* *PC licenses* are the same format as DC licenses, but are used for PC v2.

 newserv supports server-side item generation on all game versions, except for the earliest DC prototypes (NTE and 11/2000). By default, the game behaves as it did on the original servers - on all versions except BB, item drops are controlled by the leader client in each game, and on BB, item drops are controlled by the server.
 
@@ -152,11 +346,11 @@ There are five different available behaviors for item drops:
 
 In the `SERVER_PRIVATE` and `SERVER_DUPLICATE` modes, there is no incentive to pick up items before another player, since other players cannot pick up the items you see dropped from boxes and enemies. However, if you pick up an item and drop it later, it can then be seen and picked up by any player.
 
-The drop mode can be changed at any time during a game with the `$dropmode` chat command. If the mode is changed after some items have already been dropped, the existing items retain their visibility (that is, they still can't be picked up by other players since they were dropped before the mode was changed). You can configure which drop modes are used by default, and which modes players are allowed to choose, in config.json. See the comments above the AllowedDropModes and DefaultDropMode keys.

+## Server-side saves
+
+newserv has the ability to save character data on the server side. For PSO BB, this is required of course, but this feature can also be used on other PSO versions.
+
+Each account has 4 BB character slots and 16 non-BB character file slots. The non-BB slots are independent of the BB slots, and can be accessed with the `$savechar <slot>` and `$loadchar <slot>` commands (slots are numbered 1 through 16). `$savechar` copies the character you're currently playing as and saves the data on the server, and `$loadchar` does the reverse, overwriting your current character with the data saved on the server. Note that you can load a character that was saved from a different version of PSO, which allows you to easily transfer characters between games. On v1 and v2, changes done by `$loadchar` will be undone if you join a game; to permanently save your changes, disconnect from the lobby after using the command.
+
+There is a third command, `$bbchar <username> <password> <slot>`, which behaves similarly to `$savechar` but writes the character data to a BB character slot in a different account instead (slots are numbered 1 through 4). This can be used to "upgrade" a character to BB from an earlier version.
+
+Exactly which data is saved and loaded depends on the game version:

 After playing a battle, you can save the record of the battle with the `$saverec` command. You can then replay the battle later by using the `$playrec` command in a lobby - this will create a spectator team and play the recording of the battle as if it were happening in realtime.

+*Everything in this section requires resource_dasm to be installed, so newserv can use the assemblers and disassemblers from its libresource_file library. If resource_dasm is not installed, newserv will still build and run, but these features will not be available.*
 
-newserv implements a patch server for PSO PC and PSO BB game data. Any file or directory you put in the system/patch-bb or system/patch-pc directories will be synced to clients when they connect to the patch server.
+You can put assembly files in the system/client-functions directory with filenames like PatchName.VERS.patch.s and they will appear in the Patches menu for clients that support client functions. Client functions are written in SH-4, PowerPC, or x86 assembly and are compiled when newserv is started. The assembly system's features are documented in the comments in system/client-functions/System/WriteMemory.ppc.s.
 
-To make server startup faster, newserv caches the modification times, sizes, and checksums of the files in the patch directories. If the patch server appears to be misbehaving, try deleting the .metadata-cache.json file in the relevant patch directory to force newserv to recompute all the checksums. Also, in the case when checksums are cached, newserv may not actually load the data for a patch file until it's needed by a client. Therefore, modifying any part of the patch tree while newserv is running can cause clients to see an inconsistent view of it.
+The VERS token in client function filenames refers to the specific version of the game that the client function applies to. Some versions do not support receiving client functions at all. *Note: newserv uses the shorter GameCube versioning convention, where discs labeled DOL-XXXX-0-0Y are version 1.Y. The PSO community seems to use the convention 1.0Y in some places instead, but these are the same version. For example, the version that newserv calls v1.4 is the same as v1.04, and is labeled DOL-GPOJ-0-04 on the underside of the disc.*
 
-For BB clients, newserv reads some files out of the patch data to implement game logic, so it's important that certain game files are synchronized between the server and the client. newserv contains defaults for these files in the system/blueburst/map directory, but if these don't match the client's copies of the files, odd behavior will occur in games.
+The specific versions are:
 
-Specifically, the patch-bb directory should contain at least the data.gsl file and all map_*.dat files from the version of PSOBB that you want to play on newserv. You can copy these files out of the client's data directory from a clean installation, and put them in system/patch-bb/data.

+## Chat commands
 
 newserv supports a variety of commands players can use by chatting in-game. Any chat message that begins with `$` is treated as a chat command. (If you actually want to send a chat message starting with `$`, type `$$` instead.) On the DC 11/2000 prototype, `@` is used instead of `$` for all chat commands, since `$` does not appear on the English virtual keyboard.

When debug is enabled, you'll see in-game messages from the server when you take certain actions. You'll also be placed into the highest available slot in lobbies and games instead of the lowest, which is useful for finding commands for which newserv doesn't handle client IDs properly. This setting also disables certain safeguards and allows you to do some things that might crash your client.
-    * `$quest <number>`: Load a quest by quest number. Can be used to load battle or challenge quests with only one player present.
+    * `$debug` (game server only): Enable or disable debug. You need the DEBUG flag in your user account to use this command. Enabling debug does several things:
+        * You'll see in-game messages from the server when you take certain actions, like killing an enemy in BB.
+        * You'll see the rare seed value and floor variations when you join a game.
+        * You'll be placed into the last available slot in lobbies and games instead of the first, unless you're joining a BB solo-mode game.
+        * You'll be able to join games with any PSO version, not only those for which crossplay is normally supported. Be prepared for client crashes and other client-side brokenness if you do this. Do not submit any issues for broken behaviors in crossplay, unless the situation is explicitly supported (see the "Cross-version play" section above).
+        * The rest of the commands in this section are enabled on the game server. (They are always enabled on the proxy server.)
+    * `$quest <number>` (game server only): Load a quest by quest number. Can be used to load battle or challenge quests with only one player present. Debug is not required to be enabled if the specified quest has the AllowStartFromChatCommand field set in its metadata file.
     * `$qcall <function-id>`: Call a quest function on your client.
-    * `$qcheck <flag-num>`: Show the value of a quest flag.
-    * `$qset <flag-num>` or `$qclear <flag-num>`: Set or clear a global quest flag for everyone in the game.
-    * `$qsync <reg-num> <value>`: Set a quest register's value on your client. `<reg-num>` should be either rXX (e.g. r60) or fXX (e.g. f60); if the latter, `<value>` is parsed as a floating-point value instead of as an integer.
+    * `$qcheck <flag-num>` (game server only): Show the value of a quest flag. This command can be used without debug mode enabled. If you're in a game, show the value of the flag in that game; if you're in the lobby, show the saved value of that quest flag for your character (BB only).
+    * `$qset <flag-num>` or `$qclear <flag-num>`: Set or clear a quest flag for everyone in the game. If you're in the lobby and on BB, set or clear the saved value of a quest flag in your character file.
+    * `$qgread <flag-num>` (game server only): Show the value of a quest counter ("global flag"). This command can be used without debug mode enabled.
+    * `$qgwrite <flag-num> <value>` (game server only): Set the value of a quest counter ("global flag") for yourself.
+    * `$qsync <reg-num> <value>`: Set a quest register's value for yourself only. `<reg-num>` should be either rXX (e.g. r60) or fXX (e.g. f60); if the latter, `<value>` is parsed as a floating-point value instead of as an integer.
+    * `$qsyncall <reg-num> <value>`: Set a quest register's value for everyone in the game. `<reg-num>` should be either rXX (e.g. r60) or fXX (e.g. f60); if the latter, `<value>` is parsed as a floating-point value instead of as an integer.
+    * `$swset [floor] <flag-num>` and `$swclear [floor] <flag-num>`: Set or clear a switch flag. If floor is not given, sets or clears the flag on your current floor.
+    * `$swsetall`: Set all switch flags on your current floor. This unlocks all doors, disables all laser fences, triggers all light/poison switches, etc.
     * `$gc` (game server only): Send your own Guild Card to yourself.
-    * `$persist` (game server only): Enable or disable persistence for the current game. When persistence is on, the game will not be deleted when the last player leaves. The state of enemies and objects on the map will be reset when the last player leaves.
     * `$sc <data>`: Send a command to yourself.
-    * `$ss <data>` (proxy server only): Send a command to the remote server.
+    * `$ss <data>`: Send a command to the remote server (if in a proxy session) or to the game server.
+    * `$sb <data>`: Send a command to yourself, and to the remote server or game server.
+    * `$meseta <amount>` (game server only; Episode 3 only): Add the given amount to your Meseta total.
+    * `$auction` (Episode 3 only): Bring up the CARD Auction menu, regardless of how many players are in the game or if you have a VIP card.
+    * `$ep3battledebug` (game server only; Episode 3 only): Enable or disable TCard00_Select. If enabled, the game will enter the debug menu when you start a battle.
 
 * Personal state commands
-    * `$arrow <color-id>`: Changes your lobby arrow color.
-    * `$secid <section-id>`: Sets your override section ID. After running this command, any games you create will use your override section ID for rare drops instead of your character's actual section ID. To revert to your actual section id, run `$secid` with no name after it. On the proxy server, this will not work if the remote server controls item drops (e.g. on BB, or on Schtserv with server drops enabled). If the server does not allow cheat mode anywhere (that is, "CheatModeBehavior" is "Off" in config.json), this command does nothing.
-    * `$rand <seed>`: Sets your override random seed (specified as a 32-bit hex value). This will make any games you create use the given seed for rare enemies. This also makes item drops deterministic in Blue Burst games hosted by newserv. On the proxy server, this command can cause desyncs with other players in the same game, since they will not see the overridden random seed. To remove the override, run `$rand` with no arguments. If the server does not allow cheat mode anywhere (that is, "CheatModeBehavior" is "Off" in config.json), this command does nothing.
-    * `$ln [name-or-type]`: Sets the lobby number. Visible only to you. This command exists because some non-lobby maps can be loaded as lobbies with invalid lobby numbers. See the "GC lobby types" and "Ep3 lobby types" entries in the information menu for acceptable values here. Note that non-lobby maps do not have a lobby counter, so there's no way to exit the lobby without using either `$ln` again or `$exit`. On the game server, `$ln` reloads the lobby immediately; on the proxy server, it doesn't take effect until you load another lobby yourself (which means you'll like have to use `$exit` to escape). Run this command with no argument to return to the default lobby.
-    * `$exit`: If you're in a lobby, sends you to the main menu (which ends your proxy session, if you're in one). If you're in a game or spectator team, sends you to the lobby (but does not end your proxy session if you're in one). Does nothing if you're in a non-Episode 3 game and no quest is in progress.
+    * `$arrow <color-id>`: Change your lobby arrow color.
+    * `$secid <section-id>`: Set your override section ID. After running this command, any games you create will use your override section ID for rare drops instead of your character's actual section ID. If you're in a game and you are the leader of the game, this also immediately changes the item tables used by the server when creating items. To revert to your actual section id, run `$secid` with no name after it. On the proxy server, this will not work if the remote server controls item drops (e.g. on BB, or on Schtserv with server drops enabled). If the server does not allow cheat mode anywhere (that is, "CheatModeBehavior" is "Off" in config.json), this command does nothing.
+    * `$battle` (game server only; DC v1 only): After using this command, the next game you create will be in battle mode. (A chat command is required for this because DCv1 doesn't allow this natively.) On DCv1, the battle quests are not available, but free-roam is.
+    * `$rand <seed>`: Set your override random seed (specified as a 32-bit hex value). This will make any games you create use the given seed for rare enemies. This also makes item drops deterministic in Blue Burst games hosted by newserv. On the proxy server, this command can cause desyncs with other players in the same game, since they will not see the overridden random seed. To remove the override, run `$rand` with no arguments. If the server does not allow cheat mode anywhere (that is, "CheatModeBehavior" is "Off" in config.json), this command does nothing.
+    * `$ln [name-or-type]`: Set the lobby number. Visible only to you. This command exists because some non-lobby maps can be loaded as lobbies with invalid lobby numbers. See the "GC lobby types" and "Ep3 lobby types" entries in the information menu for acceptable values here. Note that non-lobby maps do not have a lobby counter, so there's no way to exit the lobby without using either `$ln` again or `$exit`. On the game server, `$ln` reloads the lobby immediately; on the proxy server, it doesn't take effect until you load another lobby yourself (which means you'll like have to use `$exit` to escape). Run this command with no argument to return to the default lobby.
+    * `$swa`: Enable or disable switch assist. When enabled, the server will unlock two-player and four-player doors in non-quest games when you step on any of the required switches.
+    * `$exit`: If you're in a lobby, send you to the main menu (which ends your proxy session, if you're in one). If you're in a game or spectator team, send you to the lobby (but does not end your proxy session if you're in one). Does nothing if you're in a non-Episode 3 game and no quest is in progress.
     * `$patch <name>`: Run a patch on your client. `<name>` must exactly match the name of a patch on the server.
 
-* Character data commands
-    * `$savechar <slot>`: Saves your current character data on the server in the specified slot (each serial number has 4 slots, numbered 1-4). These slots are separate from BB character slots; using this command does not affect BB characters.
-    * `$loadchar <slot>` (v1 and v2 only): Loads your character data from the specified slot. The changes will be undone if you join a game - to save your changes, disconnect from the lobby.
-    * `$bbchar <username> <password> <slot>`: Use this command when playing on a non-BB version of PSO. If the username and password are correct, this command converts your current character to BB format and saves it on the server in the given slot (1-4). Any character already in that slot is overwritten. (This command is similar to `$savechar`, except it overwrites a BB character slot, and can transfer characters across accounts.) Note that the character's chat data, quick menu config, and bank contents are not copied, since there is no way for the server to request those types of data.
-    * `$edit <stat> <value>`: Modifies your character data. If you are on V3 (GameCube/Xbox), or if the server does not allow cheat mode anywhere (that is, "CheatModeBehavior" is "Off" in config.json), this command does nothing. If you are on V1 or V2 (DC or PC, not BB), your changes will be undone if you join a game - to save your changes, disconnect from the lobby.
+* Character data commands (game server only)
+    * `$savechar <slot>`: Save your current character data on the server in the specified slot. See the "Server-side saves" section for more details.
+    * `$loadchar <slot>`: Save your current character data on the server in the specified slot. See the "Server-side saves" section for more details.
+    * `$bbchar <username> <password> <slot>`: Save your current character data on the server in a different account's BB character slots. See the "Server-side saves" section for more details.
+    * `$edit <stat> <value>`: Modify your character data. See "Using $edit" below for details.
 
 * Blue Burst player commands (game server only)
-    * `$bank [number]`: Switches your current bank, so you can access your other character's banks (if `number` is 1-4) or your shared account bank (if `number` is 0). If `number` is not given, switches back to your current character's bank.
-    * `$save`: Saves your character, system, and Guild Card data immediately. (By default, your character is saved every 60 seconds while online, and your account and Guild Card data are saved whenever they change.)
+    * `$bank [number]`: Switch your current bank, so you can access your other character's banks (if `number` is 1-4) or your shared account bank (if `number` is 0). If `number` is not given, switch back to your current character's bank.
+    * `$save`: Save your character, system, and Guild Card data immediately. (By default, your character is saved every 60 seconds while online, and your account and Guild Card data are saved whenever they change.)
 
 * Game state commands (game server only)
-    * `$maxlevel <level>`: Sets the maximum level for players to join the current game. (This only applies when joining; if a player joins and then levels up past this level during the game, they are not kicked out, but won't be able to rejoin if they leave.)
-    * `$minlevel <level>`: Sets the minimum level for players to join the current game.
-    * `$password <password>`: Sets the game's join password. To unlock the game, run `$password` with nothing after it.
-    * `$dropmode [mode]`: Changes the way item drops behave in the current game. `mode` can be `none`, `client`, `shared`, `private`, or `duplicate`. If `mode` is not given, tells you the current drop mode without changing it. See the "Item tables and drop modes" section for more information.
+    * `$maxlevel <level>`: Set the maximum level for players to join the current game. (This only applies when joining; if a player joins and then levels up past this level during the game, they are not kicked out, but won't be able to rejoin if they leave.)
+    * `$minlevel <level>`: Set the minimum level for players to join the current game.
+    * `$password <password>`: Set the game's join password. To unlock the game, run `$password` with nothing after it.
+    * `$dropmode [mode]`: Change the way item drops behave in the current game. `mode` can be `none`, `client`, `shared`, `private`, or `duplicate`. If `mode` is not given, tells you the current drop mode without changing it. See the "Item tables and drop modes" section for more information.
+    * `$persist`: Enable or disable persistence for the current game. When persistence is on, the game will not be deleted when the last player leaves. The states of enemies, objects, and switches will be saved, and items left on the floor will not be deleted. (But if you're in the private or duplicate drop mode, items dropped by enemies are deleted - to make sure a certain item won't be deleted, you can pick it up and drop it again.) If the game is empty for too long (15 minutes by default), it is then deleted.
 
 * Episode 3 commands (game server only)
-    * `$spec`: Toggles the allow spectators flag for Episode 3 games. If any players are spectating when this flag is disabled, they will be sent back to the lobby.
-    * `$inftime`: Toggles infinite-time mode. Must be used before starting a battle. If infinite-time mode is enabled, the overall and per-phase time limits will be disabled regardless of the values chosen during battle setup. After completing a battle, infinite-time mode is reset to the server's default value (which can be set in Episode3BehaviorFlags in config.json).
-    * `$defrange <min>-<max>`: Sets the DEF dice range for the next battle. If this is used, the dice range set during battle rules setup will apply only to ATK dice; DEF dice will use this range instead. Assist cards and other dice effects will still apply. Dice exchange also still applies if it is enabled.
-    * `$stat <what>`: Shows a statistic about your player or team in the current battle. `<what>` can be `duration`, `fcs-destroyed`, `cards-destroyed`, `damage-given`, `damage-taken`, `opp-cards-destroyed`, `own-cards-destroyed`, `move-distance`, `cards-set`, `fcs-set`, `attack-actions-set`, `techs-set`, `assists-set`, `defenses-self`, `defenses-ally`, `cards-drawn`, `max-attack-damage`, `max-combo`, `attacks-given`, `attacks-taken`, `sc-damage`, `damage-defended`, or `rank`.
-    * `$surrender`: Causes your team to immediately lose the current battle.
-    * `$saverec <name>`: Saves the recording of the last battle.
-    * `$playrec <name>`: Plays a battle recording. This command creates a spectator team and replays the specified battle log within it. There is a bug in Dolphin that makes use of this command unstable in emulation (see the "Battle records" section above).
+    * `$spec`: Toggle the allow spectators flag for Episode 3 games. If any players are spectating when this flag is disabled, they are sent back to the lobby.
+    * `$inftime`: Toggle infinite-time mode. Must be used before starting a battle. If infinite-time mode is on, the overall and per-phase time limits will be disabled regardless of the values chosen during battle rules setup. After completing a battle, infinite-time mode is reset to the server's default value (which can be set in Episode3BehaviorFlags in config.json).
+    * `$dicerange [d:L-H] [1:L-H] [a1:L-H] [d1:L-H]`: Set override dice ranges for the next battle. The min and max dice values from the rules setup menu always apply to the ATK dice, but you can specify a different range for the DEF dice with `d:2-4` (for example). The `1:` override applies to the 1-player team in a 2v1 game (so you would set the 2-player team's desired dice range in the rules menu). You can also specify the 1-player team's ATK and DEF ranges separately with the `a1:` and `d1:` overrides. Note that these ranges will only be used if the chosen map or quest does not override them.
+    * `$stat <what>`: Show a statistic about your player or team in the current battle. `<what>` can be `duration`, `fcs-destroyed`, `cards-destroyed`, `damage-given`, `damage-taken`, `opp-cards-destroyed`, `own-cards-destroyed`, `move-distance`, `cards-set`, `fcs-set`, `attack-actions-set`, `techs-set`, `assists-set`, `defenses-self`, `defenses-ally`, `cards-drawn`, `max-attack-damage`, `max-combo`, `attacks-given`, `attacks-taken`, `sc-damage`, `damage-defended`, or `rank`.
+    * `$surrender`: Cause your team to immediately lose the current battle. If your story character is already defeated, you can't surrender - only your teammate can.
+    * `$saverec <name>`: Save the recording of the last battle.
+    * `$playrec <name>`: Play a battle recording. This command creates a spectator team immediately but the replay does not start automatically, to give other players a chance to join. To start the battle replay within the spectator team, run `$playrec` again (with no name). There is a bug in Dolphin that makes this command unstable in emulation (see the "Battle records" section above).
 
 * Cheat mode commands
-    * `$cheat`: Enables or disables cheat mode for the current game. All other cheat mode commands do nothing if cheat mode is disabled. By default, cheat mode is off in new games but can be enabled; there is an option in config.json that allows you to disable cheat mode entirely, or set it to on by default in new games.
-    * `$infhp` / `$inftp`: Enables or disables infinite HP or TP mode. Applies to only you. In infinite HP mode, one-hit KO attacks will still kill you.
-    * `$warpme <floor-id>`: Warps yourself to the given floor.
-    * `$warpall <floor-id>`: Warps everyone in the game to the given floor. You must be the leader to use this command, unless you're on the proxy server.
-    * `$next`: Warps yourself to the next floor.
-    * `$swa`: Enables or disables switch assist. When enabled, the server will attempt to automatically unlock two-player doors in solo games if you step on both switches sequentially.
+    * `$cheat` (game server only): Enable or disable cheat mode for the current game. All other cheat mode commands do nothing if cheat mode is disabled. By default, cheat mode is off in new games but can be enabled; there is an option in config.json that allows you to disable cheat mode entirely, or set it to on by default in new games. Cheat mode is always enabled on the proxy server, unless cheat mode is disabled on the entire server.
+    * `$infhp`: Enable or disable infinite HP mode. Applies to only you; does not affect other players. When enabled, one-hit KO attacks will still kill you, but on most versions of the game (not DCv1, GC US 1.2, or GC JP 1.5), the server will automatically revive you if you die. On all versions except GC US 1.2 and GC JP 1.5, infinite HP also automatically cures status ailments.
+    * `$inftp`: Enable or disable infinite TP mode. Applies to only you; does not affect other players.
+    * `$warpme <floor-id>` (or `$warp <floor-id>`): Warp yourself to the given floor.
+    * `$warpall <floor-id>`: Warp everyone in the game to the given floor. You must be the leader to use this command, unless you're on the proxy server.
+    * `$next`: Warp yourself to the next floor.
     * `$item <desc>` (or `$i <desc>`): Create an item. `desc` may be a description of the item (e.g. "Hell Saber +5 0/10/25/0/10") or a string of hex data specifying the item code. Item codes are 16 hex bytes; at least 2 bytes must be specified, and all unspecified bytes are zeroes. If you are on the proxy server, you must not be using Blue Burst for this command to work. On the game server, this command works for all versions.
-    * `$unset <index>`: In an Episode 3 battle, removes one of your set cards from the field. `<index>` is the index of the set card as it appears on your screen - 1 is the card next to your SC's icon, 2 is the card to the right of 1, etc. This does not cause a Hunters-side SC to lose HP, as they normally do when their items are destroyed.
+    * `$unset <index>` (game server only): In an Episode 3 battle, removes one of your set cards from the field. `<index>` is the index of the set card as it appears on your screen - 1 is the card next to your SC's icon, 2 is the card to the right of 1, etc. This does not cause a Hunters-side SC to lose HP, as they normally do when their items are destroyed.
+    * `$dropmode [mode]` (proxy server): Change the way item drops behave in the current game, if you are not on BB. Unlike the game server version of this command, using this on the proxy server requires cheats to be enabled. This works by intercepting the drop requests sent to and from the leader. (So, if you are the leader and not using server drop mode on the remote server, it affects the entire game; otherwise, it affects only items generated by your actions.) `mode` can be `none` (no drops), `default` (normal drops), or `proxy` (use newserv's drop tables instead of the remote server's). If `mode` is not given, tells you the current drop mode without changing it.
 
-* Configuration commands
-    * `$event <event>`: Sets the current holiday event in the current lobby. Holiday events are documented in the "Using $event" item in the information menu. If you're on the proxy server, this applies to all lobbies and games you join, but only you will see the new event - other players will not.
-    * `$allevent <event>` (game server only): Sets the current holiday event in all lobbies.
-    * `$song <song-id>` (Episode 3 only): Plays a specific song in the current lobby.
+* Aesthetic commands
+    * `$event <event>`: Set the current holiday event in the current lobby. Holiday events are documented in the "Using $event" item in the information menu. If you're on the proxy server, this applies to all lobbies and games you join, but only you will see the new event - other players will not.
+    * `$allevent <event>` (game server only): Set the current holiday event in all lobbies.
+    * `$song <song-id>` (Episode 3 only): Play a specific song in the current lobby.
 
 * Administration commands (game server only)
-    * `$ann <message>`: Sends an announcement message. The message text is sent to all players in all games and lobbies.
-    * `$ax <message>`: Sends a message to the server's terminal. This cannot be used to run server shell commands; it only prints text to stderr.
-    * `$silence <identifier>`: Silences a player (remove their ability to chat) or unsilences a player. The identifier may be the player's name or Guild Card number.
-    * `$kick <identifier>`: Disconnects a player. The identifier may be the player's name or Guild Card number.
-    * `$ban <identifier>`: Bans a player. The identifier may be the player's name or Guild Card number.
+    * `$ann <message>`: Send an announcement message. The message is sent as temporary on-screen text to all players in all games and lobbies. On BB, the message appears in the scrolling top bar.
+    * `$ann!`, `$ann?`, `$ann?!`: Same as `$ann`, but with `?`, omits the sender's name, and with `!`, sends the message as a Simple Mail message instead of on-screen text.
+    * `$ax <message>`: Send a message to the server's terminal. This cannot be used to run server shell commands; it only prints text to stderr.
+    * `$silence <identifier>`: Silence a player (remove their ability to chat) or unsilence a player. The identifier may be the player's name or Guild Card number.
+    * `$kick <identifier>`: Disconnect a player. The identifier may be the player's name or Guild Card number.
+    * `$ban <duration> <identifier>`: Ban a player. The duration should be of the form `10m` (minutes), `10h` (hours), `10d` (days), `10w` (weeks), `10M` (months), or `10y` (years). (Numbers other than 10 may be used, of course.) As with `$kick`, the identifier may be the player's name or Guild Card number.
 
-### Connecting local clients
+### Using $edit
 
-#### PSO DC
+The $edit command modifies your character data. This command doesn't work on V3 (GameCube/Xbox). If you are on V1 or V2 (DC or PC, not BB), your changes will be undone if you join a game - to save your changes, disconnect from the lobby.
 
-Some versions of PSO DC will connect to a private server if you just set their DNS server address (in the network configuration) to newserv's address, and enable newserv's DNS server. This will not work for other versions; for those, you'll need a cheat code. Creating such a code is beyond the scope of this document.
+Some subcommands are always available. They are:
+* `$edit mat reset power`: Clear your usage of power materials (BB only)
+* `$edit mat reset mind`: Clear your usage of mind materials (BB only)
+* `$edit mat reset evade`: Clear your usage of evade materials (BB only)
+* `$edit mat reset def`: Clear your usage of def materials (BB only)
+* `$edit mat reset luck`: Clear your usage of luck materials (BB only)
+* `$edit mat reset hp`: Clear your usage of HP materials (BB only)
+* `$edit mat reset tp`: Clear your usage of TP materials (BB only)
+* `$edit mat reset all`: Clear your usage of all materials except HP and TP (BB only)
+* `$edit mat reset every`: Clear your usage of all materials including HP and TP (BB only)
+* `$edit namecolor AARRGGBB`: Set your name color (AARRGGBB specified in hex)
+* `$edit language L`: Set your language (Generally only useful on BB; values for L: J = Japanese, E = English, G = German, F = French, S = Spanish, B = Simplified Chinese, T = Traditional Chinese, K = Korean)
+* `$edit name NAME`: Set your character name
+* `$edit npc NPC-NAME`: Set or remove an NPC skin on your character (use `none` to remove a skin). The NPC names are:
+    * On all versions except DCv1 and early prototypes: `ninja`, `rico`, `sonic`, `knuckles`, `tails`
+    * On GC, Xbox, and BB: `flowen`, `elly`
+    * On BB only: `momoka`, `irene`, `guild`, `nurse`
+* `$edit secid SECID-NAME`: Set your section ID (cheat mode is required for this unless your character is Level 1)
 
-If you're emulating PSO DC or have a disc image, you can patch the appropriate files within the disc image to make it connect to any address you want. Creating such a patch is also beyond the scope of this document.
+The remaining subcommands are only available if cheat mode is enabled on the server. They are:
+* `$edit atp N`: Set your ATP to N until stats are updated (e.g. by leveling up)
+* `$edit mst N`: Set your MST to N until stats are updated
+* `$edit evp N`: Set your EVP to N until stats are updated
+* `$edit dfp N`: Set your DFP to N until stats are updated
+* `$edit ata N`: Set your ATA to N until stats are updated

-#### PSO DC on Flycast
+# Non-server features
 
-If you're emulating PSO DC, all versions will connect to newserv by setting the following options in Flycast's `emu.cfg` file under `[network]`:
-- DNS = Your newserv's server address (newserv's DNS server must be running on port 53)
-- EmulateBBA = yes
-- Enable = yes
+newserv has many CLI options, which can be used to access functionality other than the game and proxy server. Run `newserv help` to see a full list of the options and how to use each one.
 
-It is also necessary to save any DNS information to the flash memory of the Dreamcast to use the BBA - the easiest way to do this is to use the website option in USv2 and then choose the save to flash option.
+The data formats that newserv can convert to/from are:
 
-Once set up, the EU and US versions will work without any extra set up (other than the HL Check Disable code for USv2), while the JP versions require HL Check Disable codes to be running.

-If the server is running on the same machine as Flycast, this might not work, even if you point Flycast's DNS queries at your local IP address (instead of 127.0.0.1). In this case, you can modify the loaded executable in memory to make it connect anywhere you want. There is a script included with newserv that can do this on macOS; a similar technique could be done manually using scanmem on Linux or Cheat Engine on Windows. To use the script, do this:
-1. Build and install memwatch (https://github.com/fuzziqersoftware/memwatch).
-2. Start Flycast and run PSO. (You must start PSO before running the script; it won't work if you run the script before loading the game.)
-3. Run `sudo patch_flycast_memory.py <original-destination>`. Replace `<original-destination>` with the hostname that PSO wants to connect to (you can find this out by using Wireshark and looking for DNS queries). The script may take up to a minute; you can continue using Flycast while it runs, but don't start an online game until the script is done.
-4. Run newserv and start an online game in PSO.
+There are several actions that don't fit well into the table above, which let you do other things:
 
-If you use this method, you'll have to run the script every time you start PSO in Flycast, but you won't have to run it again if you start another online game without restarting emulation.
-
-#### PSO PC
-
-The version of PSO PC I have has the server addresses starting at offset 0x29CB34 in pso.exe. Using a hex editor, change those to "localhost" (without quotes) if you just want to connect to a locally-running newserv instance. Alternatively, you can add an entry to the Windows hosts file (C:\Windows\System32\drivers\etc\hosts) to redirect the connection to 127.0.0.1 (localhost) or any other IP address.
-
-#### PSO GC on a real GameCube
-
-You can make PSO connect to newserv by setting its default gateway and DNS server addresses to newserv's address. newserv's DNS server must be running on port 53 and must be accessible to the GameCube.
-
-If you have PSO Plus or Episode III, it won't want to connect to a server on the same local network as the GameCube itself, as determined by the GameCube's IP address and subnet mask. In the old days, one way to get around this was to create a fake network adapter on the server (or use an existing real one) that has an IP address on a different subnet, tell the GameCube that the server is the default gateway (as above), and have the server reply to the DNS request with its non-local IP address. To do this with newserv, just set LocalAddress in the config file to a different interface. For example, if the GameCube is on the 192.168.0.x network and your other adapter has address 10.0.1.6, set newserv's LocalAddress to 10.0.1.6 and set PSO's DNS server and default gateway addresses to the server's 192.168.0.x address. This may not work on modern systems or on non-Windows machines - I haven't tested it in many years.
-
-#### PSO GC on Dolphin
-
-If you're using the HLE BBA type, set the BBA's DNS server address to newserv's IP address and it should work. (If newserv is on the same machine as Dolphin, try your local IP address or 127.0.0.1.) In PSO, use the example values below in PSO's network configuration.
-
-If you're using the TAP BBA type, you'll have to set PSO's network settings appropriately for your tap interface. Set the DNS server address in PSO's network settings to newserv's IP address.
-
-If you're using a version of Dolphin with tapserver support, you can make it connect to a newserv instance running on the same machine via the tapserver interface. You do not need to install or run tapserver. To do this:
-1. Set Dolphin's BBA type to tapserver (Config -> GameCube -> SP1).
-2. Enable newserv's IP stack simulator according to the comments in config.json and start newserv.
-3. In PSO's network settings, enable DHCP ("Automatically obtain an IP address"), set DNS server address to "Automatic", and leave DHCP Hostname as "Not set". Leave the proxy server settings blank.
-4. Start an online game.
-
-#### PSO BB
-
-The PSO BB client has been modified and distributed in many different forms. newserv supports most, but not all, of the common distributions. Unlike other versions, it's important that the client and server have the same map files, so make sure to set up the patch directory based on the client you'll be using with newserv. (See the "Client patch directories" section for instructions on setting this up.)
-
-The original Japanese and US versions of PSO BB should work, but you'll have to modify your hosts file or edit psobb.exe to point to your newserv instance. The original versions are packed, so this is a more involved process than simply opening the executable in a hex editor and finding/replacing some strings.
-
-Alternatively, you can use the Tethealla client (https://archive.org/details/psobb-tethealla-client); you can find the connection addresses starting at 0x56D724 in psobb.exe. Overwrite these addresses with your server's hostname or IP address, and you should be able to connect.
-
-### Connecting external clients
-
-If you want to accept connections from outside your local network, you'll need to set ExternalAddress to your public IP address in the configuration file, and you'll likely need to open some ports in your router's NAT configuration - specifically, all the TCP ports listed in PortConfiguration in config.json.
-
-For GC clients, you'll have to use newserv's built-in DNS server or set up your own DNS server as well. If you want external clients to be able to use your DNS server, you'll have to forward UDP port 53 to your newserv instance. Remote players can then connect to your server by entering your DNS server's IP address in their client's network configuration.
-
-### Non-server features
-
-newserv has many CLI options, which can be used to access functionality other than the game and proxy server. Run `newserv help` to see these options and how to use them. The non-server things newserv can do are:
-
-* Compress or decompress data in PRS, PR2, or BC0 format (`compress-prs`, `compress-pr2`, `compress-bc0`, `decompress-prs`, `decompress-pr2`, `decompress-bc0`)
 * Compute the decompressed size of compressed PRS data without decompressing it (`prs-size`)
-* Encrypt or decrypt data using any PSO version's network encryption scheme (`encrypt-data`, `decrypt-data`)
-* Encrypt or decrypt data using Episode 3's trivial scheme (`encrypt-trivial-data`, `decrypt-trivial-data`)
-* Encrypt or decrypt data using the Challenge Mode text algorithm (`encrypt-challenge-data`, `decrypt-challenge-data`)
-* Encrypt or decrypt PSO GC save data (.gci files) (`encrypt-gci-save`, `decrypt-gci-save`)
-* Convert a PSO GC or Episode 3 snapshot file to a BMP image (`decode-gci-snapshot`)
 * Find the likely round1 or round2 seed for a corrupt save file (`salvage-gci`)
 * Run a brute-force search for a decryption seed (`find-decryption-seed`)
-* Convert quests in .gci, .vms, .dlq, or .qst format to .bin/.dat format (`decode-gci`, `decode-vms`, `decode-dlq`, `decode-qst`)
-* Convert quests in .bin/.dat to .qst format (`encode-qst`)
-* Convert text archives (e.g. TextEnglish.pr2) to JSON and vice versa (`decode-text-archive`, `encode-text-archive`)
-* Compile or disassemble quest scripts (`assemble-quest-script`, `disassemble-quest-script`)
-* Format Episode 3 game data in a human-readable manner (`show-ep3-maps`, `show-ep3-cards`)
-* Convert item data to a human-readable description, or vice versa (`describe-item`, `encode-item`)
+* Format Episode 3 game data in a human-readable manner (`show-ep3-maps`, `show-ep3-cards`, `generate-ep3-cards-html`)
+* Format Blue Burst battle parameter files in a human-readable manner (`show-battle-params`)
+* Search for rare enemy seeds that result in rare enemies on console versions (`find-rare-enemy-seeds`)
+* Convert item data to a human-readable description, or vice versa (`describe-item`)
 * Connect to another PSO server and pretend to be a client (`cat-client`)
-* Replay a session log for testing (`replay-log`)
-* Extract the contents of a .gsl or .bml archive (`extract-gsl`, `extract-bml`)
+* Generate or describe DC serial numbers (`generate-dc-serial-number`, `inspect-dc-serial-number`)
+
+# Docker
+Docker is new and mostly unsupported at this time. However, here are some best-effort steps to build and run in a docker container on Ubuntu Linux.
+Tested on Ubuntu 22.04.4 LTS.
+Note: You cannot have anything except this docker container using port 53 (DNS) on your server.
+
+Install prerequisites
+```
+sudo apt install -y git
+sudo apt install -y cmake. ## minimum version is 3.10. Check installed version with "cmake --version"
+```
+
+Clone repository
+```
+cd ~
+git clone https://github.com/fuzziqersoftware/newserv/
+cd ~/newserv
+```
+
+Build newserv. This will take a while. Don't forget the period at the end!
+```
+sudo docker build -t newserv .
+```
+
+Create persistent directories. Assuming you want to store the persistent data in your home directory
+```
+mkdir ~/newservPersist
+mkdir ~/newservPersist/players
+mkdir ~/newservPersist/teams
+mkdir ~/newservPersist/licenses
+```
+
+Copy config file to config dir
+```
+cp ~/newserv/system/config.example.json ~/newservPersist/config.json
+```
+
+Edit config.json
+```
+nano ~/newservPersist/config.json
+```
+Pro tip:
+Set "LocalAddress" to the static, LAN IP address of your server. If your server LAN IP is "192.168.0.10":
+"LocalAddress": "192.168.0.10",
+
+Set "ExternalAddress" to the WAN IP address of your network. If your WAN IP is "8.8.8.8":
+"ExternalAddress": "8.8.8.8",
+
+For Dolphin > Settings. Set SP1 to "Broadband Adapter (HLE)" Click [...] next to this, and set the DNS to the IP address of your server. Then start the game. Changes will not take affect if the game is running.
+
+Docker run. Remember to change /home/changeme/newservPersist to your persistent directory. Do not use aliases such as '~'
+```

+List of differences in Ep3 NTE compared to Final:
+- Assist cards
+- - Dice Fever sets dice to 6, not 5, and there is no Dice Fever +
+- - Rich + and Charity + also don't exist
+- - Powerless Rain, Brave Wind, Influence, Fix apply at a different phase of the attack procedure
+- - Tech Field applies to SCs only; on Final, it applies to SCs and creatures
+- - The denominator for Vengeance is 2; on Final it's 3
+- - AP Absorption logic is different (TODO: see apply_ap_and_tp_adjust_assists_to_attack)
+- - God Whim can use ANY assist card, not only the normally-obtainable ones, and it assigns all 4 players an assist, not only those who already had assists
+- - Inflation and Deflation only cause +1 or -1 cost per action, not per card
+- - Exchange can be set on other players
+- - The SET_MV condition overrides Snail Pace and Stamina completely
+- - Stamina sets your effective MV to 99 instead of 9
+- - Land Price is 2x instead of 1.5x
+- - Shuffle All and Shuffle Group don't respect deck shuffle/loop disabled settings
+- - Assist Vanish clears immediately, which means it can override other assists that happen at the same time (Trash 1, Empty Hand, etc.); in Final it happens after those
+- Abilities
+- - Rampage and Pierce are not player-specific; that is, if an attack has Rampage against one target, it has Rampage against all targets (this distinction is important for conditional abilities like Major Rampage and Heavy Pierce)
+- - Several abilities don't exist (TODO: Which ones? 0x64 and above?)
+- - Abnormal conditions do not have priorities like they do on Final
+- - Ability Trap seems incompletely implemented (or not implemented at all?)
+- - It appears that Major Pierce doesn't work against Arkz SCs, and this was fixed in Final
+- Conditions
+- - Anti-Abnormality doesn't prevent Freeze, Drop, Guom, or Curse
+- - SCs can get Freeze (they can't in Final)
+- - Bosses do not have automatic Anti-Abnormality
+- - Ability Trap prevents all abnormal conditions
+- Traps
+- - Traps trigger as soon as you move into their tile; on Final, they trigger at the end of the Move phase
+- - Traps may use any assist card, and this can be configured in the map definition (TODO: verify this last part)
+- Rules
+- - Dice Boost does not exist
+- - ATK and DEF dice ranges can be set independently, but there are only 7 options for each: 1-6, 1-1, 2-2, 3-3, 4-4, 5-5, 6-6
+- - There may be a bug when either die is set to 1-1 so you'll always get 2 instead (TODO: verify this)
+- COM interference is not implemented
+- The target's defense power is computed after checking if the attack is Resta instead of before
+- Card definitions
+- - The n21 and n22 arg2 conditions don't exist
+- - The p25 condition finds cards with Paralyze or Fly in NTE, vs. Aerial or Fly in Final; looks like a copy-paste error by Sega
+- - The p36 condition includes SCs and items on NTE, but only SCs on Final
+- - The p41 condition includes only your team on NTE, but both teams on Final
+- - Several tokens can't be used in expr fields: ddm, sat, edm, ldm, rdm, fdm, ndm, ehp
+- Missing rule checks
+- - Boss SCs can use items
+- - Move logic is different, which I didn't reverse-engineer because I was too lazy and couldn't imagine how it could be meaningfully different from Final
+- - Many values are not clamped (in Final, many are clamped to 0-9 or -99-99)
+- - You can set cards that aren't actually in your hand
+- - The game assumes team A always is at the top facing down and team B is always at the bottom facing up; if the map defines them to start on different edges or facing different directions than expected, the creature summoning areas will be wrong
+- - Character HP rule completely overrides the HP stat on SC cards; in Final, the SC's HP stat is added to Character HP
+- - Boss SCs are not exempt from this either; they have the same HP as normal SCs
+- - Cards marked as dead but not yet deleted can still attack
+- - The HOLD (6) and CANNOT_DEFEND (7) conditions don't actually stop you from defending
+- - There is no hard limit of 1000 turns for any battle
+- - In case of a draw, the first two tiebreaker rules (number of dead SCs and remaining SC HP) are skipped
+- The server cannot override EXP result values (thus post-battle EXP loss cannot be disabled)
+- Surprisingly, the code for PBs is identical between NTE and Final; it seems like they didn't spend any time on PBs after NTE at all

+########################################################################
+                Restore JP PSOBB original IME Behavior
+########################################################################
+
+The default Tethealla client included a custom patch to disable the IME
+system in-game which allows you to type in Japanese (presumably to allow
+English versions of Windows to type properly)
+
+However, if you plan to play PSOBB in it's original Japanese language it 
+is recommended you remove this patch to restore the original functions
+
+
+Open a unpacked PSOBB.exe in a hex editor and:
+
+FIND 9CC38E
+
+REPLACE WITH A8838F
+
+
+Make sure to install Japanese Language Support in Windows 10/11 to enable
+the Japanese keyboard and IME.
+
+If there's a problem, you can also use the Legacy IME by heading into the 
+options of the Japanese Language settings and scroll down to the bottom of 
+the page to enable Legacy IME Support to restore the original Pre-Windows 7
+IME system. 
+
+Last but not least, remember the default Tethealla client is the original 
+Japanese client, so you don't need to apply any other special patch but this
+one and make sure you have the original Japanese files set in your data folder
+the game should start entirely in Japanese.
