newserv - a Phantasy Star Online Swiss Army knife\n\
\n\
Usage:\n\
newserv [options]\n\
\n\
With no options, newserv runs in server mode. PSO clients can connect normally,\n\
join lobbies, play games, and use the proxy server. See README.md and\n\
system/config.json for more information.\n\
\n\
When options are given, newserv will do things other than running the server.\n\
Specifically:\n\
--compress-data\n\
--decompress-data\n\
Compress or decompress data using the PRS algorithm.\n\
--decrypt-data\n\
--encrypt-data\n\
Read from stdin, encrypt or decrypt the data, and write the result to\n\
stdout. By default, PSO V3 encryption is used, but this can be overridden\n\
with --pc or --bb. The --seed option specifies the encryption seed (4 hex\n\
bytes for PC or GC, or 48 hex bytes for BB). For BB, the --key option is\n\
required as well, and refers to a .nsk file in system/blueburst/keys\n\
(without the directory or .nsk extension). For non-BB ciphers, the\n\
--big-endian option applies the cipher masks as big-endian instead of\n\
little-endian, which is necessary for some GameCube file formats.\n\
--find-decryption-seed\n\
Perform a brute-force search for a decryption seed of the given data.\n\
The ciphertext is specified with the --encrypted= option and the expected\n\
plaintext is specified with the --decrypted= option. The plaintext may\n\
include unmatched bytes (specified with the ? operator), but overall it\n\
must be the same length as the ciphertext. By default, this option uses\n\
PSO V3 encryption, but this can be overridden with --pc. (BB encryption\n\
seeds are too long to be searched for with this function.) By default,\n\
the number of worker threads is equal the the number of CPU cores in the\n\
system, but this can be overridden with the --threads= option. To use a\n\
rainbow table instead of computing the cipherstreams inline, use the\n\
--rainbow-table=FILENAME option.\n\
--generate-rainbow-table=FILENAME\n\
Generate a decryption table for V3 encryption (or V2 if --pc is given).\n\
The --match-length= option must be given, which specifies the match\n\
length for the table. The total table size is the match length * 4 GB.\n\
As for --encrypt-data, the --big-endian option specifies that the table\n\
uses big-endian encryption. As for --find-decryption-seed, the --threads\n\
option specifies the parallelism for generating the table.\n\
--decode-sjis\n\
Apply newserv\'s text decoding algorithm to the data on stdin, producing\n\
little-endian UTF-16 data on stdout.\n\
--decode-gci=FILENAME\n\
--decode-dlq=FILENAME\n\
--decode-qst=FILENAME\n\
Decode the given quest file into a compressed, unencrypted .bin or .dat\n\
file (or in the case of --decode-qst, both a .bin and a .dat file). The\n\
--decode-gci option can be used to decrypt encrypted GCI files. If you\n\
know the player\'s serial number who generated the GCI file, use the\n\
--seed= option and give the serial number (as a hex-encoded integer). If\n\
you don\'t know the serial number, newserv will find it via a brute-force\n\
search, but this will likely take a long time.\n\
--cat-client=ADDR:PORT\n\
Connect to the given server and simulate a PSO client. newserv will then\n\
print all the received commands to stdout, and forward any commands typed\n\
into stdin to the remote server. It is assumed that the input and output\n\
are terminals, so all commands are hex-encoded. The --patch, --dc, --pc,\n\
--gc, and --bb options can be used to select the command format and\n\
encryption. If --bb is used, the --key option is also required (as in\n\
--decrypt-data above).\n\
--replay-log=FILENAME\n\
Replay a terminal log as if it were a client session. This is used for\n\
regression testing, to make sure client sessions are repeatable and code\n\
changes don\'t affect existing (working) functionality.\n\
--extract-gsl=FILENAME\n\
Extract all files from a GSL archive into the current directory.\n\
\n\
A few options apply to multiple modes described above:\n\
--parse-data\n\
For modes that take input on stdin, parse the input as a hex string\n\
before encrypting/decoding/etc.\n\
--config=FILENAME\n\
Use this file instead of system/config.json.\n\
