 2. *BB games are mostly playable, but there are still some unimplemented features (for example, some quests that use rare commands may not work). Please submit a GitHub issue if you find something that doesn't work.*
 3. *Support for PSO Dreamcast Trial Edition and the December 2000 prototype is somewhat incomplete and probably never will be complete. These versions are rather unstable and seem to crash often, but it's not obvious whether it's because they're prototypes or because newserv sends data they can't handle.*
 4. *Creating a game works and battle setup behaves mostly normally, but starting a battle doesn't work.*

 For example, the GameCube version of Lost HEAT SWORD is in two files named `q058-ret-gc-e.bin` and `q058-ret-gc.dat`. newserv knows these files are quests because they're in the system/quests/ directory, it knows they're for PSO GC because the filenames contain `-gc`, it knows this is the English version of the quest because the .bin filename ends with `-e` (even though the .dat filename does not), and it puts them in the Retrieval category because the filenames contain `-ret`.
 
+The GameCube and Xbox quest formats are very similar, but newserv treats them as different. If you want to use the same quest file for GameCube and Xbox clients, you can make one a symbolic link to the other.

 The type identifiers (`b`, `c`, `d`, `e`, or `q`) and categories are configurable. See QuestCategories in config.example.json for more information on how to make new categories or edit the existing categories.
 
 There are multiple PSO quest formats out there; newserv supports all of them. It can also decode any known format to standard .bin/.dat format. Specifically:
