 - Fix some edge cases on the BB proxy server (e.g. make sure Change Ship does the right thing, which is not the same as what it should do on other versions).

 There is no public editor for Episode 3 maps and quests, but the format is described fairly thoroughly in src/Episode3/DataIndex.hh (see the MapDefinition structure).

 You can also put DOL files in the system/dol directory, and they will appear in the Programs menu. Selecting a DOL file there will load the file into the GameCube's memory and run it, just like the old homebrew loaders (PSUL and PSOload) did. For this to work, ReadMemoryWord.s, WriteMemory.s, and RunDOL.s must be present in the system/ppc directory. This has been tested on Dolphin but not on a real GameCube, so results may vary.

 I mainly built the DOL loading functionality for documentation purposes. By now, there are many better ways to load homebrew code on an unmodified GameCube, but to my knowledge there isn't another open-source implementation of this method in existence.
