Technical notes

Doom 3 source port based on the id Software GPL release of the Doom 3 engine (idTech 4). Carries the original Doom 3 1.3.1 game code plus bug fixes, SDL abstraction and 64-bit cleanup.

Game data is read from the pak files of base/, or from demo/ when base/ yields no default.cfg. Resurrection of Evil goes in d3xp/. ref: neo/framework/FileSystem.cpp:88-112 ("either base or demo"), neo/framework/FileSystem.cpp:2089 AddGameDirectory, neo/framework/FileSystem.cpp:2235 SetupGameDirectories(BASE_GAMEDIR) BASE_GAMEDIR is defined as "base" (neo/framework/Common.cpp:2724).

Pak loading scans the gamedir for *.pk4 and loads them in descending order so a later pak overrides earlier ones. ref: neo/framework/FileSystem.cpp:2125-2143 (ListOSFiles ".pk4").

When default.cfg cannot be read and fs_game is unset or "base", the engine sets fs_game and fs_game_base to "demo" and restarts the file system on the demo data. With any other fs_game it stops with "Couldn't load default.cfg". ref: neo/framework/FileSystem.cpp:2703-2716
