Doom 3 source port based on dhewm3 (GPL Doom 3 engine). The core accepts
|
||||
.pk4 extensions (retro_get_system_info sets valid_extensions = "pk4").

Content is loaded directly from the .pk4 file path - the engine extracts

the grandparent directory as fs_basepath (libretro.cpp:1097,1135-1136

the grandparent directory as fs_basepath (libretro.cpp:2381,2449-2450

Doom 3 directory layout with base/ containing pak000.pk4 through pak008.pk4.
|

BASE_GAMEDIR is hardcoded to "base" (Licensee.h:58). The boom3_xp variant
|

compiles with _D3XP defined, which passes "+set fs_game d3xp" at startup

BASE_GAMEDIR is hardcoded to "base" (Licensee.h:58). One binary serves both

games: content in a directory named d3xp, or the doom_game core option,

The filesystem code (FileSystem.cpp:2207)

scans for .pk4 files in the game directory and loads them in order, with

higher-numbered paks overriding lower ones. The core requires OpenGL
