Technical notes

Quake II source port. BASEDIRNAME = "baseq2" (src/common/header/common.h :36). FS_AddDirToSearchPath (src/common/filesystem.c:1646) loops pak%d.<ext> from 0 to MAX_PAKS-1 (=99) across fs_packtypes = { pak, pk3 } for the active game directory, loading each one as a protected pak. baseq2/pak0.pak is the retail data; id's 3.20 point release adds baseq2/pak1.pak, baseq2/pak2.pak and the Three Wave CTF data under ctf/.

Supported official mods are listed in first_mods[] (src/common/filesystem.c:1331) = { "baseq2", "xatrix", "rogue", "ctf" }. Mod game dirs are selected via the game cvar (FS_InitFilesystem + FS_BuildGameSpecificSearchPath, src/common/filesystem.c:2075-2097). Each mod ships its own pak0.pak / pak1.pak (The Reckoning, Ground Zero, Three Wave CTF). Zaero support uses the same path layout (game zaero) but no official repository under the yquake2 org.

The engine never hashes a pak. Validation is "does the pack read as a valid PAK header" (FS_LoadPAK, src/common/filesystem.c:873). Missing files produce "Couldn't load %s" at Com_Error level only for the baseq2 lookup when the game cannot find any game assets at all.

Background music is streamed from <game>/music/track02.ogg ... track22.ogg by OGG_InitTrackList (src/client/sound/ogg.c), not required for gameplay.
