notes: |
  Quake engine by LadyHavoc, maintained by the Xonotic project. RetroPie
  builds the div0-stable branch with two patches touching gl_textures.c
  and makefile.inc only (scriptmodules/ports/darkplaces-quake.sh). It runs
  `darkplaces-sdl -basedir $romdir/ports/quake -game <dir>`, where <dir> is
  the folder of the pak0.pak picked in the ports menu (runcommand.sh
  %QUAKEDIR%). The menu lists id1, hipnotic, rogue and dopa when their
  pak0.pak exists, and the install drops the shareware id1/pak0.pak of
  quake106.zip (scriptmodules/libretrocores/lr-tyrquake.sh,
  game_data_lr-tyrquake, _add_games_lr-tyrquake).

  The default game mode reads id1 under the base directory
  (common.c:1450). -game hipnotic and -game rogue switch to the mission
  pack modes, which add their own folder after id1 (common.c:1451-1452,
  1515-1540, fs.c:1433-1446). Any other -game folder is added on top as a
  mod (fs.c:1448-1462, 2154-2168). FS_AddGameDirectory mounts every .pak
  in a folder in sorted order, then every .pk3, so names past pak9.pak are
  accepted (fs.c:1266-1308). gfx/pop.lmp, present only in the registered
  id1/pak1.pak, sets the registered cvar (fs.c:1484-1505). No pak is
  hashed or checked against a file count.

  gfx.wad is read from the mounted paks (wad.c:125-131), and a missing
  gfx/palette.lmp falls back to the internal palette (palette.c:301-306).
  quake.rc, default.cfg and progs.dat also come from the paks, so a base
  folder without them leaves the engine at its console.
