  Wolfenstein: Enemy Territory source port. BASEGAME = "etmain"
  (src/qcommon/qcommon.h:787). FS_InitFilesystem (src/qcommon/files.c:
  5066-5094) refuses to start if pak0.pk3 is not reachable under etmain
  and prints "Please copy pak0.pk3 from the 'etmain' path of your
  Wolfenstein: Enemy Territory installation to <path>". pak1.pk3 and
  pak2.pk3 are checked against the server's requested pak list in
  FS_ComparePaks (src/qcommon/files.c:4011-4018) but neither is a
  startup gate; third-party mods pull them in as needed (see README.md
  "In addition, third party mods might also require pak1.pk3 and
  pak2.pk3"). mp_bin.pk3 ships in the retail release and holds the
  stock multiplayer binaries.

  NUM_ID_PAKS = 9 (src/qcommon/qcommon.h:815) counts the names recognised
  by FS_idPak; retail Enemy Territory 2.60b publishes only pak0, pak1,
  pak2 and mp_bin, so the extra slots are reserved for forward compatible
  server lists, never filled by id.

  The ET Legacy project ships its own replacement etmain/ assets (configs,
  presets, locale files) directly in the source tree, plus a Legacy mod
  pk3 downloaded on first run. The user still has to supply the retail
  pak0.pk3 from the free Enemy Territory 2.60b download; pak0.pk3 holds
  every id map, model, texture and sound.
