+  Build-engine port by TerminX, Hendricks266, Plagman and others. Covers
+  Duke Nukem 3D (and its official addons), NAM, NAPALM, WWII GI and
+  Platoon Leader. Startup scans the search path for registered GRPs by
+  CRC32 (source/duke3d/src/grpscan.cpp:39-76 internalgrpfiles[]). Each GRP
+  carries a game flag (DUKE / NAM / NAPALM / WW2GI) and optional addon
+  dependency; EDuke32 picks the user selection, mounts it with
+  initgroupfile and loads the DEF / CON / RTS the GRP points to.
+
+  G_DefaultGrpFile (source/duke3d/src/common.cpp:60-73) returns the base
+  GRP for the active game flag: DUKE3D.GRP, NAM.GRP, NAPALM.GRP, WW2GI.GRP.
+  G_DefaultConFile and G_DefaultRtsFile pick EDUKE.CON / NAM.CON /
+  NAPALM.CON / WW2GI.CON and DUKE.RTS / NAM.RTS / NAPALM.RTS / WW2GI.RTS.
+
+  CRCs listed in source/duke3d/src/grpscan.h match the retail GRP byte
+  for byte; the loader only checks CRC32 (not MD5) and only to pick the
+  entry, never to refuse an unknown GRP. CON / RTS / addon files are
+  referenced from the chosen entry but their contents are not validated.

+  server lists, never filled by id.
+
+  The ET Legacy project ships its own replacement etmain/ assets (configs,

+  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

+  Ion Fury runs on EDuke32 built with FURY=1 (GNUmakefile:6-15), which
+  defines EDUKE32_STANDALONE and sets APPBASENAME=fury, APPNAME="Ion Fury".
+  In standalone mode the GRP-detection table of EDuke32
+  (source/duke3d/src/grpscan.cpp:38-77) is compiled out by #ifndef
+  EDUKE32_STANDALONE, G_DefaultGrpFile returns "(none)"
+  (source/duke3d/src/common.cpp:60-77), and the loader autoscans the search
+  paths for *.grp / *.zip / *.ssi / *.pk3 / *.pk4
+  (source/duke3d/src/common.cpp:913).
+
+  Search paths added for the Fury binary include the Steam install (Ion
+  Fury) and the GOG install (ION Fury), marked with SEARCHPATH_FURY
+  (source/duke3d/src/common.cpp:585-587, 622-625, 822-833). After scanning,
+  G_CleanupSearchPaths removes all non-FURY entries when the FURY game
+  flag is active (source/duke3d/src/common.cpp:850-851), so Fury only
+  reads from its own install directory.
+
+  No hash or filename is validated by the engine: Ion Fury ships one GRP
+  (fury.grp) that holds every map, art bank, sound and DEF the game needs,
+  plus a small number of top-level files the retail installers lay down
+  alongside it. Only the GRP is listed below; the other files

+  Quake III Arena / Team Arena source port maintained by the ioquake
+  team. BASEGAME = "baseq3", BASETA = "missionpack" (code/qcommon/q_shared.h
+  :44,65). FS_Startup (code/qcommon/files.c:3360) scans each search path
+  for pak0.pk3 through pak(NUM_ID_PAKS-1).pk3 under baseq3, and up to
+  NUM_TA_PAKS paks under missionpack (code/qcommon/qcommon.h:591-593,
+  NUM_ID_PAKS=9, NUM_TA_PAKS=4).
+
+  Loaded paks are matched against hardcoded unsigned 32-bit checksums
+  (code/qcommon/files.c:178-198: pak_checksums[], missionpak_checksums[]).
+  These are NOT MD5 / SHA1 / CRC32 of the file; they are id's own custom
+  pak checksum (sum of each lump CRC, see FS_LoadZipFile). A mismatch
+  prints "WARNING: baseq3/pak0.pk3 is present but its checksum (%u) is
+  not correct" (code/qcommon/files.c:3574) and keeps running: the loader
+  does not refuse the file, so no md5/sha1 is written below.
+
+  Missing paks are only fatal when neither com_standalone nor fs_basegame
+  override the base game (code/qcommon/files.c:3697, 3738).

+notes: |
+  SDL2 port of Rise of the Triad by Fabian Greffrath, forked from the
+  original 1995 Apogee/3D Realms source release.
+
+  Build-time switch: SHAREWARE=0 (default, "registered") expects
+  DARKWAR.WAD / DARKWAR.RTL / DARKWAR.RTC; SHAREWARE=1 (dropped by the
+  CMakeLists SHAREWARE option) expects HUNTBGIN.WAD / HUNTBGIN.RTL /
+  HUNTBGIN.RTC (rott/rt_main.h:33-45). The repo distributes the
+  non-shareware binary; shareware builds are compiled by users from the
+  same tree.
+
+  Startup assembles argv in SetupWadFile (rott/rt_main.c:808-842), joining
+  `datadir` and STANDARDGAMEWAD, then feeds it to W_InitMultipleFiles
+  (rott/rt_main.c:842, rott/w_wad.c). The WAD search tries each path
+  registered through add_datadir() (rott/rt_datadir.c:198-209); a missing
+  main WAD aborts with FileNotFoundError(STANDARDGAMEWAD)
+  (rott/rt_main.c:812).
+
+  Game-product detection runs after the main WAD opens: FindFileByName
+  (rott/rt_main.c:165-177) looks for ROTTSITE.RTC (site license),
+  ROTTCD.RTC (SuperROTT, i.e. ROTT CD extra battle levels), and
+  DARKWAR.RTC (registered battle levels), setting gamestate.Product to
+  ROTT_SITELICENSE, ROTT_SUPERCD or ROTT_REGISTERED. Shareware builds
+  stay on ROTT_SHAREWARE.
+
+  REMOTE1.RTS carries the "Remote Ridicule" speech bank; its absence is
+  silently tolerated (rott/rt_main.c:830-834).
+
+  No hash is validated — the loader relies on WAD lump names and the
+  SHAREWARE_TAG magic number inside the RTL (rott/rt_ted.c:1432).

+notes: |
+  GoldSrc / Half-Life 1 engine reimplementation by Flying With Gauss.
+  Game directories are discovered at startup: FS_CheckForXashGameDir
+  (filesystem/gameinfo.c:611-634) walks each sub-folder of the base path
+  and keeps the ones that contain gameinfo.txt or liblist.gam.
+  FS_ParseGenericGameInfo (filesystem/gameinfo.c:231-430) reads the mod
+  descriptor out of either file: `basedir` names the fallback game
+  (chained one level, e.g. czeror -> czero -> cstrike -> valve, see
+  filesystem/searchpath.c:327), `fallback_dir` names a second fallback,
+  and `game` / `gamename` carry the human-readable title.
+
+  Each supported mod's data is a Valve-style game folder with its own
+  pak0.pak / pak1.pak, maps/, models/, sound/, overviews/ and a game
+  descriptor. The engine does not hash any file; the pak header is the
+  only sanity check (filesystem/pak.c). liblist.gam ships inside each
+  retail mod and is also written out by the engine as gameinfo.txt the
+  first time it imports a Valve folder (filesystem/gameinfo.c:538-544).
+
+  A Quake-engine game dir is recognised separately by
+  FS_CheckForQuakeGameDir (filesystem/gameinfo.c:578-603), which looks
+  for pak0.pak + progs.dat / quake.rc; Xash3D FWGS can run Quake 1 total
+  conversions this way.
+
+  Below are the folders Half-Life retail / official addon releases
+  install under the Steam install root. Each entry marks the per-mod
+  descriptor and base pak so the engine can detect the game; map / model
+  / sound trees that live beside them are too open-ended to enumerate
+  and are counted as part of the same game data.

+  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.
+  retail Quake II ships only pak0.pak and pak1.pak; later paks are
+  consumed by community mods and the Nightdive remaster.
+
+  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.
