+  Android package com.karin.idTech4Amm, arm64-v8a and armeabi-v7a, Android 4.4+,
+  GPLv3, forked from n0n3m4's DIII4A. A Java launcher picks a game and a command
+  line, then loads one of twenty-six engine libraries into the Q3E frontend,
+  which owns the GL surface, the on-screen controls and the audio path. Another
+  application starts a game directly through com.n0n3m4.q3e.Q3EMain with a `game`
+  extra carrying the game token and a `command` extra carrying an argument vector
+  that begins with `game.arm`.

+
+  Game data lives under a working directory, `/sdcard/diii4a` unless the
+  preference names another, and each game reads a base folder inside it. With the
+  standalone-directory preference on, which is the default, the base folder sits
+  under a per-game subdirectory; with it off, games that are not marked always
+  standalone read the base folder directly under the working directory. The Dark
+  Mod, UZDOOM, FTEQW, ECWolf, Xash3D, Source and both Serious Sam entries are
+  always standalone and keep their subdirectory either way.

+  Engine, standalone directory and base folder per game, in registration order:

+  prey/preybase), Enemy Territory: QUAKE Wars (Splash Damage idTech4,
+  etqw/etqwbase), DOOM 3 BFG (RBDOOM-3-BFG 1.4.0, doom3bfg/base), The Dark Mod
+  2.14 (darkmod), Skin Deep 1.0.4 (skindeep/base), Quadrilateral Cowboy
+  1.0.2602252 (qc/base), Icarus Starship Command Simulator 1.0.9 (icarus/base),
+  Quake III Arena (ioquake3 1.36, quake3/baseq3), Return to Castle Wolfenstein
+  (iortcw 1.51d, rtcw/main), Wolfenstein: Enemy Territory (ET: Legacy 2.83.2,
+  etw/etmain), Jedi Academy (OpenJK 1.0.1.1, openja/base), Jedi Outcast (OpenJK
+  1.0.1.1, openjo/base), Medal of Honor: Allied Assault (OpenMOHAA 0.82.1,
+  openmohaa/main), Urban Terror (Q3-UT4 4.3.4, urt/q3ut4), RealRTCW 5.43
+  (realrtcw/Main), Quake II (Yamagi 8.60, quake2/baseq2), Quake (Darkplaces,
+  quake1/darkplaces/id1), UZDOOM 4.14.3 (uzdoom), Wolfenstein 3D (ECWolf 1.4.2,
+  ecwolf), FTEQW 1.05 (fteqw), Xash3D 0.21 (xash/valve), Source Engine 1.16
+  (srceng/hl2), Serious Sam TFE 1.10.7 (serioussamtfe) and Serious Sam TSE 1.10.7
+  (serioussamtse). Every one is built in this configuration; the F-Droid flavour
+  leaves out Xash3D and Source, and the idtech flavour leaves out those two and
+  Serious Sam. DOOM 3 BFG carries a second library for its Vulkan renderer.

+
+  The retail data is what the user brings, and no engine here names its archives
+  one by one. The idTech 4 lineage lists `.pk4` in the game directory, DOOM 3 BFG
+  lists `.resources`, Yamagi walks `pak0` through `pak99` for each of its four
+  container suffixes and then globs the rest, and Serious Sam globs `*.gro`. What
+  every id-derived engine does gate on is `default.cfg` inside those archives: an
+  empty read is a fatal error, and only the Splash Damage build is compiled past
+  the check. UZDOOM ends with "Cannot find a game IWAD" when no known IWAD is
+  present, and ECWolf with "Can not find base game data. (*.wl6, *.wl1, *.sdm,
+  *.sod, *.n3d)". The launcher carries a store or homepage link per game and mod
+  so the data can be bought or downloaded.

+
+  The Quake III lineage keeps id's release checksums for `baseq3` pak0 through
+  pak8 and `missionpack` pak0 through pak3, and an archive whose value disagrees
+  only draws a console warning telling the user to re-copy from the CD or
+  re-install the point release. Those numbers are a block checksum over the CRCs
+  of the archive members, not a hash of the file, so they identify a release
+  rather than validate a download.

+
+  UZDOOM reads the IWAD names it will accept from `iwadinfo.txt` inside
+  `game_support.pk3`: the DOOM, DOOM II, Final DOOM, BFG and KEX re-releases,
+  Freedoom, Heretic, Hexen, Strife, Blasphemer, Chex Quest, Action Doom 2, HacX,
+  Harmony, Square, Delaweare and Return of the Triad, forty-nine names. The
+  launcher itself names four of them as selectable data files, DOOM.WAD,
+  DOOM2.WAD, freedoom1.wad and freedoom2.wad, because UZDOOM and ECWolf are the
+  two games whose data is a file rather than a folder.

+
+  Starting a game extracts that game's bundled resources first. A text file named
+  `idtech4amm.version` is written beside them and compared on the next run, so an
+  engine update replaces the copy and a user edit survives otherwise. The Dark
+  Mod, DOOM 3 BFG, UZDOOM, Xash3D, Source, Enemy Territory, ECWolf, Skin Deep and
+  ETQW are covered by this path; the bot, Rivensin and translation archives are
+  extracted on request from the launcher instead.

+  On-screen button images are read through a search path built from the working
+  directory, the external files directory of the package, its internal data
+  directory and the assets of the apk, plus every `.zipak` archive found in the
+  first three. A file of the same name in any of them replaces the built-in
+  image, and a folder under `controls_theme/` becomes a named theme in the
+  chooser, described by a `description.txt` that may be suffixed with a language
+  tag.

+notes: |
+  NES and Famicom emulator by Marat Fayzullin, covering cartridges, the Famicom
+  Disk System and the VS System. The build read here is the free Android APK the
+  author publishes himself, package com.fms.ines versionName 6.1.4 versionCode
+  6104, apk md5 d0e1b93b09d4b58294efd4e1509e25ca, signed CN=Marat Fayzullin
+  O=Garage Research issued 2011, sha256
+  d09469e9b550cbc9005d3bd089f3df5f0ba89cba71cdd3b33736a0382d6f9848; the two
+  download paths on that site serve the same bytes. Google Play carries the
+  emulator as com.fms.ines.free, the package ES-DE launches, and inside VGBAnext
+  as com.fms.ng, the author recording that Play removed the original com.fms.ines
+  listing over its built-in cheats. The native libraries keep their symbol
+  tables, so the readings below cite libmain.so offsets in the x86_64 slice; the
+  arm64-v8a, armeabi-v7a, armeabi and x86 slices carry the same filename set. The
+  free iNES 6.1 builds for Windows and Ubuntu were read beside it and open the
+  same files under the same names. No source has ever been published: the author
+  releases ColEm and fMSX as source archives, while every iNES download on the
+  same site, from 0.7 for AIX and SunOS through 6.1, is a binary package.

+
+  One directory holds everything the emulator reads. MainActivity hands
+  EMULib.k() to jniStart, which copies it into the buffer GetHomeDir returns and
+  passes that same buffer to SetPrivateDir. Every open goes through mopen, which
+  calls OpenRealFile: the name is tried as given and again as
+  <PrivateDir>/<basename>, and when both open the larger of the two is kept. That
+  directory is <ExternalStorage> joined with the application label up to its first
+  space, so iNES, falling back to getExternalFilesDirs(null) when the path is not
+  a writable directory. mopen layers gzdopen over the result, so any of these
+  files also opens gzipped, and a content:// name is routed to the Android storage
+  framework instead.

+
+  DISKSYS.ROM is the only filename compiled into the emulator. LoadFDS reads the
+  disk image first, taking a bare *NINTENDO-HVC* header or the 16 byte FDS wrapper
+  ahead of it, then opens DISKSYS.ROM and reads 0x2000 bytes into RAM at 0xE000. A
+  failed open leaves the status at NOT FOUND and a short read at FAILED, and
+  either makes LoadFDS return zero, so the disk never starts. Nothing about the

+  The startup palette is <HomeDir>/iNES.pal, assembled in Application from
+  GetHomeDir and held in PalName, which StartNES loads when it is set. LoadPAL
+  reads the first 256 bytes: exactly 192 is taken as 64 RGB triples fed to
+  SetColor one at a time, anything else is parsed as text. A missing file leaves
+  the built-in palette in place. The desktop distribution ships twenty candidates
+  under Palettes/ to copy into that single name, the Android package none.

+  assets/names.dat fills the title lookup and is then extended by

+  cheat browser, its Include lines pulling further sets through the same lookup,
+  which falls back to <HomeDir>/Cheats and to the home directory itself.

+  Android package me.dt2dev.infinity, closed source, free with ads on Google Play.
+  Two builds are read here, versionCode 501 (versionName 5, minSdk 32, targetSdk 37,
+  xapk sha256 d0040583814a634c9aa2ff56b8245f1eb94f33ee0785c264bccfa5188cd3a273) and
+  versionCode 404 (minSdk 30), both carrying lib/arm64-v8a, the Play app signing
+  certificate sha256
+  eb7b3dd469cf44ab614abda7a367c20de540014a37bb2b915dffecf5f3268da2 and the Play
+  distribution source stamp.
+
+  The engine is fake-08 compiled into libinfinity.so and driven through a nine
+  method JNI bridge. Its Lua blobs are upstream: the settings cart is byte identical
+  to fake-08 814991a and the default cart differs only where VER_STR is spliced, the
+  Android build leaving that macro undefined so the boot cart reports v0.0.0.0. The
+  global Lua glue is patched in five places, all in the pause menu, where "exit to
+  menu" and "exit to settings" give way to a single "quit game" calling the native
+  __quitgame, navigation wraps around and the menu holds eight items instead of
+  nine. No menu entry reaches the cart browser or the settings cart any more, the
+  Compose interface listing the library instead.

+       libinfinity.so arm64 .rodata DefaultCart / FakoSettings / p8GlobalLuaFunctions
+       blobs, symbol __quitgame
+
+  A cart never reaches the engine as a path. Java reads the bytes into a direct
+  ByteBuffer, from the application assets for a built-in cart or through the content
+  resolver for anything else, then hands the buffer to nativeStart with the save
+  state name <cart>.ss and the application's internal files directory, where a cdata
+  subdirectory holds the <id>.p8d.txt cart data files. No storage permission is
+  declared: the cart library is a directory tree granted through the storage access
+  framework, and the only write outside internal storage is the .nomedia file that
+  the "Show Carts in Photos" switch creates or deletes there.

+
+  ES-DE targets me.dt2dev.infinity/.SchemeActivity with a VIEW intent on its own
+  content provider. The activity reads the display name from the provider, accepts
+  it only when it ends in .p8 or .p8.png, strips that extension and forwards
+  infinity://game with cart_uri, filename, save_state=false and assets=false to
+  MainActivity. The manifest filter announces the content scheme with the image/png
+  type, which an explicit component bypasses.
+  ref: SchemeActivity.java:25-84, AndroidManifest.xml activity me.dt2dev.infinity.SchemeActivity
+
+  Two graphics backends. OpenGL ES is the default and carries its three fragment
+  programs as GLSL string literals inside the library. Vulkan, offered as beta,
+  reads SPIR-V modules from the application assets instead, one vertex module plus
+  one fragment module chosen by the display filter. Version 501 ships no shader
+  asset at all, version 404 ships the four listed below, and both libraries name
+  them; the loader takes no null check between AAssetManager_open and
+  AAsset_getLength. The manifest requires only abi and density splits, so no asset
+  pack can deliver them separately.
