Abdessamad Derraz 8b203e397c chore: mark what the new profiles' installs bring 
The profiles written for RetroBat and RetroPie were checked the same way: UZDoom, LZDoom, SRB2 and AdvanceMAME data ship with their releases, RetroPie installs the shareware Doom, Quake III and Wolfenstein data, the Aleph One scenarios and 4DOS beside the ports it builds, RetroBat installs Jynx's ROMs, and Recalbox's uae4all core comes without the AROS ROMs.

notes: |
Legacy branch of GZDoom 3.x maintained by drfrag for older GPUs and
OpenGL 2 hardware, built as lzdoom. The profiled revision is tag 3.88b,
the one RetroPie builds. version.h names the engine resources: BASEWAD
lzdoom.pk3 and OPTIONALWAD game_support.pk3 (src/version.h:90-91).
Engine resources (built from the wadsrc directories by add_pk3):
lzdoom.pk3 searched first in the program directory, fatal
"Cannot find lzdoom.pk3" when absent
ref: src/d_main.cpp:2530-2534, wadsrc/CMakeLists.txt:3
game_support.pk3 loaded after lzdoom.pk3 when found
ref: src/d_main.cpp:2537, src/d_iwad.cpp:757-763
lights.pk3 autoloadlights, false by default
brightmaps.pk3 autoloadbrightmaps, false by default
ref: src/d_main.cpp:228-229, 2164-2178
A GAMEINFO lump can switch the last two on. Neither is read for a
shareware IWAD. game_widescreen_gfx.pk3 and game_conpics_gfx.pk3 are
looked up too, both on by default (src/d_main.cpp:230-231, 2179-2190),
but no wadsrc directory of this tree builds them.
BaseFileSearch tries the program directory first for these files, then
the name as given, then the FileSearch.Directories of the configuration
(src/d_main.cpp:1793-1830). On Linux those default to $HOME/.config/lzdoom,
SHARE_DIR, /usr/local/share/doom, /usr/local/share/games/doom,
/usr/share/doom, /usr/share/games/doom and $DOOMWADDIR
(src/gameconfigfile.cpp:153-172).
Game data is a user-supplied IWAD. iwadinfo.txt declares each known IWAD
with the lumps it must contain, its file name and the support files it
loads. Each IWADSearch directory (".", $DOOMWADDIR, $HOME/.config/lzdoom
and the four share directories on Linux, src/gameconfigfile.cpp:126-149)
is scanned for the names of the Names block and for any .iwad, .ipk3 or
.ipk7 file, and each candidate is identified by its lumps, not by its name
(src/d_iwad.cpp:319-367, 466-499, 509-527). The Names block also lists
doomu.wad, bfgdoom2.wad, doom2bfg.wad, bfgdoom.wad, doombfg.wad,
doomxbox.wad, doom2xbox.wad, tntunity.wad, plutoniaunity.wad,
freedoomu.wad, freedoom.wad, hereticsr.wad, hexendemo.wad, hexdemo.wad,
strife0.wad, strife.wad and blasphem.wad
(wadsrc_extra/static/iwadinfo.txt:568-618). -iwad adds the named file,
trying .wad, .pk3, .iwad, .ipk3 and .ipk7 when it has no extension, and
the first usable one wins (src/d_iwad.cpp:566-602, 638-650). An IWAD that
declares Required is dropped unless the IWAD it names was found, and Load
files are read from the IWAD's own directory (src/d_iwad.cpp:610-635,
772-788). Startup stops with "Cannot find a game IWAD" when nothing is
identified (src/d_iwad.cpp:693-696). No hash is read.
MIDI music goes through FluidSynth with fluid_patchset "lzdoom"
(src/sound/music/music_config.cpp:118). The soundfont manager reads every
file of SoundfontSearch.Directories, keeping SF2, WOPL, WOPN and zipped
GUS patch sets by their header, and falls back to
$PROGDIR/soundfonts/lzdoom.sf2 when it found none
(src/gameconfigfile.cpp:175-202, src/sound/music/i_soundfont.cpp:330-380,
428-431). The OPL and OPN banks are read only with adl_use_custom_bank or
opn_use_custom_bank, off by default (src/sound/music/music_config.cpp:92-99,
253-260).
RetroPie installs lzdoom.pk3, game_support.pk3, lights.pk3, brightmaps.pk3
and soundfonts/ beside the binary, leaves fm_banks/ out, and launches
"lzdoom -iwad <file>" with DOOMWADDIR set to its ports/doom directory, into
which it downloads doom1.wad and the Freedoom 0.13.0 IWADs.
