core_version is v0.1-12070: git describe at 4122fed9 counts 12,070 commits past tag 0.1, as gen_scmversion.sh does. The NTSC-U licence string is quoted as system.cpp:959 spells it, with its two spaces.
Read at each pinned commit: Azahar, Citra, Citra 2018, Panda3DS, Trident,
FS-UAE and Stella read these below the frontend save directory, Dolphin
and Ishiiruka below <save>/User, Cemu its MLC below <save>/Cemu. Each
profile names its library_name. Citra Canary reads sysdata from the
host data directory: its pin moves to the canary branch it is built from.
The buildbot's azahar_libretro is built from azahar-emu/azahar: the
2026-10-22 nightly carries g_scm_rev f570b53f (master, 2026-10-16) and
the key blob of src/core/hw/default_keys.h byte for byte. The profile
now reads that repository at tag 2126.2, whose file-loading code matches
f570b53f apart from licence headers.
The libretro core keeps its user directory under <save_dir>/Azahar/,
falling back to <system_dir>/Azahar/, so path: carries the Azahar/
prefix and standalone_path: the user directory layout. The embedded
keys.txt is the 2126.2 blob (sha1 5288772b). azahar-sa is ROCKNIX's
name for the same standalone.
KNULLI builds the SDL2 frontend of johndoe6345789/azahar_libretro at
c8d39853 as its azahar binary, so that fork moves to azahar-sdl.yml
with built_by: [knulli].
svg_bios.u49 is listed in svgpcbBIOSRomDesc (d_pgm.cpp:923-929), which only
STDROMPICKEXT(svgpcb, svgpcb, svgpcbBIOS) at line 7035 pulls in. The FBNeo
DAT likewise places it in svgpcb, and pgm's own list (pgmRomDesc, lines
879-892) has six members. The fbneo profile now files it under svgpcb.zip.
bios/Arcade/Arcade/pgm.zip is rebuilt as TorrentZip from the six members of
the FBNeo pgm recipe. The build is byte for byte the copy that was in
.variants/pgm.zip.6bbbce09, which goes. The two unpinned seven-member
copies (.variants/pgm.zip.931a4971 and MAME/.variants/pgm.zip.6ade4934)
go too: every member is still held, svg_bios.u49 as
bios/Arcade/FBNeo/svg_bios.u49. The pinned copies (87cc944e in MAME/,
68ef99a1 in .variants/) are untouched.
MAME renamed the Galaxy Games BIOS root from galgbios to galgames in 0.288 (galgames.cpp:1301, listxml of 0.288 and 0.289). mame.yml and mamearcade.yml document 0.289 yet still listed galgbios.zip; mamearcade lacked galgames.zip, which mame.yml already had. The release profiles mame0258 and mame0278 keep galgbios.
macs2os_l.bin and macs2os_h.bin are NO_DUMP from 0.135u4 to 0.289, and
handle_missing_file counts a missing NO_DUMP ROM as a warning or known
bad, never an error. recel is NO_DUMP at 0.258 as well. mame.yml,
mamearcade.yml, mame0258.yml and mame0278.yml come from the scraper
rerun, which also carries the systems mame.yml gained since 10-17.
Both pairs from the Real3D SDK disc (_SETUP.1): Bayou 0x64130009 at
Assets/, Orlando 0x64130005 in .variants/. The .pmem size check against
the .cmem header keeps a pair from mixing models.
chex.deh and french.deh come from idgames (themes/chex/chexdeh.zip, utils/exe_edit/patches/french.zip), both released with no restriction by their author.
The bare name mupen64plus is the standalone program on every platform that lists it (Batocera, KNULLI, Recalbox, RetroPie, ROCKNIX). The libretro buildbot publishes no core by that name, so mupen64plus_next no longer claims it.
dinothawr.game is the content file or, without content, system_dir/dinothawr/dinothawr.game. The copy is the one at the pinned revision, which references bg.apng; the 2013 buildbot archive carries an older manifest.
A type 5 level event loads newsh<char>.shp through shapeFile[34] with dir_fopen_die. The 31 banks the Tyrian 2.1 levels name are listed, those of episode 1 required, and taken from the freeware tyrian21.zip. newsh1 and newsh6 load on every run and are required.
The DOS data the engine reads from the content directory becomes structured game_data entries: level, global, monster, cutscene and subtitle files, the demo archive and CD probe, the Sega CD voice file and the Amiga music modules.
EmuELEC, AmberELEC and KNULLI launch standalone emulators by the name
their launch code dispatches on (HATARISA, PPSSPPSDL, FBNEOSA) and ship
32-bit or patched builds of libretro cores under their own .so names
(flycast_32b, mupen64plus_next_alt, genesis_plus_gx_cart_special,
mame0139, flycast-xtreme). Each name joins the profile of the project
its package builds. fceumm_mod reads gg.rom, not gamegenie.nes, and
never opens it, so it gets its own profile.
Both branches extracted RetroBat's Flycast BiosPath: value_folders
already produces the record, so the dedicated extractor is dropped and
its test reads the generic one.
DraStic opens nds_bios_arm9.bin, nds_bios_arm7.bin and nds_firmware.bin and checks their size. Its nine aliases are in none of its binaries, and neither platform launcher passes them: ROCKNIX links the two BIOS names from its bios folder, and RetroPie runs DraStic from $md_conf_root/nds/drastic (drastic.sh:48), now a passes_path record. The collection answers DraStic's names with its DS dumps in generate_db, where repository names belong.
standalone_path is relative to the directories a standalone build
resolves it against, now declared per profile (standalone_directories).
A launcher record that links or passes a whole folder of the BIOS tree
under one of them gives that folder, and platform_layouts rebases the
standalone view once for the builder, the manifest, verify and slots
(launchers.standalone_root, common.standalone_destination).
Flycast on RetroPie and ROCKNIX reads bios/dc, on EmuDeck
bios/flycast/bios, on Batocera (FLYCAST_BIOS_PATH) and RetroBat
(Dreamcast.BiosPath) bios/dc. The ROCKNIX, Batocera and RetroBat
scrapers now record the patched data directory, the environment
variable and the setting that say so.
RetroBat's launcher layer now records the Saturn names its generators
pick. The ymir aliases are the libretro port's own kBiosFilenames, and
the SSF aliases label dumps of a slot whose file name SSF leaves free.
Both entries now say so next to their source_ref.
The -listxml names the software lists each machine and slot card
declares and the floppy drives it can instantiate. --devices now writes
one entry per hash/<list>.xml the release ships under the systems of its
placed machines (111 lists, 666 stay with hash/), and files each floppy
sample under the systems whose drives select its form factor
(floppy.cpp:1428-1473, 1759-1767).
Machines a registered platform declares under one of the profile's
systems seed the walk too: bbcb, cdimono1, cdimono2, dragon32, ep64 and
ep128. Unplaced device sets go from 903 to 861.
6eabf224..6664c602 rewrites the .rom1 extension swap and shares one path buffer between the .nvm and .mec reads (BiosTools.cpp:189-230, CDVD.cpp:194-243). The names read and the fallbacks are unchanged. profile_sync: 0 to review.
The libretro port reads sega_101.bin, mpr-17933.bin and saturn_bios.bin in that order, gives the first two the JP and US_EU regions by hash, and loads the candidate the ymir_region option or the disc area code asks for (apps/ymir-libretro/src/libretro.cpp:305-309, 596-606, 627-702, 1231-1238, 1290-1306 at 8174cbbe). Area K maps to KR, which neither image carries.
The standalone build reads BIOS files from its data directory root, not from dc/ (core/oslib/oslib.cpp:118-196, core/stdclass.cpp:95-125, core/linux-dist/main.cpp:74-99). Each entry now carries standalone_path.

The semantic check read systems: only. mame2010 filed seven BIOS root
sets under systems its list lacked: cpzn1, cpzn2 (zn.c:4543, 4563),
konamigv (konamigv.c:877), skns (suprnova.c:1686), alg_bios (alg.c:782),
maxaflex (maxaflex.c:541) and hng64 (hng64.c:2189) are GAME_IS_BIOS_ROOT
in mame2010-libretro at source_commit.
The flycast standalone paths (eb04fb50) stay out until the packs read the
platforms' launcher links. Two rosalies-mupen-gui aliases that only
RetroBat's launcher writes leave the profile, now that its layer
records them.
