Dolphin and its forks map the Brazilian disc country code B, and the
SYSCONF countries of the Americas, to NTSC-U (DiscIO/Enums.cpp), whose
boot ROM is read from GC/USA. Tagged north-america alone, the IPL a
Brazilian disc boots left a --region brazil,europe pack. GC/USA/IPL.bin
in six profiles and triforce's IPL_TRI.bin now carry latin-america.
sms_cart_region_detect returns REGION_USA for any cartridge outside its
CRC list whose header is not Japanese, so Genesis Plus GX and its two
forks open bios_U.sms for Australian and Brazilian cartridges as well.
Tagged north-america and europe only, --region australia,japan dropped
it from the pack. The tag now adds latin-america and oceania.
The buildbot builds the stella core from stella-emu/stella master
(src/os/libretro), not from stella2014 code, and stella2023 claimed the
stella name. stella.yml now documents that tree at 2c3d7023: the KidVid
tapes are read from a stella folder under the save directory, loose or
in KidVidAudio.zip, and played. stella2023 keeps its own name only.
The tmss.md note lived under three pins, so profile_sync could not
tell which revision its three citations describe and refused any bump.
At 1e0de94d libblastem.c:514-529 is the tmss.md and bios_MD.bin lookup,
genesis.c:3036-3051 the fatal_error without a TMSS ROM and 3054-3065
the mirror loop, as the note says. prose_written_at names that pin.
libretro/ppsspp answers as libretro-mirrors/ppsspp-old, a 2020 tree
frozen in 2022. The buildbot builds ppsspp from hrydgard/ppsspp master,
whose libretro/ directory holds the wrapper, so the profile is read
again at 58935bbf and pinned there.
The asset directory, PPGe atlas and font lookup are cited where they
sit now. The notes record the NAND under the save directory that a
disc's firmware updater fills, and the modules it replaces.
libretro/flycast now answers as libretro/parallel-dc, a separate core.
The buildbot builds flycast from flyinghead/flycast master
(libretro-super recipes, cores-linux-x64-generic), so the profile is
read again at 34ad8c82 and pinned there.
At that revision the Dreamcast boot ROM is dc_boot.bin or dc_bios.bin,
the flash is dc_nvmem.bin, arcade platforms read no flat boot ROM, the
system font is compiled in, and NAOMI 2 and System SP load naomi2.zip
and segasp.zip. Archive members carry the CRC the loader looks up.
Each MT-32 entry cites the SHA-1 line and the ROMInfo line of one
mt32emu.h. dosbox_pure wrote them under two repository words, so the
ROMInfo line was self-checked alone and read MOVED onto the SHA-1 line.
Both now sit in the port that carries the file, and in the upstream for
dosbox-pure-unleashed, whose tree has no src/gui.
A recale that lands on a line a sibling part already cites goes to
review, and a part settled by its anchor keeps that anchor's repository.
DecideNAND (MelonDS.cs:684-706) keeps, for a DSi title, only the NAND
slots whose bit is set in header byte 0x1B0. The six DSi_Nand entries
now carry that territory, so --region keeps one 240 MB image, not six.
AUS answers oceania, as every other Australian slot does.
The buildbot serves nicaiemu_libretro (frozen at 4c9b73f7, last built
2026-10-16 05:15) beside coolbaremu_libretro. They are two builds: each
reads its own orientation list from the system directory, so both
profiles stay, each with its own core name. Both read the same .cbe
archives from the same workspace, which builds a standalone binary at
both revisions: one system id and one build type for the two.
Pin moves to 2de3bf8 (v8.4.2). roms/aros-ext.bin, roms/aros-rom.bin and whdboot/game-data/whdload_db.json changed upstream and are collected at that revision. The WHDLoad database is matched on the archive SHA1 first and refreshed from the bundled copy when newer. kick02019.AROS and its .ext are names the Recalbox launcher writes, so the profile now documents the kickstart_rom_file settings instead.
Pins move to libretro/hatari 5092994 and hatari/hatari 90949cf. The port now reads floppy.raw from the system directory (floppy_sound.c:146-186), documented as an optional user sample. Upstream decodes IPF without capsimage, the icon block moved by four lines, and the launcher file names leave the tos.img note for the platform layer.
The Dolphin Sys, PPSSPP assets and blueMSX trees stay required, and the
profiles now cite why. blueMSX finds no machine without Machines/, the
C-BIOS ones included, and the load fails (Src/Board/Machine.c:637-656,
libretro.c:1447-1449). Its tree reference cited libretro.c:1119-1120,
which at the pinned revision is the Sunrise IDE option, and now cites
1196-1197. PPSSPP has no internal font without flash0/font, so
sceFontOpen fails for games using the system fonts
(Core/HLE/sceFont.cpp:805-864, 984-986). Dolphin loads no GameCube font
without Sys/GC/ or an IPL dump and warns that games may crash
(Source/Core/Core/HW/EXI/EXI_DeviceIPL.cpp:328-340).
FirmwareDatabase.cs:405-410 declares NDS+NAND_JPN, EUR, USA, AUS, CHN
and KOR, each with a placeholder hash and 251658240 + 64 bytes. In DSi
mode DecideNAND takes the first one set, limited to the regions a
DSi-enhanced header allows, and stops the load with none
(MelonDS.cs:114, 304, 484, 684-706). DSi mode is off by default, so the
entries are optional, like DSi_Firmware.bin and the DSi BIOS slots.
A missing extended ROM only raises a notice (memory.cpp:1833-1849), but
the machine then runs on the Kickstart alone. cdstrap, cd.device,
cdtv.device and cdfs.library are resident modules of the CD32 and CDTV
extended ROMs and absent from their Kickstarts, the CD32 and base CDTV
models have no floppy drive (cfgfile.cpp:9375-9379, 9405-9406), so no CD
is read or booted. Both entries stay required. The AROS replacement
stands in only for a missing Kickstart (memory.cpp:3055-3063), so the
CDTV entry loses hle_fallback.
FreeIntv declared no data tree while its alias freeintv_ts_overlay,
the same code, declared freeintv_overlays. The core reads
freeintv_overlays/<rom>.png only with the multi-screen option and draws
its embedded keypad image without one (src/libretro.c:278-280, 294,
321-325), so the tree is optional. A test holds every alias to the trees
of its core.
Each core picks its US image for a disc licensed by Sony Computer
Entertainment America, and DuckStation, SwanStation and Beetle PSX
also for a disc whose region they cannot read. Tagged north-america
alone, a --region brazil,jp pack withdrew those images.
Every entry took its names from RetroBat's Uae.Generator.cs, which
the RetroBat launchers: records already hold. Kickstarts are now
labels of the ROM scan, and kick.rom, the name the loader opens under
its data path, is listed.
CheckCdrom sets PSX_REGION_US before it reads the licence, and only
"Inc." or "Euro pe" move it (libpcsxcore/misc.c:422-453). A Latin
American disc boots the US slot, so its four BIOS images carry
latin-america and --region br,jp keeps them.
BlastEm and Kega Fusion pick the European Mega CD BIOS for every disc
whose region code is the PAL one, Australian discs included: BlastEm
reads E or bit 8 of the header region (romdb.c:176-215), Fusion the
security byte 0x64 at 0x20B. Both now carry oceania, and a repo-wide
test holds every European Mega CD BIOS to it.
Fusion picks its export Master System BIOS from the CountryOrder
setting or a CRC32 list, never from the cart, so bios_U.sms and
bios_E.sms carry no region.
kick02019.AROS and its .ext were Recalbox configgen names, shipped at
the BIOS root of four packs whose code never opens them. Recalbox
keeps them through its own amiga/bios declarations. amiga-os-310.rom
is a ROM scan label, now found_by content.
BizHawk finds firmware by SHA-1 scan or a user specification, so the
profile is found_by content. 38 entries used the names RetroBat's
generator writes; they now carry FirmwareDatabase.cs recommended
names, and the pooled NDS firmware entry is split per option.
8dc485dc moved the TOS names into each platform's launchers: records,
but the tos.img notes still described the Batocera, Recalbox and
RetroBat generators and an aliases field the entry no longer has.
The three data package notes cited Batocera's sonic3-air.mk:40, a
package recipe outside the declared repository, so profile_sync
reported it absent for good. The engine data note now cites
EngineMain.cpp by its full path.
HiscoreInit opens <g_save_dir>/hiscore.dat (hiscore.cpp:411). Without
load_from the entry was packed at bios/hiscore.dat and took the slot
mame2000 reads on RetroDECK, which now gets its sha1-pinned file.
Ten notes and comments called .info entries phantom, misleading or
incorrectly written. They now say what the .info declares and what
the code reads, and a prose test refuses those verdicts in profiles.
The repository was renamed to CoolbarEmu (PR #78) and its buildbot
recipe now builds coolbaremu. Hold the profile on 4c9b73f7, the last
revision built as nicaiemu, and document the orientation list it reads
from the system directory.
The Required packs and manifests carried every data tree, the FreeIntv
overlays included. A data_directories entry now accepts required: false,
and the platform, emulator and manifest walks leave such a tree out under
--required-only. FreeIntv reads its overlays only with the multi-screen
option and draws a placeholder keypad without one (src/libretro.c:294-296,
350-369).
The 43 tos.img aliases in hatari.yml and 10 in hatarib.yml were names Batocera, Recalbox and RetroBat launchers pass to Hatari (hatariGenerator.py, Hatari.Generator.cs, libretroCores.py), now recorded in each platform's launchers: records. With standalone Hatari profiled, those records attach. Measured on Batocera, RetroBat, Recalbox, ROCKNIX and RetroPie: verify statuses, manifest files, omissions and Hatari entries are identical before and after.
Batocera (v2.6.1, hatari.mk), RetroBat (v2.4.1 release), Recalbox and ROCKNIX run standalone Hatari, which the profile did not describe, so their launcher records had no build to attach to. Standalone Hatari reads tos.img from its data directory by default (src/configuration.c:810-812, src/paths.c:316-330), retries a missing name with .img, .rom and .tos (src/file.c:275-308, 481-520), and exits when no TOS loads (src/main.c:191-201). The profile is now standalone + libretro, with the keymap file and the window icon as standalone entries and BOOT.ST scoped to libretro.
apple2gs1.rom and apple2gs3.rom come only from Recalbox's gsplusGenerator.py:107-110, 140, a platform launcher now recorded in platforms/recalbox.yml. No platform resolves gsplus.yml (Recalbox, Batocera and RetroBat run gsplus-legacy), and verify and the manifests of Recalbox, RetroDECK, ROCKNIX and EmuDeck are identical before and after.
RetroPie builds minivmac/minivmac, winterheart/quasi88 and TurtleBazooka/px68k under the package names minivmac, quasi88 and px68k (scriptmodules/emulators/minivmac.sh:12, quasi88.sh:12, px68k.sh:12). With built_by retropie and those names in cores, RetroPie resolves them to minivmac37, quasi88kai and px68k-sdl, while its libretro builds stay reached through retroarch. Measured: RetroPie keeps 532 of 532 platform files OK and gains the 14 files the standalone builds read; no other platform's resolution changes.
RetroBat's ares launcher tries v1.05, v1.02 then v1.01 (Ares.Generator.cs:371-437), now recorded under launchers: in platforms/retrobat.yml. ares itself identifies the image by sha256. No file carries the name, so the database is unchanged.
The profile was pinned at 427556b5 (2.11) while the platform transcribes 2.11.1. In 2.11.1 FirmwareDatabase.cs rates one option per slot Ideal (MCD_eu_100, MCD_jp_100p, SCD_m1_us_110, SMS v1.3, gbaNormal and others), adds TI83_110.rom and a doom2.wad slot (DSDA.cs:85-99), and resizes the TI-83 Plus ROMs. The Ideal option of each slot is the required one, refs into the 12 changed files are remapped, and the 40 firmware files 2.11.1 names that the collection lacked are collected, each sha1-verified (LA_us_102.bin matches No-Intro [BIOS] LaserActive (USA) (v1.02)).
Recalbox builds digarok/gsplus-legacy-archive (gsplus.mk:8-9), Batocera a fork of it whose loading code matches, and RetroBat runs its gsplus-win-sdl release (GsPlus.Generator.cs:26-30). digarok/gsplus, which gsplus.yml documents, is a later KEGS 1.38 import sharing no history with it. The legacy build reads ROM, ROM1, ROM3, ROM01, ROM03, ROM.01, ROM.03 at 128 or 256 KB (src/config.c:863-908), refuses to start without one, and reads c600.rom, parallel.rom and printer fonts as optional.
DuckStation (bios.cpp:208, 397-427), SwanStation (host_interface.cpp:
136-194), rustation (lib.rs:107-160), FS-UAE (rommgr.cpp:92-151),
ares (firmware.cpp:116-136) and Altirra (uifirmwarescan.cpp:29-113)
scan a folder and identify firmware by hash; Ymir does in its
standalone build only. FS-UAE still opens rom.key by name
(rommgr.cpp:1397-1498). The export then stops writing their labels
into platform lists: Batocera's psx block goes from 106 entries to 10,
and System.dat's scph5000.bin keeps its own hashes.
Entries without a system in multi-system profiles were left unattributed by the truth model, and four System.dat additions left the export. Each system is read from the core's code at its pin. hiscore.dat, cheats and history serve every running machine (mame2000 cpuintrf.c:664-666, mame2003 cpuexec.c:280-282, mame2003_plus cpuexec.c:296-298, fbneo hiscore.cpp:154-161 gated on BDF_HISCORE_SUPPORTED), all arcade in those builds, so arcade. BIOS sets take the id their driver gives in the other MAME profiles, and bctvidbs is barcrest-mpu4 everywhere. Files serving several systems of one build (groovymame data files, raine) keep no system. Core resolution is unchanged on every platform.
Generated by mame_hash_scraper --devices from mame0289lx.zip, the release asset whose sha256 matches GitHub's digest. Each set is optional: the core runs without it, and only a machine using the device needs it. 1,252 cite their ROM block, two are written without a ref because two blocks hold the same ROMs. Two note citations now carry their full upstream path.
IPL search order iplrom, iplromxv, iplromco, iplrom30 and font cgrom30, cgrom30.tmp, cgrom, cgrom.tmp (SDL/SDL2/winx68k.cpp:277-331), SCSI ROMs (:140-271), all from $HOME/.keropi (SDL/prop.c:172-194). One IPL and one font are required: without them the CPU loop never starts.
The ROM list is src/memory.cpp:87-100. A missing ROM is filled with 0xFF and the emulator starts, so only N88.ROM, N88SUB.ROM and N88EXT0.ROM, without which nothing boots, are required. The directory is QUASI88_ROM_DIR, else <home>/rom (src/file-op.cpp:444-521). The CMake ROMDIR setting only appears in the help text.
The SDL build reads vMac.ROM, fixed at build time to the Mac Plus ROM name and 128 KB (setup/SPCNFGAP.i:60-63), and checks it against three Mac Plus checksums (src/CONTROLM.h:1344-1388). Search order: --rom, the executable's directory, mnvm_rom/ under the SDL pref path, the working directory (src/OSGLUSDL.c:546-620).
load_pac_bios runs only for .mmi content (platforms/libretro/libretro.cpp:507, 521-522), so pac-n1, pce-lp1 and pac-n10 carry system laseractive, and the system cards nec-pc-engine-cd.
o2em_bios defaults to o2rom.bin and only the chosen file is opened (libretro_core_options.h:52-64, libretro.c:989). Loading fails when it is missing or under 1024 bytes (libretro.c:160-189, 1043-1044). The four files share a variant group, o2rom.bin stays required, the others are optional. Only the first 1024 bytes are read and an unknown CRC still loads, so size becomes min_size and crc32 leaves validation.
hiscore.dat and cheat.zip serve every machine (machine.c:361-363), so arcade. The other twenty BIOS sets take the system ids the other MAME profiles give the same sets, from their drivers (naomi.c:4654-4661 for hod2bios, f355bios, airlbios). mac2bios is declared in macs.c:514, 740, not suprnova.c.
The profile set no system on its entries, so the truth model filed every one under the only profile system a platform has (nec-pc-98 on Batocera, truth.py:487-499). system.rom boots only on PCjr (dos_programs.cpp:2995-2996), MIDI ROMs and SoundFonts serve every machine (mpu401.cpp:678-793), FONT.ROM and the PC-98 bitmaps serve PC-98, the VGA and ROM BASIC images serve the IBM PC. The system BIOS image boots either kind and keeps no system.
A Pentagon, Pentagon 512/1024 or Scorpion reset returns an error when a ROM is missing (fuse/machines/pentagon.c:131-139, pentagon512.c:76-91, pentagon1024.c:72-87, scorpion.c:76-78), machine_select_machine fails (fuse/machine.c:237) and machine_select falls back to the built-in 48K machine (fuse/machine.c:150-162). The core keeps running, so the eight model ROMs are optional.
