dsi_bios7.bin and dsi_bios9.bin hold the DSi Panda devkit boot ROMs, eMMC
key-Y zeroed. Every md5 and crc32 declared under those names designates
a retail dump in the same directory, yet hashless entries (RetroBat,
dsperate) got the devkit ROMs by name. by_proven_name maps such a name to
the proven primaries beside it. kick13.rom, dsi_firmware.bin and
spectrum.zip follow the same rule.
A tarball tree was announced at its extracted size: yaps2 at 6.5 MB for a 21.2 MB download, Cemu's game profiles at 9.9 KB for 21.4 MB. refresh_data_dirs records the size of each archive it downloads (a tree current from before is measured, not refetched), the install lists carry it as archive_size, and the plan, the menu and the data event count it.
PCSX2 stats <bios>.rom1 then <stem>.rom1, case-sensitive on Linux (BiosTools.cpp:214-229), and so does PCSX2 1.6 for erom. The pack wrote the stored SCPH-70004.ROM1, never found. A companion entry also seeded a scan of its own with a 4 MB bound and swept cheats, GameIndex.yaml and DVD firmware to the BIOS root. A companion now scans its image's folder for its own extension only, any size, since the code reads min(size, filesize), and is written as the code spells it.
set5v0.972.ic507 (Katana Set5 v0.972, crc32 1a2f2a91, sha1 08df891f) entered MAME's dcdev set in 0.260. It comes from the archive.org item MAME_0.278_ROMs_non-merged_2025, whose dcdev.zip is the TorrentZip of the 0.260+ recipe. It becomes the primary dcdev.zip, and the five-member pre-0.260 set is kept as a variant.
Demul's dc set (11 rows of demul.exe's table) is built with build_torrentzip from members checked against the table's crc32 and sha1, in bios/Other/demul/. Only Demul reads dc.zip, so only its manifest entries move.
Demul 0.7 reads 44 NAOMI BIOS rows from naomi.zip, the HOTD2, F355 and Airline Pilots BIOS among them. No copy held them all. The set is built with build_torrentzip from members already in the collection, each checked against the crc32 and sha1 of demul.exe's table, and kept in bios/Other/demul/. Batocera, KNULLI and RetroBat place it at bios/naomi.zip, the file MAME cores there also open, so it carries the nine MAME members the Demul table does not list.
The resolver left another emulator's own copy out of the member and superset ranking, so Flycast and the MAME cores keep the copies they were served.
Demul 0.7 build 251220 (demul.exe sha1 e326ae66, the build RetroBat and Batocera 43.1 ship) loads its BIOS from MAME-style sets named in seven tables in the executable: dc, naomi, naomi2, segasp, awbios, hikaru, mie and segadimm, each member checked by size, crc32 and sha1. The profile lists every set with its members and cites the tables and the loader by address. dc_boot.bin, dc_flash.bin, naomigd.zip, hod2bios.zip, f355bios.zip, f355dlx.zip, airlbios.zip and jvs13551.zip are not read by this build and leave the profile.
Fourteen lists gain the data trees their cores read. AmberELEC and EmuELEC fetch the 192 blueMSX machine configs from the tree instead of holding them back, and RetroPie drops the blueMSX tree its lr-bluemsx module installs.
DecideNAND (MelonDS.cs:684-706) reads the JPN, USA, EUR, AUS, CHN and KOR
bits of header byte 0x1B0. A DSi title sold in Latin America carries the
USA bit, so the USA NAND serves it. Tagged north-america alone, it fell
out of an --emulator bizhawk --region br,jp pack.
Genesis Plus GX declares bios_U.sms and bios_E.sms with no hash. Only
.variants/ copies carried those names, so the name step served the Store
Display Unit BIOS and a 256 KB BIOS, while every platform pins v1.3 under
both. Two causes in generate_db: the v1.3 content's path was ZEsarUX's
sms.rom, which the resolver sets aside as another emulator's file, and a
name pinned by hash was refused when only variants carried it.
The scan now prefers a copy filed under its machine over one in an
emulator's own tree, and a name only variants carry can name the content
a hash pins it to.
Manifests: six contents change repo_path only (v1.3 SMS BIOS and five
ZEsarUX Spectrum ROMs, same sha1). On batocera, knulli, recalbox and
retrodeck the Genesis Plus GX bios_E.sms and bios_U.sms extras move from
the two variants to v1.3.
NP2kai and meowPC98 read font.bmp (PC-98 bitmap) and FONT.ROM (V98) as
separate files, each through its own reader (NP2kai font/font.c:192-195,
meowPC98 font/font.c:180-181). The V98 names hung on font.bmp as aliases
let a collection without font.bmp serve the PC-88 2 KB font.rom there.
FONT.ROM is now its own entry, at least 0x46800 bytes (fontv98.c:8, 51).
Manifests: np2/FONT.ROM and np2kai/FONT.ROM are added where the platform
did not declare them, served by the V98 font bios/NEC/PC-98/font.rom.
The resolver now keeps a name inside its own emulator tree and the retail Xbox dashboard files moved to bios/Microsoft/Xbox/C/, so the install lists, README counts, installer samples and games index are rebuilt from the merged tree. Built twice, identical.
Same files per platform. The manifests catch up with the per-system MAME
filing, the platform system join and declared_in, and name sfiii2a.zip as
missing. The games index fallback sets and the installer page samples
follow.
install/<platform>.json wrote the constant "1.0" as the version of the
list it was built from. The manifest now carries the version the platform
YAML records, and generate_pack refuses a YAML without one.
inherits: no longer passes a parent's version to a child: Lakka was
published as RetroArch v1.22.2 in its manifest, pack name and site page.
lakka.yml records v6.1, the Lakka-LibreELEC tag its target list is read
at. The MiSTer scraper refuses a BiosDB without a timestamp instead of
writing an empty version.
A pack's manifest.json records list_version, so an install from the pack
alone knows it too. Manifests regenerated twice and compared: only
version and generated changed.
The copy shipped first was the European MK-80310 Video CD card (its header reads VIDEO CD PLAYER PAL MK-80310, version 1.105). Lunar Silver Star Story MPEG, the Saturn game that needs a card, names the Movie Card, so the Japanese HSS-0119 (V1.102) now leads and the MK-80310 stays as a variant. No emulator tested reads the card's content today (records in measurements/beetle_saturn.jsonl), and no platform pins a hash for this file. Issue 85.
After the second bring-to-head pass: 40 bumps, ten profiles by hand,
five off-forge apps, the G-NET BIOS sets and the new hiscore.dat.
Manifests generated twice, identical.
Core extras placed under the bios prefix are now one claim per path, so
DuckStation's region-tagged PS2 images carry their regions in the
manifests. Generated twice, identical.
After section A of the round 5 audit and the ROCKNIX standalone profiles
(data_root on 58 profiles, 67 display names, three alias folds, 33 core
names mapped, scummvm and vice standalone, yabasanshiro both modes).
Manifests generated twice, identical.
Each manifest carries system_titles, the name the site prints for every system its files list (Sony PlayStation, not sony-playstation or psx), so the installer can show it. Older installers ignore the field.
The three committed samples sat under FBAlpha 2012 while the four
release assets and the profile use fba2012/samples. The folder check
now folds Alpha to A and also reads database paths, which list the
release assets the index never holds.
QEMU's 79 files go to QEMU/QEMU and Roland's four loose ROMs to MT-32
and CM-32L. The mt32-roms, soundcanvas-roms and sounddata trees stay as
the code addresses them. Chihiro joins Sega and the Oric joins
Tangerine, the names the site and libretro already use. No destination
held other bytes.
The three QEMU EDK2 images are release assets, and their .gitignore
lines follow them. Database and manifests are regenerated together.
verify --all and cross_reference give the same output once moved paths
are mapped.
DS and DSi split into Nintendo DS and Nintendo DSi. 64DD, Mega-CD,
ZXSpectrum, VSmile, BBC and Game Engines/DOOM merge into the folder
of the same console. Same-named dumps with other bytes are kept:
BBC Micro's earlier zips in .variants/, the vsmilem set in vsmilem/,
the Doom II 1.666 IWAD in v1.666/, BizHawk's DSi firmware in bizhawk/.
Galaksija and Vircon get a console folder, sdlpal's desc.dat joins
its tree, VICE's PET and CBM-II ROMs leave C128 with their vice/ tail.
Database and manifests regenerated together. Verify and cross
reference give the same result once moved paths are mapped.
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.
55 device sets the collection lacked or held incomplete. 24 are rebuilt from ROMs already in bios/, 31 come from the archive.org item mame-roms-non-merged. Every member matches the 0.289 listxml size, crc32 and sha1, and each archive is built with build_torrentzip. The complete nss_tvinterface goes to .variants since RetroDECK pins the incomplete copy. The old at_keybc.zip held two of the three ROMs, its md5 is pinned by no platform, and is replaced by the complete set RetroDECK pins (63536a7d). Database and install manifests are regenerated with the files, including the vMac.ROM move.
