A hashless profile entry adopted the only exact holder of its name as the file its aliases designate. dosbox's SC-55 ROM2.BIN found Galaksija's ROM2.BIN, and ROM2_ST.BIN was indexed against a 4 KiB BASIC ROM while SC-55's rom2.bin sat under the same folded name. The name now has to designate one file once case is folded, a primary and its own variants counted as one.
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.
AmberELEC's nec-pc-88 declares DISK.ROM with an empty md5. QUASI88 reads
that name as n88sub.rom, the 2 KB PC-88 disk ROM (libretro.c:1085), but
the name step served the 16 KB MSX disk ROM, the only primary of that
name. The quasi88 alias never reached by_name, which refuses an alias a
primary already carries.
load_platform_config now writes each entry's system as platform_system.
A platform entry with no hash and no owning emulator, whose system id
names a maker, takes no name candidate filed under another maker, in
the name step and in the hash_mismatch step after it. When nothing is
left, by_shadowed_alias, the profile aliases by_name refuses, answers
within the system's maker folder. names_manufacturer and BUCKET_FOLDERS
move to common.py, and generate_site imports them.
Across every registered platform the only resolution that moves is
AmberELEC nec-pc-88 DISK.ROM, from bios/Microsoft/MSX/DISK.ROM to
bios/NEC/PC-88/N88SUB.ROM. Manifests, truth and exports are otherwise
byte-identical.
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.
Extracted from the ep128emu ROM package (http://ep128.hu/Emu/ep128emu_roms-2.0.11.bin, sha256 775f65b4...0441) that installer/makecfg.cpp downloads, unpacked with Ep128Emu::decompressData from src/decompm2.cpp and split per the makecfg.cpp table. The ROM identifies as EPIDE version 1.2.
x1-box and hakuX both import the retail partition C tree. It sat in
hakuX's tree, so for x1-box the C/xbox.xtf tail was set aside as foreign
and the name step served Xenia's Xbox 360 dashboard font. xbox.xtf and
xboxdash.xbe now live in bios/Microsoft/Xbox/C/ and resolve by path for
both. msdash.xbe stays: its bytes are cxbx-reloaded's xboxdash.xbe, whose
path the RetroBat manifest names.
redump.info moved its BIOS DAT links from /static/bios/<name>.dat to one
route per system (/bios/PSX, /bios/PS2, /bios/GC, /bios/XBOX), served as
an attachment. The scraper matched only the old shape and found nothing.
Both shapes are read now.
Refreshed snapshot: the PS2 DAT moved from 2026-06-16 to 2026-10-10,
191 entries become 225 (34 mechacon, DVD and font ROMs added, the
ps2-dvd-302c.bin sha1 corrected, five descriptions completed). Only
the provenance fields of database.json change.
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.
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.
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.
A profile entry without a hash matched the collection by name, but
only primary names were looked up, and which copy of identical bytes is
primary follows path order. After the refile, project64's
64DD_IPL_v12_JPN.bin was a copy, so 64dd_ipl_J.bin and 64dd_ipl_U.bin left
the name index. The lookup now counts every copy's name, and a name held
by two contents still names neither.
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.
A file that arrives with the emulator is already on the user's machine
and the packs leave it out. 4558 collected copies (1.4 GB) were reached
only by such entries, with no platform, other profile entry or install
manifest needing them. They are removed, and two release-asset copies
leave the ignore list. bundled_only.py now lists every copy of a listed
file, since the database keeps one path per content, and pipeline step
4d fails while one remains.
Each platform's own packages were read at the revision our data pins, for every emulator and core it ships: Batocera, Recalbox, RetroPie, ROCKNIX, Lakka, RetroDECK, RetroBat and EmuDeck. Files a package installs where the emulator reads them are recorded with installed_on, and files a release bundles but a package leaves out with not_bundled_on, so each platform's pack brings what its users lack and nothing they already have. The standalone profiles never checked before were held against their releases the same way. Batocera's imame4all is the mame2000 core. The primary neogeo.zip was a 7.7 KB placeholder no platform pins and no pack served: removed, the real dumps stay in .variants.
100 emulator names the two platforms run had no profile, so their packs carried nothing for them. Each was read from the platform's own launcher or scriptmodule: the same program as an existing profile takes the name in cores:, a different build gets its own profile read from that version, a launcher or self-contained game goes to remove_cores, and the rest are new profiles written from their source or shipped binary. The files they need that the collection lacked are collected from the upstream distributions. Bungie and splitwolf trees are read by path and stay out of dedup.
6.1.12 no longer bundles ROOT.chts and its seven cheat sets: the cheat browser reads the home folder, then unpacks Downloads/iNES-Cheats.zip. The seven sets are collected from the author-signed 6.1.4 package, each file covered by its signature. Controls.png and the backdrop pictures the app reads are documented.
