The primary (sha1 f7101b40) is named by no dump catalog and differs from the catalogued dump in 60 runs of 16 bytes. The variant (sha1 b3b1d880) is the dump No-Intro, TOSEC and MAME 0.289 (laseractj, v105) name and the only one BizHawk 2.11.1 accepts (FirmwareDatabase.cs:294). No platform pins either md5, so the catalogued dump becomes the primary.
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.
Recalbox now resolves uae4all to its own libretro build, so only the bundled entries of the standalone uae4all2 reached these two AROS ROMs, which its release ships.
The libretro core passes system/mame/{hash,plugins,samples} (retro_init.cpp:111-155). Software lists are required in mamemess, where softlists are on by default. The trees and the 19 floppy samples are collected from libretro/mame at the pin.
Seven artwork zips from the core's metadata/artwork are read from mame2003-plus/artwork/ when Display Artwork is on, the default (artwork.c:2242-2258).
The libretro core copies whdboot from the system directory and uses a candidate only when WHDLoad, JST, AmiQuit, boot-data, the game database and the five RTB files are all there (amiberry.cpp:11510-11584). The core zip has none of them, so they are collected.
The A500 and LOUD floppy sound sets are read from uae_data/ (driveclick.c:77-104) when the option picks them, and capsimg is loaded from the system folder for IPF images (caps.c:37-96). The ten samples are collected from the core repository.
Since 3fffeb1 prboom.wad is compiled into the core (d_main.c:1449-1465). The IWADs it searches beside the content, in system/prboom/ and in system/ are now listed, with the ZDoom pk3 loaded before a pk3 mod.
The profile listed none. id1/pak0.pak is required (host.c:711-760), the retail and mission pack paks are read in order until one is missing, and Quoth 2.2 is mounted when the content path names it (common.c:1017-1020, 1724-1725). The three Quoth paks are collected, pak1.pak as a release asset.
The pin (1e0de94d) already loads Sega CD, 32X, ColecoVision and LaserActive firmware from the system directory, and the profile still described the earlier core with no BIOS at all. Each file now carries its code reference, required flag and build. The LaserActive player firmware (uPD78237, 64 KiB) is collected from the dump its author published.
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.
SheepShaver opens ROM or Mac OS ROM, decodes a CHRP-BOOT image and requires a nanokernel ID it knows. By name its entry was served the 128 KB Apple IIGS ROM, which it rejects. Mac OS ROM 1.4 is taken byte for byte from the System Folder of Apple's iMac Software Restore CD 691-2313-A (archive.org, ISO sha1 as listed). Its LZSS payload decodes to 4 MB with the NewWorld nanokernel ID, and a size floor derived from the decoder keeps the IIGS ROM out.
DSperate reads TWLFontTable.dat for DSiWare run without a NAND. The file sits in nand:/sys/ of the DSi NAND dumps the collection holds. Decrypted with the console ID and CID in each dump's nocash footer, as DSperate's own NAND reader does, the four western and Japanese consoles give one table, the Chinese and Korean ones their own: 863296, 581664 and 162688 bytes, the sizes and sha1 already known for them.
POM2 reads nine Virtual ][ sounds from roms/virtual_ii_sons/. All nine are inside VirtualII.dmg from virtualii.com (13.3). The five AIFF files are taken as they are. The four .raw files are signed 16-bit little-endian mono at 44100 Hz, as Virtual ]['s own playback code declares them, and are wrapped in a WAV header, the data chunk being the raw file byte for byte. pom2 verifies 78/78.
Nixie's layouts at vpinball e4a79a5, PinMAME memmaps at tomlogic/pinball-memory-maps 68c1b337 and game definitions at vpinball/pinmame-game-defs 6eece7e5: the subset every platform build copies into third-party/. 1,280 files, each matched to its upstream git blob, documented as three directory entries.
The five native libraries the reprofile added, and the assets and libraries whose copies dated from 1.8.2-open, now come from the official build of 752b93a (release continuous, CI run 39297510978, signing certificate de1bd54d as on 1.8.2). Assets match the repository blobs byte for byte. The profile carries their hashes, and the bundled-identity table now records each fall exactly.
hypseus-singe, flycast-dojo, lindbergh-loader and vvvvvv read gamecontrollerdb.txt without naming a hash. The name step only set aside copies in other emulators' trees, so a copy in a game's folder under Game Engines/ ranked with any neutral one, and index order handed them C-Dogs' 98-line database. A game folder's copy now ranks after a neutral copy. The community SDL_GameControllerDB is collected at commit ff333823 (git blob 25146be7) as that neutral copy.
PCSX2x6 reads bin/resources/GameIndex.yaml, an arcade database keyed by NM gameid. The shortened tail resources/GameIndex.yaml matched four files, and the resolver set aside the three in other emulators' trees before measuring ambiguity, so PCSX2's console database passed for path proof and shipped in the PCSX2x6 pack. Ambiguity is now read before that filtering. A tail indexed from an identical copy is kept even when the database records the other copy's path.
PCSX2x6's GameIndex.yaml and RedumpDatabase.yaml are collected from its repository at the pinned 583f0e90 (git blobs ed8232e3 and 8669b3af).
Upstream compiles Opera Boot into the core as the default BIOS and reads opera-boot.bin from the system directory. Every retail BIOS becomes optional; opera-boot.bin is collected from the opera-boot release, identical to the embedded image.
The LaserActive v1.05 variant read WONDER-MEGA BOOTROM 1.00W at 0x100, as No-Intro and TOSEC name it. It moves to the Mega CD tree and the catalogued v1.05 (md5 927df773) takes its place.
The new-format hiscore.dat was served by name to cores whose parser reads
only legacy lines. Eight cores now pin the hiscore.dat their own
repository ships, four revisions newly collected.
System.dat pins the 2 KiB X1 font as xmil/IPLROM.X1T, where xmil reads
a 32 KiB Turbo IPL. A held copy of the exact size a profile declares now
proves its claim against a file of another size, so the existence packs
ship the IPL. The font's duplicate under the IPL name is removed.
It was the SCPH-70004 v12 ROM2 under a Galaksija name, kept only because
System.dat gives Galaksija's ROM2.BIN that hash. ROCKNIX installed it as a
stray ROM2.BIN; it now gets the dump under the name its BIOS pairs with.
The standalone b2 loads its machine ROMs from assets/roms; the profile
declared none because the libretro port embeds them. 44 entries from
tom-seddon/b2 e1c9b84, 31 ROMs collected, 12 already held.
The profile documents BAM 1.5-408 but the collection held the
1.5-360 BAM.dll and renderingengine.dll, served by name. ravarcade
still serves BAM_v1.5-408.zip; its two DLLs become the primaries,
with hashes, and the 1.5-360 builds stay as variants.
The entry documents the 0.29 notes and declared no hash, so the
0.23 notes in the C-BIOS machine folder were served by name. The
file comes from MSX.emu's res/firmware at the profile's pin.
A copy under .variants/ exists to hold a content its primary does
not. 29 held bytes another file already carried, under a second or
third identity: msx.rom and MSX.ROM variants equal to
MSX_8020-20bios.rom, naomi2.zip.da79eca4 whose suffix named the
primary's sha1 rather than its own. dedup now removes such a copy,
keeping one when only variants hold the content. The LaserActive
PAC-S10 BIOS lived only under .variants/ while RetroBat names it
without a hash; it moves beside its siblings.
The four MT-32 and CM-32L ROMs had a second copy in the Amiga
tree, and the identity exemption that hid the crossing named a
DOSBox tree instead. The copies move next to the Munt ROMs already
under Roland, and each exemption now names the makers it covers,
so a copy under a third one is reported.
ROCKNIX builds a different emulator set per SoC, and without a target
list an H700 handheld received the PS2, PS3 and GameCube firmware of
emulators its image lacks. The new target scraper reads the emulators
metapackage per device; seven cores ROCKNIX ships get profiles and the
Super Famicom Box ROMs one of them needs are collected.
RetroArch pins 23 ScummVM engine-data files and FBNeo's hiscore.dat at
revisions upstream history still holds; they are now collected. The
two profiles claim the revision their core is built from, so the pack
keeps serving the core its own files and the pins sit beside them.
Batocera 43.1 ships vkQuake, vkQuake2, vkQuake3 and a Supermodel held
at 0eef09ba for the Raspberry Pi 4; none had a profile, so a targeted
pack dropped them. Each profile is read from the commit Batocera
builds. Collected with them: the Quake 1.06 id1/pak0.pak, the same file
in the shareware and registered releases, and the Games.xml that
Supermodel revision installs.
Recalbox checks geolith/neocd.zip by the composite md5 of its members,
which is front-sp1.bin then top-sp1.bin: the Front and Top Loader
BIOS geolith reads inside neocd.zip, both already collected. The
archive is rebuilt as a TorrentZip variant and Recalbox's last
missing BIOS resolves.
