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.
Basilisk II opens a file named ROM, checks its size, its version word and the code PatchROM rewrites, and no hash. By name the only candidate was the 128 KB Apple IIGS ROM, which the size gate rejects, so the pack shipped nothing. The collection's mac.rom (Performa/Quadra 630, version 0x067c) passes every gate, and the entry now names it as an alias. KEGS and GSplus keep the IIGS file.
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.
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.
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.
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.
Three refs cited paths under Q3E/src/main/jni that the repository does
not carry: xash3d-fwgs and SeriousSamClassic are git submodules, so the
parent tree holds pointers and nothing else. They read as the separate
repositories they are, which is what the external form is for.
Reading the last two changed blocks turned up the substance.
ETQW_GLSL_SHADER_VERSION went from .3 to .6, and the bundled
zzz_etqwbase.pk4 grew from 136061 to 141815 bytes: the size, md5 and
sha1 the profile recorded describe the pack that was replaced. The new
one is in, the old one kept as a variant for builds that still expect
it, and GameResourceUrl gained two Quake 4 mod entries along the way.
70 refs, 68 anchored and 2 external, none left to read.
LinApple 3.0.0 moved every ROM out of hand-written byte arrays into
res/roms/*.rom, which scripts/generate_roms.sh compiles into
EmbeddedRoms.cpp behind an ENABLE_ROM_* macro. The bytes survived the
move: every hash this profile recorded against the old string literals
matches the image that replaced it.
The macros are what matters. ENABLE_ROM_CLONE_BASE64A,
ENABLE_ROM_CLONE_PRAVETS and ENABLE_ROM_CLONE_TK3000E are OFF in the
default build, so Base64A, Pravets 82/8M/8C and TK-3000 //e refuse to
start: mem_initialize finds no rom_data, names the cmake flag and the
--rom option, and returns -1. Five system ROMs the user has to supply,
none of them documented until now. The collection already held them.
Also new: icon.bmp, which the SDL frontends read from disk through the
data search path, and the J-Plus system ROM the old profile did not
list. The tree behind the old refs is gone, so the notes describe the
one that replaced it: five frontends, src/core, src/apple2, and a
program_dir still declared and never assigned.
38 refs, all anchored. 9 of 9 files present.
