level2/3/4/4P.rom are the TRS-80 Model I, III, 4 and 4P ROMs (groovymame names two by hash) and sat under Mattel/Intellivision. dedup.py removes ten byte-identical MAME archives and records them in the clone map.
The recipe check now fails on a single member outside every recipe of the
archive's name. 29 unpinned archives held one or two such members.
Device sets never have their sub-devices looked up in their own archive:
a device searches its own name, then the system's (device_t::searchpath,
src/emu/device.cpp:140-152). bbc_tube_a500, bbc_tube_a500d and sw1000xg are
rebuilt as TorrentZip from the mame profile recipe. The Arcade/ copies of
a2diskiing, a2mouse, coco_fdc_v11, hp82937, hp98034, pc8001 and mz80k go:
their recipe build already exists under the same name.
In a system set, a device ROM is found in the machine's archive: SAA5050
in bbcm, DragonDOS (default cartridge) in dragon32/64, PC-80S31 in
pc6001mk2sr and pc8001mk2sr. Those are listed as device ROMs in the test.
trs80.zip and trs80m3.zip are rebuilt from the mame recipe; level2.rom and
8041730.u12 stay held loose. The Arcade/ copies of trs80, dragon64 (with a
nested dragon32.zip), pcw9512 and tvc64, and the bk0010 variant, go: every
member is held elsewhere, the only bytes dropped being the empty tmctv
marker of a platform pack.
cvs.zip and aquarius_ar.zip become their recipe builds; the originals move
verbatim to .variants/ for cvs.txt (mame.dk banner) and TMCTV.png, held
nowhere else. The cvs build equals the old .variants/cvs.zip.95581230.
dc.zip (dc_boot.bin, dc_flash.bin) is not MAME's dc set and the bbcb
variant is MAME 0.150's
set; both stay, named in the test.
svg_bios.u49 is listed in svgpcbBIOSRomDesc (d_pgm.cpp:923-929), which only
STDROMPICKEXT(svgpcb, svgpcb, svgpcbBIOS) at line 7035 pulls in. The FBNeo
DAT likewise places it in svgpcb, and pgm's own list (pgmRomDesc, lines
879-892) has six members. The fbneo profile now files it under svgpcb.zip.
bios/Arcade/Arcade/pgm.zip is rebuilt as TorrentZip from the six members of
the FBNeo pgm recipe. The build is byte for byte the copy that was in
.variants/pgm.zip.6bbbce09, which goes. The two unpinned seven-member
copies (.variants/pgm.zip.931a4971 and MAME/.variants/pgm.zip.6ade4934)
go too: every member is still held, svg_bios.u49 as
bios/Arcade/FBNeo/svg_bios.u49. The pinned copies (87cc944e in MAME/,
68ef99a1 in .variants/) are untouched.
RetroDECK pins the container md5 of 170 of the archives 6ee162f8 imported, which carry the ROMs of every slot option reachable from the set. Those copies move verbatim to .variants/, where the md5 still resolves them, and the primary is rebuilt as TorrentZip from the recipe the profiles declare, each member checked by crc32 and sha1. Where a same-named copy in bios/Arcade/Arcade held the same pollution, it is rebuilt too.
Two members only these copies held stay in the older recipe that names them: pio_a72.bin in imds2ioc and presap2rb_123.rom in electron_romboxp (MAME 0.195 to 0.220), both under .variants/.
6ee162f8 imported MAME device and machine archives that each carried the ROMs of every slot option reachable from the set (H19 terminal ROMs in sys68k_cpu30.zip, 371 ISA card ROMs in slvrball.zip). MAME reads a slot card from the card's own archive, so those members were never read there.
Each archive is rebuilt as TorrentZip from the recipe its profiles declare (their union when profiles of several MAME versions differ), every member checked by crc32 and sha1. A copy whose recipe build already exists under the same name is removed, keeping the one filed under its manufacturer. 341-0057.bin, held only in these copies, stays in the MAME 0.220 a2pic recipe under .variants/. Every member removed is still held elsewhere in the collection.
Each profile's contents list names one version of a MAME, AdvanceMAME,
FBA or MAME4droid set. MAME 0.278-0.289 sets come from the archive.org
non-merged romsets; the 0.37b5-0.139 sets are TorrentZip builds of the
listed members, taken from the 0.78 reference set, MAME 0.149 and the
MAME4droid 0.139 romset.
The archive held MAME's galgame set (sw97.lst), not the Galaxy Games
BIOS root galgames (src/mame/ces/galgames.cpp:1301). The new archive
holds the six v1.71/v1.80/v1.90 ROMs, TorrentZip, identical to the
MAME 0.289 romset on archive.org (item mame-0.289).
ROM_START(s8k_cpu) in src/devices/bus/zbi/s8k_cpu.cpp (mamedev f34f0250) names cpu_34-0715-03a.u76, cpu_34-0717-03a.u75 and cpu_34-0718-03a.u77 under two system BIOSes with the same CRC. The archive held them twice. Rebuilt with build_torrentzip from the 13 distinct members, each checked against the mame0289 recipe sha1.
21 device archives collected for MAME 0.289 are byte-identical to sets already held under another name: a set renamed in 0.289 (tms32030 to tms320c30, hardbox to gpib_hardbox) or one ROM set several devices share (sys68k_cpu21 family, voicebox). One copy stays and the other names go to the MAME clone map, through which each name still resolves.
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.
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).
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.
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.
dedup.py removes a copy only when another file has the same SHA-1 and
the same name, keeping the higher-priority path, so resolution by hash
still finds the content. Verified rather than assumed: all 17268
manifest entries ship the same bytes as before, no destination gained
or lost, only the source paths consolidate. Every deleted path's content
is still held elsewhere.
12.1 MB and 48 empty directories go with them. The index and the
published artefacts are regenerated on top.
Four archives carried member names no MAME version uses. Each is decided
against MAME 0.289 at the revision the profiles cite:
manager.zip 1 -> 01 crvision.cpp:957
sys573.zip 700a01(gchgchmp).22g -> , ksys573.cpp:3575
cedmag.zip Magnet-Master-VID-E03.BIN cedar_magnet.cpp:1040
advision.zip b225__/b8223__ prefixes cut advision.cpp:456,459
Content is untouched: every member keeps its crc32 and size. The
archives are rebuilt with torrentzip so their bytes depend only on their
contents, which is the repository convention (51 of 60 sampled archives)
and what two of these four already were.
Batocera, RetroBat and RetroDECK pin the older naming, so the upstream
archives stay verbatim under .variants/ and resolve_local_file serves
each layer the copy it expects.
