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.
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.
coco.zip held only bas10.rom, the MAME 0.190 to 0.250 set, while 0.289's coco loads bas10, bas11, bas12, extbas10 and extbas11. The complete set is rebuilt with build_torrentzip from held ROMs plus extbas10.rom (crc32 6111a086) checked against the listxml sha1. The old archive goes to .variants, no platform pins its md5. RetroBat and RetroDECK pin scv.zip without upd1771c-017.s03, which 0.289 requires: the pinned copy stays and the complete set goes to .variants.
