MAME 0.289 reads intv.zip (exec.bin, src/mame/mattel/intv.cpp:549-552)
and videopac.zip (o2bios.rom, src/mame/philips/odyssey2.cpp:902-905).
The collection held both ROMs loose, INTV_EROM.bin and o2rom.bin, with
the crc32 and sha1 MAME declares. The two archives are built from them
with build_torrentzip and filed beside them: bios/Mattel/Intellivision/
and bios/Philips/Videopac/.
odyssey2 is a clone of videopac declaring the same o2bios.rom, which a
ROM search along the parent chain finds in videopac.zip. Its archive
would be a byte-identical copy, so the profile entry is dropped and the
videopac entry says so.
database.json gains the two archives (the name index also follows the
profiles' current aliases), and recipes/archives.json their recipes,
both rebuild: exact, sources profile:mame and collection.
Manifests: intv.zip and videopac.zip reach mame/bios on every platform
running MAME, and roms/intellivision and roms/videopac on EmuDeck and
RetroDECK. Each platform has 2 to 6 fewer omissions.
sfiii2a.zip for FBNeo, the Odin board sets, HyperScan, Basilisk II,
the XM7 and FM-7/X1/PC-88/VideoBrain MiSTer ROMs, the FM Towns ROMs
RetroBat now checks, CD-i vmpega.rom, Apple II card ROMs for POM2, four
Amiga accelerator ROMs, and the no$gba DSi SD image (release asset).
Each file matches a hash its profile or platform declares, or MAME's.
