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.
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.
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.
New files: OpenTyrian data (11), Cave Story (2), SeaBIOS,
VGA BIOS, OpenSBI, Cromwell, xbox_hdd, Sega CD Model 2 (3),
NGP Color BIOS, Pentagon 128p-1.rom, X1 font, BK TERAK.
