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.
naomi_roms.h opens each BIOS archive member by filename, one per
region. Without the names, a copy of hod2bios.zip lacking
epr-21329.ic27 counted as the archive and Japan games had no BIOS.
The name step only ranked archive copies by members declared
through archive sub-entries, and the contents an archive entry lists
never reached the resolver, so the first copy indexed won. contents
now ranks copies by crc32, or by member name where the code opens
by name, and the report and both extra passes carry it. With no
layout declared, a primary holding every ROM of the others wins;
two revisions keep the index order.
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.
generate_pack kept a private .gitignore parser whose cache ignored the
root it was asked about, and generate_db a copy of the shared one. Both
now read largefiles.load_registered_paths, cached per root. Test modules
whose main block preceded their last class end with it again.
Batocera, ROCKNIX and Recalbox find a file through the core that wants
it. Additions now carry that core under the platform's own name: the
emulator/core pair checkBios reads (ROCKNIX's from its emulators
package), or Recalbox's core attribute. One with no nameable core, or
filed in a system gated on another core, is counted as not stated.
