Each core picks its US image for a disc licensed by Sony Computer
Entertainment America, and DuckStation, SwanStation and Beetle PSX
also for a disc whose region they cannot read. Tagged north-america
alone, a --region brazil,jp pack withdrew those images.
kronos tags the ST-V BIOS epr-19854.ic8 taiwan, mednafen_stv tags it
asia-ntsc, the SMPC area Mednafen names for Taiwan (ss.cpp:1119,
2363-2364). As siblings under asia they never matched, so a request in
one spelling dropped the file tagged in the other, and --region
taiwan,us dropped the Saturn sega_101.bin. AREA_TERRITORIES relates
each area to the territory it serves, china for asia-pal included, in
region.py and its installer copy.
CheckCdrom sets PSX_REGION_US before it reads the licence, and only
"Inc." or "Euro pe" move it (libpcsxcore/misc.c:422-453). A Latin
American disc boots the US slot, so its four BIOS images carry
latin-america and --region br,jp keeps them.
BlastEm and Kega Fusion pick the European Mega CD BIOS for every disc
whose region code is the PAL one, Australian discs included: BlastEm
reads E or bit 8 of the header region (romdb.c:176-215), Fusion the
security byte 0x64 at 0x20B. Both now carry oceania, and a repo-wide
test holds every European Mega CD BIOS to it.
Fusion picks its export Master System BIOS from the CountryOrder
setting or a CRC32 list, never from the cart, so bios_U.sms and
bios_E.sms carry no region.
simple64 picks the PAL PIF for the European and Australian country codes, and New Zealand carts carry one of them. Citra MMJ's AUS font archives serve the region sold in Australia and New Zealand alike. Tagged australia, a leaf New Zealand is not under, --region new-zealand dropped them. They are tagged oceania, as every other PAL file is.
jgenesis picks it for GenesisRegion::Americas, md-emu for boot byte 0x7a, ares for an NTSC-U disc: one code for every disc of the Americas, Brazilian Tec Toy releases included. The three tagged it north-america alone, so --region brazil dropped the BIOS those discs need. genesis_plus_gx and picodrive already carried both.
Profiles, the wiki, comments, docstrings, command output and schema descriptions carried em-dashes, clause-joining semicolons, unicode arrows, box-drawing banners and check-mark glyphs. Each sentence was rewritten rather than having its character swapped. Hashes, paths, source_ref values and every cited file:line are unchanged, which a comparison of each parsed profile against the previous revision confirms.
validate_pr comments now say PASS and FAIL in words, and source_ref values in a profile's structured blocks render as code. test_prose_style fails if any of these comes back, in tracked files or in the generated site.
GC/EUR/IPL.bin fell through to its bare name and the union of five regions, so a Batocera or standalone Dolphin pack never reduced it. The GameCube IPLs of four Dolphin-family profiles now name their system, as the MMJR profiles do.
Emulator mode reduced region groups without knowing which files the
collection holds, so a requested-region image nobody had collected
withdrew the held one and left the slot empty. Platform mode already
kept it; both emulator readers now pass the database.
Region filtering ranked every declared file, held or not, so a request
answered only by a missing file dropped the held fallback and emptied
the slot. Only held files now decide what gives way; the missing better
match stays reported.
Dolphin files the Australian country code under Region::PAL, whose
IPL lives in GC/EUR. Tagged europe alone, --region australia dropped
it and kept the American IPL, which Dolphin never reads for those
discs.
The builder and the coverage report each grouped their own candidates
before asking which regional alternatives to withdraw. The builder
grouped the platform files and the core extras; the report grouped the
platform files alone, and keyed them on an unsanitized destination.
So a region run withdrew 73 files from a recalbox pack while the report
withdrew 14, and described the other 59 as covered by a pack that would
not carry them.
platform_region_groups builds the grouping once and both sides read it.
The extras it returns are keyed by emulator, name and path: Dolphin
declares three IPL.bin that differ by path alone, and a name-keyed map
withdraws the wrong one. Manifests are byte-identical before and after.
