Add and reorder BIOS path entries in the site generator (BizHawk, EmuDeck, RetroPie, RomM). Update the add-platform pipeline steps and CI workflow notes. Document verification behavior changes: FirmwareDatabase index now includes sha256; RomM uses MD5 verification (verify.py checks MD5 only); BizHawk uses SHA1; severity label for GREEN adjusted to WARNING. Clarify troubleshooting/verify output semantics (UNTESTED and mismatch reporting), add profiling fields (core_classification option and adler32), fix several path and link typos (RetroDECK path, README/CONTRIBUTING links), and other small docs polishing.
SwanStation accepts PS1 (512KB), PS2 (4MB), and PS3 (0x3E66F0)
BIOS sizes but only uses the first 512KB. MD5 validates the
extracted content, not the full file. List all accepted sizes
to eliminate the false size mismatch discrepancy.
validation.py: support size as list in emulator profiles.
generate_site.py: handle list sizes in emulator page display.
All 18 original hash mismatches are now resolved: 0 discrepancies.
scph3000.bin v2.1J and scph3500.bin v2.2J already existed under
different primary names (scph3500.bin and scph5000.bin respectively).
Add .variants/ entries so by_name resolves both filenames.
verify_single_emulator now calls _find_best_variant on hash mismatch,
matching the platform-level verification path.
generate_db: add by_sha256 index for O(1) variant lookup.
verify: _find_best_variant uses indexed sha256 instead of O(n) scan.
validation: check_file_validation returns (reason, emulators) tuple,
attributing mismatch only to emulators whose check actually failed.
beetle_psx: remove incorrect size field for ps1_rom.bin (code does
not validate size, swanstation is sole size authority).
Dolphin computes adler32 on byte-swapped (16-bit) data, not raw
file bytes. Add adler32_byteswap flag to dolphin/primehack/ishiiruka
profiles and support it in validation.py.
Reduces hash mismatch discrepancies from 18 to 2.
_find_best_variant now searches by hash (md5, sha1, crc32, sha256)
across the entire database instead of only by filename. Finds
variants stored under different names (e.g. eu_mcd2_9306.bin for
bios_CD_E.bin, scph1001_v20.bin for scph1001.bin).
verify_entry_existence now also calls _find_best_variant to
suppress discrepancies when a matching variant exists in the repo.
Reduces false discrepancies from 22 to 11 (4 unique files where
the variant genuinely does not exist in the repo).
Single source of truth for gap page: verification status from
verify.py (verified/untested/missing/mismatch), file provenance
from cross_reference (bios/data/large_file/missing).
cross_reference.py: _find_in_repo -> _resolve_source returning
source category, stop skipping storage: release/large_file,
add by_path_suffix lookup, all_declared param for global check.
generate_site.py: gap page now shows verification by platform,
18 hash mismatches, and core complement with provenance breakdown.
find_undeclared_files was enriching declared_names with DB aliases,
filtering core extras that were never packed by Phase 1 under that
name. Pass strict YAML names to _collect_emulator_extras so alias-
only files (dc_bios.bin, amiga-os-310-a1200.rom, scph102.bin, etc.)
get packed at the emulator's expected path. Also fix truth mode
output message and --all-variants --verify-packs quick-exit bypass.
