Dropping the double-dash asides left 72 comments and docstrings with
half a dash glued to the next word ("shape -a size or a size range -is
all"). They now read as a colon, a comma or parentheses, and a prose
style test names any that comes back.
bundled describes the emulator's own release, and a platform package can differ both ways: Batocera's hcl package installs the binary alone and sends users to fetch the data, while its blueMSX core package copies the machines and databases beside the core. not_bundled_on and installed_on name those platforms, and the builder reads them through one rule.
A file or tree installed with the emulator is already on the user's machine, so packs, install manifests and verify's pack count leave it out. bundled is scoped by mode like any entry: Dolphin's Sys and PPSSPP's assets ship with the standalone releases, not with the libretro cores, so they now follow the libretro build only and still reach RetroArch packs. PrimeHack, standalone only, ships its own Sys.
The integrity step compared a member's md5 by hand and ignored hash_rule, so under RomM's rule (size, then any of md5, sha1 and crc32) it would refuse a revision the builder rightly shipped on its sha1. The rule now lives in digest_verdict, which the path check and the pack member check both call. The member's archive digest is computed without the path cache, whose key a buffer's reused address made collide.
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.
RomM's verify_file_hashes compares the size, then md5, sha1 or crc. We
compared md5 alone, so a fixture entry with one mistyped hash was left out
of the pack RomM would accept it from. The rule is declared in romm.yml
and read by verify, the builder and the manifest.
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.
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.
Run ruff check --fix: remove unused imports (F401), fix f-strings
without placeholders (F541), remove unused variables (F841), fix
duplicate dict key (F601).
Run isort --profile black: normalize import ordering across all files.
Run ruff format: apply consistent formatting (black-compatible) to
all 58 Python files.
3 intentional E402 remain (imports after require_yaml() must execute
after yaml is available).
