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.
Source: Subtixx/RetroStation MSX2J.rom
SHA256 0c672d86 matches ares desktop-ui/emulator/msx2.cpp:15.
Resolves last MSX2.ROM discrepancy across all platforms.
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.
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).
Update wiki source files (the single source of truth for the site):
- tools.md: renumber pipeline steps 1-8, add step 6 (pack integrity),
add missing CLI flags for cross_reference.py and refresh_data_dirs.py
- architecture.md: update mermaid diagram with pack integrity step,
fix test file count (5 files, 249 tests)
- testing-guide.md: add test_pack_integrity section, add step 5 to
verification discipline checklist
Remove 4 unused functions from generate_site.py (generate_wiki_index,
generate_wiki_architecture, generate_wiki_tools, generate_wiki_profiling)
that contained stale data. Wiki pages are sourced from wiki/ directory.
Update generate_site.py contributing section with correct test counts
(249 total, 186 E2E, 8 pack integrity) and pack integrity documentation.
Move verification logic to generate_pack.py --verify-packs (single
source of truth). test_pack_integrity.py is now a thin wrapper that
calls the CLI. Pipeline step 6/8 uses the same CLI entry point.
Renumber all pipeline steps 1-8 (was skipping from 5 to 8/9).
Update generate_site.py with pack integrity test documentation.
Extract each platform ZIP to tmp/ (real filesystem, not /tmp tmpfs)
and verify every declared file exists at the correct path with the
correct hash per the platform's native verification mode.
Handles ZIP inner content verification (checkInsideZip, md5_composite,
inner ROM MD5) and path collision deduplication.
Integrated as pipeline step 6/8. Renumber all pipeline steps to be
sequential (was skipping from 5 to 8).
RetroDECK: core extras with subdirectory paths (e.g. vice/C64/,
fbneo/, dc/) were placed outside bios/ because the prefix was only
inferred for bare filenames. Add _detect_extras_prefix() to infer
the dominant BIOS prefix from YAML destinations.
RomM: core extras landed flat at bios/{file} instead of the required
bios/{platform_slug}/{file}. Add _detect_slug_structure() to detect
per-system slug layouts and _map_emulator_to_slug() to route each
extra to the correct slug subfolder.
Also skip manifest writes when only the generated timestamp changed,
preventing unnecessary diffs in install/*.json.
Closes#43
FBNeo and Kronos expect BIOS archives in core-specific subdirectories
(system/fbneo/, system/kronos/). RetroArch firmware check uses .info
paths which include these prefixes, so files at root show as Missing.
Add archive_prefix field to emulator profiles. The pack code now places
archive copies in the prefixed subdirectory while keeping root copies
for cores that expect them there (e.g. Geolith for neogeo.zip).

auto-fetched from mamedev/mame 0.287 and finalburnneo/FBNeo v1.0.0.2.
mame: +20 new BIOS root sets, 96 entries enriched with contents.
mamearcade: 47 entries enriched with contents.
mamemess: 20 entries enriched with contents.
fbneo: +13 new ROM entries from upstream BIOS sets.
replace yaml.dump with surgical text edits for contents/source_ref.
preserves comments, block scalars, quoting, indentation.
fix FBNeo new entry detection using parsed keys instead of text search.
sparse clone upstream repos, parse BIOS root sets from C source,
cache as JSON, merge into emulator profiles with backup.
covers macro expansion, version detection, subset profile protection.
write_if_changed in common.py compares content after stripping
timestamps (generated_at, Auto-generated on, Generated on).
applied to generate_db, generate_readme, generate_site.
eliminates timestamp-only diffs in database.json, README.md,
mkdocs.yml, and 423 docs pages.
bios_mode: agnostic (profile) and agnostic: true (file) for
emulators that accept any valid BIOS without specific filename.
find_undeclared_files skips agnostic entries, pack extras scan
includes all matching DB files by path prefix + size criteria,
resolve_local_file has agnostic fallback with rename README.
applied to pcsx2, lrps2 (bios_mode), melonds dsi_nand (file).
aliases must be same-SHA1 alternative names, not distinct files.
pcsx2: 164 different BIOS dumps are separate DB entries, not aliases.
melonds: 6 regional NAND dumps are separate DB entries, not aliases.
also cleans pcsx2 non-standard fields, fixes display_name.
expand_platform_declared_names resolves platform file MD5s
through the database to recover canonical names and aliases,
eliminating false positive undeclared files when a platform
renames a file (e.g. Batocera ROM1 vs gsplus ROM).
Bump database.json generated_at timestamp and add a new emulator metadata file emulators/ti99sim.yml. The new YAML registers the TI-99/Sim standalone emulator (ti99sim) with system info, core version, notes on ROM handling, and multiple required/optional ROM entries (with SHA1s, sizes and validation notes) for TI-99/4A support.
Add Atari 800 OS Rev B NTSC (CRC32 0e86d61d, canonical sysrom.c
match) and National FS-5500 disk controller ROM for openMSX.
Remove ROM_400/800_CUSTOM from retrodeck.yml (config slot key with
forward slash in name, not a real file).
Add many MAME/MESS BIOS entries (TRS-80 family, Bandai RX-78, Sega AI) and update docs/navigation counts (README, mkdocs). Remove empty supplemental file references from database.json and update generated timestamps and totals. Harden and refactor tooling: add MAX_RESPONSE_SIZE limited reader in base_scraper, make target scrapers an abstract base, narrow exception handling in the Batocera targets parser, and switch generate_pack.py and verify.py to use build_target_cores_cache (simplifies target config loading and error handling). verify.py also loads supplemental cross-reference names and accepts them through verify_platform. Update tests to import from updated modules (validation/truth). Misc: small bugfix for case-insensitive path conflict check.
Add Casio PV-2000 BIOS entry (pv2000.zip) to MAME and MESS profiles and update system lists/counts. Add Funtech Super A'Can BIOS entries (supracan.zip and umc6650.zip) with ROM contents to mamemess. Simplify and condense Vita3K emulator profile (rename fields, update profiled_date, add PSVUPDAT.PUP and optional PSP2UPDAT.PUP file entries, and clarify install/partition behavior). Bump database generated_at timestamp and add a system alias mapping "psvita" -> "sony-playstation-vita" in scripts/common.py.
Regenerate database.json and update README counts/timestamps; add and normalize numerous BIOS entries and hashes. Key changes: update generated_at timestamp and system count (355→357) in README; add OpenBIOS / HLE fallback and additional aliases to beetle_psx, include beetle_psx core name and profiled_date update; add laseractive to ares systems; adjust atari800 systems and source_ref line numbers; mark dinothawr as a system and expand its note; update gsplus upstream/profile date, add apple-iie system and tweak source_refs; add pcsx2 core to lrps2; refresh mame profiled_date and add multiple systems and BIOS root sets. Miscellaneous script changes and other JSON normalization to reflect newly discovered/merged BIOS files.
Add support for Coleco Adam, Entex Adventure Vision and APF M-1000 BIOS/ROM sets in MAME and MESS metadata (multiple Adam device MCU ROMs and optional FDC/SPI variants, Advision and APF BIOS entries). Update generated metadata across the repo: README coverage numbers and per-platform coverage rows, database generated timestamp and totals (total_files 7245), and various install manifests (notably batocera.json) with new timestamps, adjusted file counts/sizes, SHA1s, repo_path fixes and an added adam_fdc_320kb.zip entry. Also update notes to reflect the new system ROM sets in the emulators entries.
