pure python GF(2^233) field arithmetic, binary curve point operations,
and ECDSA-SHA256 on sect233r1. verifies OTP CTCert against nintendo
root CA public key. zero dependencies. sign+verify round-trip tested,
n*G=O verified, wrong key/message rejection confirmed.
pure python RSA-2048 PKCS1v15 SHA256 for SecureInfo_A,
LocalFriendCodeSeed_B, movable.sed. AES-128-CBC + SHA256 for otp.bin.
keys extracted from azahar default_keys.h, added RSA/ECC sections
to aes_keys.txt. sect233r1 ECC not reproducible (binary field curve).
adler32 hash via zlib.adler32(), min_size/max_size range checks,
signature/crypto tracked as non-reproducible (console-specific keys).
compute_hashes now returns adler32. 69 tests pass including 3 new
tests for adler32, size ranges, and crypto tracking.
trackball BIOS (236-bios.sp1, 236-bios_japan_hack.sp1) for irrmaze,
PCB BIOS (sp-4x.sp1, spj.sp1) for ms5pcb/svcpcb/kf2k3pcb. all carry
BRF_ESS flag in d_neogeo.cpp, verified against source.
Replace bios_zips section with structured files entries (category:
bios_zip, contents: with name/description/size/crc32) across all 4
MAME profiles. Profile mame2000 from source (was false alias of
mame2003_plus). Adds neogeo.zip, decocass.zip, hiscore.dat, cheat.dat.
add core_classification and upstream to all five profiles. kronos:
add ROM cartridge files (mpr-18811-mx.ic1, mpr-19367-mx.ic1), add
archive: field to STV blobs, remove unverified MD5 hashes, fix
cores list (remove yabause_libretro). jumpnbump: fix incorrect
note about embedded data. lowresnx, lutro, m2000: add missing
classification fields.
add --emulator, --system, --standalone, --list-emulators, --list-systems
to verify.py and generate_pack.py. packs are RTU with data directories,
regional BIOS variants, and archive support.
validation: field per file (size, crc32, md5, sha1) with conflict
detection. by_path_suffix index in database.json for regional variant
resolution via dest_hint. restructure GameCube IPL to regional subdirs.
66 E2E tests, full pipeline verified.
Move 17 case-colliding BIOS variants to .variants/ so Windows
and macOS clones no longer lose files. Existence-based platforms
keep the primary, MD5-based platforms resolve from .variants/.
Also fix resolve_local_file zipped_file resolution: when multiple
ZIPs share a name, verify the inner ROM exists before accepting
a candidate. Fixes adam_fdc.zip resolving to the wrong archive.
Batocera upstream has a truncated 29-char MD5 for zx48.rom.
The scraper now resolves truncated hashes via prefix match
against database.json, preventing schema validation failures.
resolve_platform_cores() links platforms to their cores via
three strategies: all_libretro, explicit list, system ID
fallback. Pack generation always includes core requirements
beyond platform baseline. Case-insensitive dedup prevents
conflicts on Windows/macOS. Data dir strip_components fixes
doubled paths for Dolphin and PPSSPP caches.
- fix KeyError in compute_coverage (generate_readme, generate_site)
- fix comma-separated MD5 handling in generate_pack check_inside_zip
- fix _verify_file_hash to handle multi-MD5 for large files
- fix external downloads not tracked in seen_destinations/file_status
- fix tar path traversal in _is_safe_tar_member (refresh_data_dirs)
- fix predictable tmp path in download.py
- fix _sanitize_path to filter "." components
- remove blanket data_dir suppression in find_undeclared_files
- remove blanket data_dir suppression in cross_reference
- add status_counts to verify_platform return value
- add md5_composite cache for repeated ZIP hashing
Added exclusion_note field to emulator profiles. verify.py reads
this field instead of parsing notes text with fragile keywords.
desmume2015: explains .info vs code discrepancy
dolphin_launcher: explains standalone BIOS management
All exclusion messages now come from YAML data, not Python strings.
New section "Intentional exclusions" explains why certain emulator
files are NOT in the pack:
- [frozen_snapshot]: code doesn't load .info firmware (desmume2015)
- [launcher]: BIOS managed by standalone emulator (dolphin_launcher)
- [standalone_only]: files for standalone mode, not libretro
Makes it clear that omissions are by design, not bugs.
Created desmume2015.yml with files: [] (code doesn't load BIOS).
Removed desmume2015 from desmume.yml cores list.
Removed cdi2015 from same_cdi.yml (separate profile exists).
Frozen snapshots must have their own profiles because their
firmware behavior differs from the current version.
_collect_emulator_extras() now uses find_undeclared_files() from
verify.py instead of manual emulator name lists. This gives:
- System-overlap matching (automatic, no manual config needed)
- mode: standalone filtering (no standalone files in libretro packs)
- type: launcher filtering (no launcher BIOS in system_dir)
- data_directories coverage (no false gaps)
- hle_fallback propagation
- Works for ANY platform (same logic for RetroArch, Batocera, etc.)
RetroArch --include-extras now discovers 91 extra files from
emulator profiles automatically.
Added hle_fallback: true/false per file in emulator profiles.
When a core has HLE and the file is missing, severity downgrades
to INFO instead of CRITICAL — core works without it.
verify.py builds an HLE index from emulator profiles and applies
it during severity computation. Cross-reference now skips launcher
profiles (type: launcher) and includes hle_fallback in undeclared
file reports.
33 E2E tests (4 new: HLE severity, HLE index, launcher skip,
cross-ref HLE). 0 regressions.
Based on source code analysis:
- RetroArch core_info.c:2233 — existence check only, no blocking
- PCSX ReARMed psxbios.c:28 — full HLE BIOS replacement
- Dolphin CommonPaths.h — all files optional with HLE
- snes9x — DSP HLE built-in, coprocessor files optional
Removed 7 test files (135 tests) fully covered by test_e2e.py.
The E2E creates all fixtures in setUp, exercises every code path
with real files and real functions. Single source of regression.
