EmuCoreX Cheat Catalog

Community-maintained PNACH catalog consumed by the EmuCoreX cheat manager.

The repository stores catalog metadata and validation tools. PNACH files are mirrored when redistribution permits it; otherwise the catalog uses immutable upstream commit URLs. Every entry preserves authorship and its original source URL while branch changes cannot alter the reviewed file.

Files

• cheats.json - production catalog used by EmuCoreX.
• sources.json - approved upstream collections and their attribution.
• schemas/cheat-catalog.schema.json - public format contract.
• files - PNACH mirrors grouped by credited upstream source.
• scripts/import_pcsx2_collection.py - reproducible multi-source catalog importer.
• scripts/build_pcsx2_curated_batch.py - strict audited batch builder for pinned PCSX2 patches.
• scripts/validate_catalog.py - dependency-free catalog validator.
• scripts/validate_audits.py - verifies pinned non-mirrored batches and content-hash deduplication.
• scripts/verify_audit_live.py - downloads and strictly checks every external file in an audit.
• audits - immutable source, size and SHA-256 records for curated batches.
• frame-generation/support-v1.json - revocable compatibility manifest for the optional EmuCoreX LSFG integration. It contains no proprietary shaders or DLLs; users must import their own legally obtained Lossless.dll from Lossless Scaling.
• LICENSES - license texts for redistributed or generated source-derived packs.

Updating the upstream catalog

python scripts/import_pcsx2_collection.py
python scripts/validate_catalog.py
python scripts/validate_audits.py

The importer pins remote raw files to the exact upstream commit used to build the catalog, keeps credited alternative collections for the same serial/CRC, and validates that every selected file contains supported PNACH blocks. The GPL-3.0 CheatDevice conversion is regenerated from an immutable source database, then checked against audited output hashes and pinned serial/CRC evidence. The official PCSX2 patch batch keeps direct immutable upstream URLs, accepts only new CRCs with strict PNACH syntax, and maps titles from a pinned GameIndex. The current catalog exposes 9,594 verified entries from sixty-two credited sources; the app merges additional packs instead of overwriting cheats already installed for a game.
