• Scope: All available Cylum 39S ROM images in the repository under review (firmware revisions, bootloader, game/OS ROMs).
• Method: Compare SHA256 hashes of current images against known-baseline hashes; inspect binary diffs for signatures of modification (timestamped headers, added/removed sections, checksum changes); search patch notes, changelogs, and vendor advisories; sample runtime behavior in an emulator to confirm differences.

2. Translations and Fan Fixes One of the strongest selling points of the "Patched" label is the integration of fan translations. There are incredible RPGs on the Super Famicom (SNES) or PC Engine that never left Japan. Cylum’s sets often include these games with the English translation pre-applied.
