Practical use and curation For hobbyists using a MAME 0.139u1 ROMs archive, curation matters: matching the correct ROM naming and CRC checksums to the emulator version is essential for compatibility. Archivists should keep careful metadata (region, revision, board type, dump provenance) and store checksums to verify integrity. Splitting archives into prioritized subsets—by hardware platform, by region, or by rarity—helps both researchers and casual users access the most meaningful content without handling the entire collection.
