To build, audit, or repair a Full Non-Merged collection, you need two primary tools:
A DAT file is a text file (often XML format) that lists every ROM needed by the emulator, including filenames, CRC32 checksums, and file sizes. This file serves as the authoritative reference for what a correct ROMset looks like. Tools like ClrMamePro or RomVault use the DAT file as a blueprint to verify, rebuild, or fix a ROM collection. mame 2003plus reference link full nonmerged romsets

bios/ (Place any systemic arcade BIOS files here, though non-merged sets usually bake these directly into the game zips). roms/ (Contains individual, standalone game .zip files). roms/samples/ (Contains the audio sample .zip files).
Here is a comparison of the formats:
For , the recommended reference collection is a Full Non-Merged romset . This format is the most user-friendly because each .zip file contains every file required to run a specific game independently—including its parent ROMs and necessary BIOS files. Where to Find Reference Sets
