A "Reference" set means the ROMset matches a specific, known-good dat file (XML used by ROM managers). The official MAME 2003-Plus GitHub page provides a .dat file. A "Reference" set is one that validates 100% against that official dat. No modded ROMs, no bad dumps.

The downside to Non-Merged sets is file size. Because data is duplicated (shared assets are copied into the Parent ZIP and the Clone ZIP), the total size of the ROMset is significantly larger than a Split or Merged set. For MAME 2003-Plus, a Full Non-Merged set can be substantially heavier on storage than its Split counterpart.
