Notice the different subdirectories with names like abscam, and popeyeman. These are different variations of the game, which also have different ROM labeling (MAME's policy is to always match the labeling of the ROMs on the board)...

This is called the merged variation of a ROM.

== Split ROM set ==

Whereas, in the split form, one may have ROM ZIPs with each of the games, and their clones as seperate files, such as puckman.zip, abscam.zip, popeyeman.zip, npacmod.zip, and so on, each containing a flat set of ROMs for that specific game. This form is called a "split" ROM archive.

== How to solve Ingestion ==

The only clean way to solve inROMgestion here, is to literally have a relationship where one Rom entry in the game database may reference multiple individual Games. This way, we can catch on a file content hash and use appropriately.
