If an arcade Rom (MAME, FBA, etc) has multiple sets (Set 1, Set 2) and each works, does it matter which to keep and which to delete? Is one "newer" than the other and thus less subject to a bug or glitch as the game plays on? I'd hate to delete 2 out of three and then the last boss glitches out or something.
