That sounds awesome man. I would love to avoid all of those weird adult card game Japanese titles, Mahjong, Etc. It's really just the non-working ROMs that are always such a bother. One other question though, what about the actual title of the game being selectable instead of the ROM name?
Thatwas always something that I hated about my setup. Like Killer Instinct is in the system is something like kijnt... something like that. It would be cool to select killer instinct from a list, and it plays...just like the NES, SNES, etc.... systems do.
