And the games can all appear in a single list?
Assuming so, does this have to be done on a game-by-game basis, or can I simply combine lists. So for example if I have 500 games in c:\MAME1\roms and 500 games in c:\MAME2\roms, I can just have it merge the two lists together rather than have to change the game-specific configurations for 500 games?
