Hmmm, how about removal of idiot messages about cocktail modes in DRIVING games and other games that never had a cocktail mode in the first place (cough, Sega Turbo, cough).
Do the dip switches work in Star Wars or Empire yet?
I would also support the removal of all bootleg games, If Mame isn't about piracy then WHY are the bootleg games supported? There is no way to own a legal copy of a bootleg game.
I would also like to see Pac-Man as the parent and Puckman as the clone. It is not relevant that Puckman came first, in all other games the final revision of the game is considered the parent and the earlier revisions are clones.
Not in Mame's current scope, but I would really like to see NES, SNES, Genesis, and Master System support in MAME itself. It is capable of it (emulates offshoots of all those platforms perfectly). Mess is a freaking MESS, I want this stuff in MAME, no other emulator is as good and useable as mame, I see no reason why console functionality can't be added.
