I tried to play several games on my 3660, but the only one I played ( and with the normal version of MAMECE3) is scramble... I've downloaded the MEGA version of the program, but the only difference seems to be the longer list of ALL games supported... Some games, like Ms Pac-man, are found by the program, but don't work ( the screen turns blue for a few seconds, then go back to the list). The other games (I tried sf1, puzzle bobble, nba jam) are not found by the program, even if they are supported by this version of MAME- they are in ALL GAMES list- and the right file is in roms directory. Please help me, I'm really hopeless ( just like my english ).
