I took the advice I was given earlier and burned some mp3s on a cdrw and it worked so I copied a sega saturn game that I already owned I used roxio and cdmate and when I played either disc all it did was play the music. What am I doing wrong? do I have to have a cart? Does the fact that I have the sega with the round buttons have anything to do with it? or am I just copying the game wrong please help
