I have a sega saturn, and my cartridge input stoppd working all of a sudden. I bought the system used and I bought a gameshark which is the only cartridge device i have used for it, and then one day my saturn stopped going to the gamesharkscreen and when i put the gameshark in sometimes it will go to the system screen when you have nothing in the cd tray, and if i go to load application it starts going all slow. My question is if my gameshark is shot or is it my cartridge input. I wish i could go out and buy another gameshark and test that but down here they are hard to come by, any suggestions? Thanks!
