Hi. I got a Sega Saturn on ebay not too long ago as untested. It powers on but keeps freezing intermittently. I got Rayman for it today and left it paused for a bit on 2 occasions ant it just froze while paused. I noticed skipping between track one and the last track on a CD repeatedly makes it freeze up very often. What's most likely the issue? I have a multimeter if I need to test points etc. Thanks.
