I'm sorry if this is in the wrong section. When I play Metal Slug on my US Saturn the games kinda lags. It gets really choppy when there is alot of action on the screen at once. It is almost unbearable at times. Now my question is, what is the cause of this choppiness and is there a solution? I was thinking my Saturn might need a cleaning. Or maybe it is because I am using a 4-in-1 cart on a US system and I can avoid it by playing on a Japanese system with that official cart that came with the game itself. Can this be fixed or do I just have to deal with it like everyone else. All help and expertise is greatly appreciated.
