I bought an original wide-body Mario Bros from some years ago that went straight into storage. I finally pulled it out today. It powered on and plays. Pretty shocked that it just worked. I don't hear any sound. Well, I hear a little sound when I walk in the game, but it is very, very slow. I've read the manual and looked around inside. Is there a volume pot somewhere? I can't hear anything when doing the sound self tests. Where do I begin on this? I'd be thankful for any suggestions.
