On my Marble Madness-when turned on the screen displays a message, "software exception error"...stays that way for about 1-2 minutes, then will go to attract and allow you to coin up. After that, it plays well for maybe 10 minutes or so then the screen goes weird and blue with a slight amount of static on it. Any ideas on where to start? I've had this game for close to 25 years and it is my keeper. TIA!
