I scored the Spongebob Plug N Play game for $.50 at my local Goodwill, but it doesn't quite work. When I turn the game on it starts changing colors from pink to green. Eventually it starts to distort sort of like a dirty NES cartridge. I took the thing apart, but don't know what to look for problem wise. If there is anyone that can help me out with info or a website I'd appreciate it, thanks
