Someone recently gave me 7 n64 games. They were all stored together for about 10 years, and I'm guessing weren't stored all that well. I get no picture and sound for all them. I've taken each apart and throughly cleaned the contacts with qtips and alcohol. I've tried them on two n64s. If I try them on a gameshark, it gives he same error as when there is no cartridge. Has anyone had any similar experiences? Think I can get any of them working again?
