Recently, I purchased a Famicom console online. It had arrived in the mail today and, using my Sega Genesis power adapter and my SNES rf adapter, I hooked the system up. However, no matter how much I tilt the cartridge, or clean it, the system just doesn't want to play it. All I'm getting is a grey screen and the occasional dark brownish screen. I'm starting to suspect the Famicom itself is at fault, more than likely in the 60-pin connector. If this is the case, can anyone recommend me a technique for cleaning the pin connector? I would be grateful in return.
