Hi guys. I bought a Gameboy Mega Man 4 module on ebay considered as damaged. I tried the usual things like contact spray, blowing, slight rubbering... but the game refuses to start after the Start logo. As you can see on the pics the nintendo logo is damaged when starting the game. If you take a look at the contacts on the other pic you can see they are quiet used and abraded. There is something called "silver conductive varnish" on the market. Is anyone experienced in using this on a module? Or is there a chance to change the contacts? Or does anyone have another idea what to to?
