I recently bought a copy of Cratermaze cic, the seller said he wasn't able to get the card to work, so he sold it "as is." I figured it just needed to be cleaned a bit. I received the game, it doesn't look beat up, cleaned the contacts... and it doesn't work. It gives a "static" display, though I can hear what is supposed to be the title sound ("Cratermaze" drops down).
Is there any known cause or cure for this? Any ideas?
