So my Gray Original Nes plays all real gray cartridges fine, but when I try to load an unlicensed game from my collection like Firehawk and Master Chu and the Drunkard Hu, it keeps blinking and I have no way of loading the game.
Does anybody else experience the same problem loading unlicensed games? or do I need to upgrade to a Retro Duo nes/snes combo to eliminate these problems?
