I wasn't particularly interested since I don't collect unlicensed carts anyway besides maybe the odd Tengen game. I did send him an email telling him to check ebay and see that all but one of his games had $5-$8 BINs and that $100 was way, way more than the value of what he had. No response of course and the ad remains. Wonk wonk.
