NES Nintendo World Championship gamings Holy Grail! NWC - eBay (item 250469343691 end time Aug-20-09 05:50:44 PDT) Good luck!
Very rare cartridge (though its the grey version which is not as rare as the gold one) Label seems in pretty bad shape though I dont have $4,000 to spend but if I spend that much I would buy a cartridge with a label in better condition
