I haven't checked if they work. The games are Torneko's Great Adventure, SUPER R-TYPE, Doraemon: Nobita and the Kingdom of the Fairies, and Doraemon 4: Nobita and the Kingdom of the Moon, a total of four. I think Torneko's battery is dead. There is some discoloration, so please look at the photos. Torneko's box is crushed and folded. There is no instruction manual. *Please refrain from purchasing if you are sensitive to used items. Instant purchase is OK. Price reduction is not possible. Selling individual items is not possible. I will protect them from getting wet and ship them via Mercari delivery. Super Famicom SFC
