Superman buying for Nintendo NES

Product Name: Superman buying for Nintendo NES
This listing is for a vintage Nintendo NES game called SuperMan. This is an original owner game. It comes from a smoke free and cat friendly home. The game is NOT working. When I tried to test it a blue screen did come on but then froze. If you know how to take apart games and clean them you might be able to fix it. I've listed the item in poor condition because of this. The real value is in the original box and buying manual that are in great condition. The styrofoam insert and black cartridge case are included. If you have any questions please ask before purchasing. Item has been stored for the last 30 plus years.
