NINTENDO64 Console + Accessories - Model: NINTENDO64 - Included: Gray Controller, AC Adapter, AV Cable - Game Cartridge: Mario 64 (Condition) I have confirmed the operation, but often only the red light comes on when the power is turned on. I was able to play by repeatedly inserting the cartridge all the way in and lifting it up slightly, so I believe the cause is a connection issue with the console's cartridge slot. Therefore, it will be difficult to play immediately after purchase, so I am selling it as a junk item. Please understand this before purchasing.
