Kotoyos Junk n Repair presents a: “B” Graded Nintendo 64 tested and working with 2 controllers and 4 games. Detected: controllers have the common problem of the sticks having heavy usage, they do however work perfectly fine. Other than that everything is in good condition. Both Mario kart and Super smash bros we been unable to test then since they require a Japanese N64 to play on them, but you can modify US consoles to make them able to play on it. We will clean the N64 before shipping! Thank you for stopping by! If you got any questions regarding to this item please dont hesitate asking!
