Mario Kart: Super Circuit question..

How in the hell do you erase the data? I want to start the game anew but I can't erase it. The manual says nothing and I can find no command to do it. Does anyone know how? On another note, does everyone know that you can unlock every singly track from Super Mario Kart. That's just badass. Help please.

uhh, forget it. I found it. Hold L,R,B,Start and turn the power on.

can't help you there. i imported the game when ir first came out in japan, so i can't read the options menu.
