     Press  any button at the title screen. Leave the game at the main
menu  for a few minutes until it returns to the introduction sequence.

of Peter Brackly.

Easy money:
     When you are doing a cup, remove your memory card and do the cup.

the  shop  and  buy  anything. When you have selected what you want to
buy,  insert your memory card again and save what you have bought. The
cup  that  you won will not be saved. Restart the game and the cup you
have just won will be gone, but the item that you bought will still be
there. Do the cup again and to get a lot of money again.
