Title Screen Trick
On the Title Screen, press the B button for one time, then start rotating your analog joystick around until the number 64 on the end of the logo starts to move. Move it anywhere on the screen. You realise that the characters will follow it with their heads. Try letting go of the stick and it will return back to its initial position.
