Multi-step jump
Jump towards the wall or edge of the screen and press the A button to jump again. However, the timing is extremely strict and it is not practical. It is also possible to jump an infinite number of times. If you can use it to a certain extent, you can make a lot of shortcuts depending on the aspect.

Data initialization
If you press [Left + Select + Start + B] simultaneously on the save data loading screen, the All Save Data Clear window will appear. Although it is a hidden command, it is written in the manual and it is normally possible to delete saved data individually, so it has little purpose.
