* Escape Trick : There is an escape mode that allows you to go through the stones and any moving walls. To activate it, press the A and B buttons at the same time while moving. There is a cost involved, though - it deducts 20 seconds for each stone or wall passed through.
* Boulder Dash Part 2 : There is a way to access Boulder Dash Part 2 from the attract mode (Part 2 has the same levels, but increased difficulty). To access it, press the following key sequence while the player list is onscreen : A+Up, A+Down, Left, Right.
