How to reverse controls FAQ
This is important.

To be able to play this game on GBA SP, GB Micro and Nintendo DS (Lite) you have to reverse controls (switch "up" with "down"). You can do it this way:

1. Choose the green option (icon) in the main menu.
2. Choose the blue option (icon) in the submenu.
3. Press (and do not release!) the following buttons: UP, LEFT, RIGHT, B.
4. A sound will play and a dialog box will be presented to show that you reversed controlls. Just press A.

To reverse the controls again, just do the same.

Have fun. :)
