Debug menu
In order to activate a debug menu, press and hold, and then reset the system. Keep these four buttons held down, and wait for the title screen to show the option to start a new game. With these four buttons still held, tap 8 times. If successful, a new screen will appear with a number of different options.

In all options, press to increase the selection, and  to decrease the selection. Press to begin the game with the selected options.
 * すてーじ NO (stage number):Choose which stage you wish to start the game in, from 1 to 7. Press  to alter between starting in しんぼる (Overworld) or ばとる (Underworld).
 * けん NO (sword number): Chose which sword you possess when starting the game, from 0 to 5. This actually allows you to possess a sword in early stages that you could not otherwise possess until purchased in a later stage.
 * ライフ (life): Increase or decrease the number of hearts in your health meter. The default is 3, the maximum is 8 and the minimum is 1, meaning you can set the game to begin with fewer hearts than ordinarily possible.
 * ヘン玉 (Bolt Bomb): Decide whether to begin the game with no Bolt Bombs, or the maximum of 99.
 * MONEY: Decide whether to begin the game with no Coins, or the maximum of 9999.
 * SOUND: Select a number and press to hear the music associated with that number.
 * EFFECT: Select a number and press to hear the music associated with that sound effect.
