So very stubbly.
This page is rather stubbly and could use some expansion.
Are you a bad enough dude to rescue this article?
To do:
  • Regional differences (trivial things like the font palette)


There are two known cheat codes in the game, and the first must be activated before the second one will have any effect. Despite a lack of official documentation, both cheat codes have been tested to work.

On the Data East screen, Down + C + Start must be held on controller two.
With this cheat code, pressing Start on the second controller will skip to the next level. This applies to all levels except for the final one, where nothing will happen (the game will not skip to the ending). If the game is paused when this is done, this cheat will take effect when the game is unpaused.
After the above cheat is active, the Options screen must be opened and sound code 21 must be selected. Up + A + C should be held on the second controller and the Options screen should be exited by pressing Start on the first controller.
If performed correctly, holding any button (or any combination of buttons) on the second controller while the game is paused will cause the player to become invincible. Pausing and unpausing while no buttons are pressed on the second controller will deactivate this feature.
