Acceleration Glitch
Note that this glitch requires the use of a NES controller that allows Left and Right on the D-Pad to be pressed at the same time. If you hold Right on the D-Pad, then press Left, you will move to the right with much higher speed than is normally possible. About one second after moving extremely fast, release Left on the D-Pad and you'll continue to move at that speed until blocked. (Note: This glitch will not allow you to go super-fast to the left, just to the right.)
Maxed Passwords
These passwords are so named because they give you the maximum number of lives, olives, skins, and all items. All bosses are also classified as having been defeated, and the Attica Child is rescued.
