34 Lives Code
After starting a new game in arcade mode on the normal or hard difficulty setting, wait for the first level to start and then tap up, up, down, down, left, right, left, right on the touch screen. Then press B, A, and then tap the center of the touch screen. "Up" on the touch screen refers to the top of the screen, "down" refers to the bottom of the screen, and left and right refer to the left and right sides of the screen. This must be input before the chopper drops your character on the ground, so it must be done very quickly. If done correctly, you will start the game with 34 lives.
|On the touch screen, tap: up, up, down, down, left, right, left, right. Then press B, A. Then tap the center of the touch screen.||34 lives|

Upgrade Weapons Fully
Enter the Konami Code (Up, Up, Down, Down, Left, Right Left, Right, B, A, Start) in the pause menu to either upgrade your weapons fully when entered for the first time in the level or kill your character. It can only be used in Normal or Hard mode (Easy gives you full upgrades automatically).

99 lives glitch
This glitch will allow you to obtain 99 lives. In order for this to work, you must have zero lives left, and die at the same time you get an extra life. The best way to do this is by killing the mini boss of level 1 because that usually gets you an extra life. Get hit by one of the fireballs it drops down on you the instant you destroy it.
