I am having trouble getting the God Mode to work. I am entering up-up-down-down-left-right-left-right-B-A . I would be very grateful for someone's assistance in helping me in this matter. Thank you for your time.

its probably a noob that is trying to waste your time and be mad at the game and destroy everything.
Dont get mad, theres probably no god mode!

up,up,dn,dn l,r,l,r, b,a is the way to get 100 lives in the old nintendo game called Contra. The person who told you to do that is pulling your leg.

Uh guys, I hate to bust ya, but I actually got it to work. You have to use it IN-GAME, not on the pause screen, or at the title screen, and you actually have to use the directional pad, just like the cheat post says, and you have to use it every time you start or restart a level. It does actually work, you just have to follow the instructions posted on the page.
