I agree with George on the NES Contra part, but I'm pretty sure it got you 30 lives. There may have been other games that used the code, but they all stood in the shadow of Contra's giant, swinging, earth dragging weiner. One of the best NES games ever. If you say any of the other games that may have used that code and not Contra I'm starting a ban poll on you. :)

Is this response too early? I remember there being a start time in the rules but I am too deep into typing this out and too lazy to go back and look.
