Footnotes

  1. The programmers did an interesting way of programming how to subtract health from the character. Instead of a health bar going down as per normal when you get hit, the enemies are programmed to keep punching until the health does go down. Think about this for a moment. If your health doesn’t go down, that means you’re stuck. Turn this code off if this happens. That might fix it. Then turn back the code on. Or, to save all this hassle, just use the infinite lives code(s).
  2. TThe game doesn’t seem to like it when both players force the same character. Player 1 and player 2 can be the same character with a neat trick. If you switch the value of the person who chose a different character once the player selection screen is past, you should both begin as the same character!

    00 – Rash
    01 – Zitz
    02 – Pimple
    03 – Billy
    04 – Jimmy
