BizHawk Macros for the Punch Hopping trick in Rayman: Hoodlums' Revenge for the GBA.
Hold J, K or L and your desired direction and press the frame advance key. Can work around all lag except on the first frame (wait one frame first in those cases).
  • J: Hop and punch next frame (gives speed and height)
  • K: Just punch (best for speed but loses height)
  • L: Hop, wait, and then punch (loses speed, but allows for sharp turning)
Even if you don't care about carefully optimising this game, it's a lot of fun to run this script, hold J and the frame advance key, and fly haphazardly around the level. Try it!
