-- GBA Rayman: Hoodlums' Revenge
--
-- Macros for the actions used while punch hopping.
-- 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)
