This patch will reverse the constant cutting of Kirby's momentum.
This technically affects all of the animal friends, Gooey, and Kirby. This change in physics will vary due to character mechanics (e.g. the way Pitch works, his momentum will always reset due to having a set air speed).
The ROM can decompress using exhal.
