Hm, good things to consider. I'm using Nitsuja's Snes9x 1.43 +9, and so far no problems. I did make a wonderful find- Coo is in fact the fastest animal, because turbo A makes him fly extremely fast, like extremely, much faster than running, although it is hard to control. I think the turbo buttons in this game will have good affect, and selectively using Gooey occassionally with 2 player control. Now I have to set the controls of the second controller...
Coo/turbo tests
This is me fooling around with turbo in this game. Obviously it is done sloppily, I was doing it both with normal speed and FA, using only a mere 7 rerecords. I show examples, normal and then by using turbo/Frame Advance.
Floating is optimized with kirby with turbo A, and turbo A gives fastest Coo movement, which aesthetically looks faster than normal running. Can anyone verify if this is the fastest movement possible in the game? I also tested out Frame Advance sliding and running, turning corners and jumping quickly from run to slide and vice versa, as well as finding that when standing still, move in one direction for 4 frames, release that direction one frame, and hold the direction the next frame to go into running animation the fastest.
