Oh wait, are you talking about the LttP charging? Whoops, heh, I was thinking about the wrong game.
Hmm, I'm not sure if I've seen those ripped before. However, I know that Miles Lombardi ripped the actual spin attack for all four directions. He's now known as Ben on ZFGC, so contact him for the sprites. For some reason, I only have one direction (left) saved on my hard drive... wonder why I don't have all four.
