I don't know if anyone can help me with this problem, but I tried to replace Whirlwind with Bulk Up, but moves no longer animate, and Bulk Up causes the game to reset in SGB mode. Restoring Whirlwind while leaving the effect in place makes the moves work as intended. I don't know if there is a piece of code that relies on Whirlwind that I'm unaware of.
Just because you can, doesn't mean you have to.
