It's ASM, but that knowledge alone wouldn't be enough to reverse-engineer it. I'd imagine that the code for that particular sprite-change is buried deep in the game engine. It'd be hard to find, let alone reverse-engineer -- unless someone already has, that is.

JPAN's FireRed Hacked Engine adds functionality that allows you to change the player's overworld sprites from a script. His patch is meant to be applied only to a clean FR ROM (it deletes a lot of stuff), but he also has a hack tool that can apply the changes to a hack-in-progress (it's trickier, though).
