Replacing Link's boomerang with an imported model

[Soma]

okay, so I'm fairly new to actually hacking, but I was wanting to know how it would be possible to put a imported model over say, links boomerang, I know how to replace the mdl0, textures, and chr0, but when I try to use it in game it crashes, the model/animation of what I want to replace it with is here http://www.mediafire.com/?tp5iiy9fnen5lj9 , I'm thinking it has something to do with the bones, but I'm not sure....but any help would be greatly appreciated.

Rename the bones to the same as the boomerang, the only thing I can think of.

no, I didn't think that would have anything to do with it since I've already replaced the boomerang with Toon Link's before, and I already tried that but it didn't work ._.
