Punch-Out Wii .data files?

I loved the Wii version of Punch-Out since it came out, and I always loved how colorful the characters were, so I would love it even more if I could use those models in projects and such, but they're packed away in .data files, and I can't find any way to get into them. I've searched on google but every thread asking about said .data files died after anybody found it out. If anyone could help me figure out how to extract the data from the .data files, it would be much appreciated.

I have the files ripped from my personal copy of Punch-Out, but I can't seem to get at the models.

I don't have much skill in hacking files, but I'll certainly try to contribute what I know.
