Cool, I'm learning things! 
The first time I try I'll probably go for a Wii game (not sure when that'll be though). Thanks everyone I'm now actually feeling encouraged to try working with models! I had originally assumed that models were all about complex numbers and doing a bunch of long and winding maneuvers, and just kind of thought it'd be too complicated for me.
EDIT: I plan to try Bomberman Land Wii when I get to it. So I guess I would just extract the model with Dolphin? After that, what would I do, open it in a model program and fix it up (not that I know anything about that) then submit it?
