I want to learn, but not sure where to start

[A.J. Nitro]

Well before I start getting some models from my game, I wanted to see if I could open up RTB's Petey Piranha model in BRRES and all I get is "Error: Not a valid BREES file" message. Also, where do I find the models from the game I want to do? I wanted to try SSBB.

EDIT: Never Mind, I was able to open Petey in Noesis, but with no textures. Also I'm still wondering where I find the models for SSBB.
