How do you rip models from Mario Power Tennis/Toadstool Tour

I don't know how I am supposed to rip them, the Wii version has .sbn files and the GameCube version has no file extensions and the names are just the letters of the alphabet. I tried using NinjaRipper with Dolphin but the models get distorted.

From what I can see, in the GameCube titles, the game files are ALL supposed to have file extensions, because in Toadstool Tour I located THP's in the exact folder A/T files C, D, E, F, G, H, I, L, and N seem to actually be THPs and can be played lile regular THPs. This is likely a technique used to make modders not look through the file system due to confusion, because they could not locate anything, but with the help of a HEX editor, I was able to locate these files.
