Super Smash Bros. 4 Model Project

[Random Talking Bush]

A couple questions. I downloaded the animation files and i want to know how do i use the .mta and .omo files in 3ds max?
Also why are there two different sets of folders for the character models, (i.e c00, c01, ect, and l00, l01, ect).

The c00 ones are for costumes/recolors. Don't know what the |__ sets are yet.

The "l" sets are used for 8-Player Smash, they animate just like the 3DS models do with multiple hand bodygroups instead of finger bones and such (like the ones I showed off for Wii Fit Trainer in one of my older Twitter posts).
