Pokémon Model Ripping Project

Okay so I want to extract some of the animations form these games but the BCH I downloaded form this thread only shows an untextured mesh in Ohana 3DS. Am I doing something wrong? Are there files missing? Do I need to download the whole game and unpack it? How do I do that?
Sorry to ask a question probably already answered but sifting for answers in a 80 page thread is kind of hard to do.
Any help would be appreciated.

Edit:
Also if I do have to download the game do I get X/Y or ORAS because I want some mega animations as well. I am just not sure if both extract perfectly.

Don't the Pokémon XYORAS animations have a different format or are they .bch?
