Professor Layton vs Phoenix Wright: Ace Attorney models

[Virt]

So I was hit up with some PLvAA model files. I managed to extract the files within those, but I don't know where to go from there.
Everything that was extracted is filetypes like .atr, .cmn, .mbn, .mtr, .prm, .sil, .txp, and .xi
(Oops, there are some others in other folders, too.)
Does anyone know about these or are they yet to be cracked?

Spoiler

Man, why can't any of these games have normal filetypes?
