Help with ripping from a game that has custom files

[Meowmere]

Alright, so I'm making a game based off of a failed one, which will never see the light of day, so far, from crawling all over google images, I have most animations I need, I just need attacking up, and attacking down, same with rolling up and down. So far I've only seen the attack down animation in a few videos, no dashing up or down however.
I do have an early build of the game, and it has external textures, sadly they are a custom .M2A file, is there anyone who know what to do with that?
