Can't get sprites from fighting game

[Macaulyn]

So, I was trying to rip sprites from this game called Trajes Fatais: Suits of Fate, a game on Steam that has been in development hell for a long ass time. I tried multiple asset ripping tools, but though I can get some sprites (some portraits, tutorial stuff, lifebars), I can't get the most interesting part: the characters and their specials. Is there anything I'm missing? Is there a way to hide sprites? How do I get them?

A bit of an update, I found something promising but I still need help with it: there folder called "Animations" in which there is a folder for each character, with those having around 300 files each, so those could be the key to getting the sprites, assuming each file isn't a sprite itself. Problem is, the files inside have a fake extension, .trafAnimation (TRAF used to be an acronym for the game) and I have no idea what is the original extension of these files were, is there any way to discover a file's original extension?
