[3DS] [Inazuma Eleven GO Galaxy] .xi / .xa

Heya, been a while since I was last here, but a friend reminded me to give ripping this game another try.

So far I've managed to seemingly get to the location of the sprites, but they seem to all be encoded as .xi and .xa files, some only as .xi, and I have no way of opening these files, nor have I found any record of anyone managing to.

Here are some of the Keshin/Avatar sprite files, or at least they seem to be judging from their location. 

The filesize of the player avatars from another folder seems a bit dodgy as well though, since I doubt 12kb could contain a full multicolor sprite. The files inside it when unpacked also seem like they wouldn't contain a full sprite, but I'm honestly not sure what's possible and what isn't right now.


If there's any questions, need for other/more files or anything, please do ask because I'm quite keen to figure this one out at last.
