.TEX file editing, is it possible?

[Arlisbloxer05]

Hey there, so i've been wanting to do gamecube texture mods for a while, and although i have done it on Dolphin, i want to try it on an actual ISO.

So the game in question here is Final Fantasy Crystal Chronicles, but the problem is that the textures are in .tex files. I tried looking for a .tex editor but all i got were text editors.

Any help would be much appreciated.
