.RTEX files - EXSTETRA Texture Files

[agathor35]

Okay so i'm getting back into the swing of things with translating games, and the issue im running into once again is these .rtex files.
I cannot figure out how to get inside them to view the textures correctly without the swizzle they have.
Since im translating these files all on my own i need to figure out how to do so with the ui textures and such.

that being said i need some major help with these files, kukkii cannot open them because of a lack of a plugin, and tileGGD has a hard time showing them but they have the swizzle.

Does anyone have any idea how to decode these files then re-encode them back with the translated files once im done?

Their not compressed their just in a format that is unknown, we got them to work in TiledGGD for a bit but then the other files wouldn't work at all and they have a bad swizzle.
