Unpacked the .nltx files using this tool 

However it results in swizzling and the image is mashed. I'm pretty much a noob in this regard, though i have experience in normal coding, so if anyone can give me the method, tool or link a tutorial on how to fix it, it would be deeply appreciated. I found other swizzle discussions, however those use some terminology and numbers i am unfamiliar with. In an archive both the original nltx file and the raw dds file i got from it.

I have tried removing the commented line of code in the tool and got this. Shape is correct, but colors are all wrong.
 

nvm, found the issue, script was using wrong color format in dumptexture()
