Hi. It seems to be a container for images from Switch games. I've put together some info on the wiki
https://rewiki.miraheze.org/wiki/Hayarigami_NLTX

 

You can use this tool to decompress https://github.com/iltrof/ykcmp

like this:
 

ykcmp.exe -a 0x80 file.nltx file.nltx_decompressed

and then you can inspect image data in ImageHeat https://github.com/bartlomiejduda/ImageHeat

 

Sample I was investigating "ci1120.nltx" was a 1920x1080 BC7 image with (custom?) Nintendo Switch swizzling applied.
Haven't figured out swizzle method yet... But closest one is (4,8)

Ah thank you for the answer! Hopefully the way for it to be deswizzled can be found out!

I did this one with ci0010.nltx

It seems like you have to process it in parts - if you do it as 1 image, the unswizzling doesn't work, but if you unswizzle it separate blocks of height=256 it seems to work, at least for this one, which is 2 separate parts of height 256.

I just did it manually in Noesis, it *might* be possible to script it if all of the images follow the same pattern.

I just used these 2 commands (twice), and joined the 2 decoded parts together to make the complete image.  I haven't tested on other files, so I don't know if they all follow the same pattern.

    image = rapi.callExtensionMethod("untile_blocklineargob", raw_image, widthinblocks, heightinblocks, 16, 8 )
    image = rapi.imageDecodeDXT(image, width, height, noesis.FOURCC_BC7)
