If someone wants to pick this up, here's some info I have from extracting .nltx for a different game 1.5 years ago.
(viewtopic.php?f=7&t=8503 is that topic, but the old nltx.bms doesn't work here.)
Can't be bothered to research any further into this again, lol.

• .nltx files contain single textures.
• texture width is a 4-byte little endian number at offset 0x18
• texture height is a 4-byte little endian number at offset 0x1C
• texture data is contained in a YKCMP archive at offset 0x80
  
  • bms now has support for ykcmp extraction
  • alternatively, https://github.com/iltrof/ykcmp can also extract
    that data with:
    Code:

    ykcmp.exe -a 0x80 nltx-file [output-file]

• the result is raw pixel data, in one of the DXT formats, I assume
  
  • in the topic 1.5 years ago the .nltx files had raw RGBA data,
    but it's definitely different here
• the pixel data is swizzled
  
  • no clue about the algorithm, OP should at least say which game this is from

The game is Labyrinth of Refrain: Coven of Dusk from NS verstion.
