Converting .JTEX to PNG?

[otchi]

I used Kuriimu2 to extract 3DS JTEX to PNG files, but I'm getting mixed results.

Some works perfectly, some works alright but gives me images in messed up colours, and lastly some files (the sprites) gives me an "Format 5 is not supported by Encoding Definition" error. 

This is the sample sprite file that I'm having "not supported" issues with:

I have already tried Ploaj's tool, and it also gives me the sprite in messed up colours. Not sure if there's any other tools I can try.

If all Kuriimu2 does is just extract the image out without doing anything else, that sample doesn't seem to have an image inside.

It has an image for sure, since other tools does manage to spit out an image. It just comes out in weird colours, or the pixels are scrambled
