It seems that someone at XentaX managed to find something out about this texture format. It seems to be used by many games: Star Fox Assault, Naruto Shippuden:Ultimate Ninja Storm 2, Eternal Sonata, Dragon Ball Z: Burst Limit.
The guy that was working on this format also says "But there was something else... *thinks* ah...., .nut files! I remember them from Tales of Symphonia (PS2 version)! They had TIM2 instead of NT*3"
From what I understand he explains that the textures he found in Tales of Symphonia for PS2 were NT*3 images (aka .nut), but with a different header. Maybe the TIM2 format that I implemented in Rainbow is a more generic texture container. Could you please send me some nut files? I would like to check if the structure of this nuts files is the same.
Maybe the raw pixel data is encoded in a console specific format, but the container should be the same.

I got some nut files from this game. It seems that the container is pretty similar. The main difference is that the images are tiled with a tile size of 8x8. I found two different encodings as for now: 4bpp and 8bpp with 16bit palettes. Here is how the first texture of the font .nut file should be (with an almost right palette):
