noesis can open this file.

Put the .fpk extension on the files and extract with noesis

These files are compressed, maybe lz4.

jTexTool works with the samples you have uploaded, you just need to rename the file extension. jimg to .jtex.
You can also try Kukki, you can download it here.

Sorry, I think I expressed myself badly. I didn't want you to answer that question, I was just answering the question the Jamaicano asked.
English is not my native language.

Why would you do that when you solved it with hex2obj? :D Just answer the question he asked. btw, you should have mentioned TGFM to find start of face indices TGVU, TGFM: Really forgot to mention. iirc you were using py code for searching patterns in MUA files, didn't you? Yes, I would rely on that...

Maybe this helps: The faces were generated automatically, you must do some treatment with the faces, to see the UVs use WordUV.
There is also a script for noesis made by Allen that opens these files.

I believe it would be possible to edit the bms script to support UVs but I don't know how to do that and I would also have to ask the script's author for permission. It looks like there are some DXT3 textures at the beginning of the files. If you search for TGVU you will find the UVs and before the ...

Probably the script you are using doesn't support UVs, you will need another script to extract with the uvs
Post some example .ZIT files so we can analyze them

Files are concatenated, if you go to offset 0x5DD8 you will see a list of filenames contained in ND_R01.GRP.bin
I believe that for a better handling of these files it would be easier if they were not in a single file.

The script also works for Gundam Seed Battle Destiny PSVITA

So it looks like the sequence is UV, Vertices and then the normals. You may need to create a .bms script to extract the files, perhaps the file structure appears to be: long - number of files long - starting address long - unknown long - unknown long - name address long - unknown long - file size lo...

Rename texture files from .dat to .ktx
To see these textures, you can use ImageViewer.

You can see models with akderebur's RMA Viewer in this topic.
