Thanks again Maki!

I tried it and you guess: Epic fail (or almost)...
At least I could decompress the dat's, that worked. The files in the folder can't be decompressed though. It says "Not LZ77 compressed file; Header is wrong!"

If I use -unzl77 on a random *.lz file decompress it as the filename I give it but how do I know it's a texture? Going over aprox 5.100 could take loooong. *_*

Which file you tried to export? If it's not LZ77 file, then it gets unpacked as is.

About unlz77, we don't know it. We have to reverse the game and find corresponding file. Looks like FFIV uses format like Model+texture- it's impediment. I think easier would be just to hook DirectX renderer and change textures from there.
 
The lz files that are extracted from the dat like in streaming.
The game operates in OpenGL sadly. :/ I could manage to hook it via umod but it's not running that well and has some graphic error. :/
 
So right now I can't do anything with your unpacker/repacker or did I miss anything?
What is it good as of now and isn't there really a possibility to unpack the texture files? :(
 
Any news on this?
I really want to enhance the subpar texture quality of it. ^^
