I have been exposed to this format 8 years ago, when I was working on a game translation and localization project. At the time, I was very confused about the compression algorithm. Finally, my friend helped me to disassemble the main program and use the assembly code of the game to decompress the data. I have never figured out what the compression algorithm is.
Today I saw this format and I remembered it. I searched for related information and found that someone had figured it out. It turned out to be LZ4 compression.

Thanks to personperson for the compressed format information.

So I wrote a script to help you import and export. Hope it helps you.
My current method is to decompress the data, modify it and import it back, and remove the compression flag.
I did that in my project at the time and it worked.

**Edited""
Added DXT5 Support.

Updated, they are in DXT5 format.
I still remember that there should be other formats, but many years have passed and I don’t have more samples.
It can work for the current game.
