Hello, does anyone have a script to decompress a file specific to High Impact Games studio?

It contains textures, sounds, and other things.

GLOBAL.zip

Seems like someone has already made a partially working decompressor: https://github.com/electrogecko/UYA_pyTools/blob/main/SM/tjzip_dump.py

It doesn't work for the files in ETC tho and it's also just decompressing, not extracting individual files

Added support for the format in my extractor WITH individual file and not just a decompressed blob as output: https://github.com/smiRaphi/UniPyX

It relies on the script above for decompression tho so the ETC files still won't work

I extracted the file from memory and it seems to be decompressed, but why is the HIG header still there?
File from 0x167000 to 0x6B994B

RAM_Dump.rar

Yeah I'm aware that the decompression is not fully working but I already made an issue on the page of the decompressor and hope that I'll get a response but I'll also see if I can take a closer look maybe in a couple of days

haha, I just used the tjzip_dump.py which NeoGT404 pointed to, had to change the header size of the wad to 0xC0, got an out.bin with contents like this

edit: upps, what happened?

i did not see the tjzip.py, i found the logic debugging in ghidra

In the game's code, the loader reads a 0xC0-byte header and passes the pointer plus the 0xC0 offset to the decompression function. This shows up in as: FUN_0000ff60

It also verifies that it is version 6 before decompressing.

Its a lz reflections

Thanks! (need to use your Ratched_Wad tool on my other PC with newer .NET version)...
