I would like to have these extracted please.

Dat.zip

Looks like it is just a continuous stream of zlib chunks. Try the attached Python script. It will prompt you to select the archive files, then choose a folder to extract them to. Note that I am assuming the header always has the same fixed length and three-character signature at the start.

csi_ny_zlib.py

Added support for it in my extractor with the ability to read the file table: https://github.com/smiRaphi/UniPyX (https://github.com/smiRaphi/UniPyX/commit/54e45a39b775e7269367a1e0c18eb4632b7d585b)

I get this: UniPyX
[]
Traceback (most recent call last):
  File "C:\Users\jaker\Downloads\UniPyX-main\unipyx.py", line 53, in <module>
    extract(inp,out,quiet=False,rs=True)
    ~~~~~~~^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "C:\Users\jaker\Downloads\UniPyX-main\lib\main.py", line 861, in main_extract
    if rs: assert ts,'Unknown file type'
                  ^^
AssertionError: Unknown file type

Oop, seems like I was looking at a different version, should be fixed now. (https://github.com/smiRaphi/UniPyX/commit/b2884aeac7cc9caef6532995ab2fdd9e28bb8793)

Hi, could you explain how to use this tool?

It's in the readme of the repository, just install python (I recommend 3.14 as that's what I use/test with) and then run "python.exe unipyx.py <your file>" in CMD.

Great, it works perfectly, but how do I repack the files?

It can't currently do that as it's focused on extracting things but I'm more than fine with anyone looking at how I extracted it and then making a repacker off of that
