looking for info on ciso compression

[pspZorba]

Does someone know what kind of compression it is?

is it zlib ?


is there a special header at the file start or is-it just the 4 bytes CISO ?

I have finally found info. I will share later when I understand everything.

OK I found the infos I was looking for.
To sum up,it's a Zlib compression, not a whole file compression, but a compression sector by sector, so as each compressed sector has a different size, those sizes are stored in the header of the file.
You can download the code here in English or here in French
