The Jade Empire Save Game Format (.sac) is exceptionally simple:
Code:
32 bit (n) Number of GFF files in this .sac
-------------
begin GFF list
-------------
32 bit (x) Number of bytes the GFF filename including null
x*chars Filename including null termination
32 bit (y) Size of GFF
y*bytes GFF formatted file
(repeat n times)
The last GFF file in the GFF List is called save.sav and contains all the player related information. The other GFF files appear to be area/module information.
