There are five variants of scripts on the QuickBMS homepage for unpacking these archives (ABGO, NFS2010Wii, F1, ABStarWars and DLS20), they all work perfectly both for reimporting and extracting but I wanted to make it easier to support all versions of the format with only one script. Upon getting better experience for both generally studying formats and writing QuickBMS scripts, I wrote my own version of an XGSPAK script using code from the existing scripts as well with my own to detect the versions. I'm pretty sure reimporting works too but I haven't tested.

Please do not reply unless when reporting bugs. I will not plan to automatically detect version 0 First Touch paks with a modified header of version 1.
