Extracting Arcania .pak files
While messing around with the Arcania demo, I noticed most of the pak files start with a signature of "SBPAK V 1.0". A quick search pointed me to a QuickBMS script for a completely different game, but the signature is the same. With slight changes the script is able to extract the Arcania paks too, at least partially. Posting my modified version here in case anyone else might find it useful.
