to burn a 100% working copy of Gothic 2 you need a prog called Twinpeak 0.2(
http://kickme.to/blackcheck) and a BWA file(
http://kickme.to/copybase).
Just start Twinpeak, select the Clone CD Image from CD3 and select the BWA File. Push Start and after 10 Minutes youve got a cracked CCD Image which can be burned to a CDR...
thats it...Have phun
