So far the games seems to work on Vampire 1200, even though @AgedCode said that one betatester reported issues specifically regarding Vampire 1200. It would be nice if the person in question could reply do this thread and name the issues, so I can check on them.
Installation was kinda tricky, as the installer just didn't want to work when started from my fully configured RTG OS3.2.1 system. It ended in a black screen. I had to install a base OS 3.2.1 running in native PAL mode with only network to get the installer to work.
So far this is all I can say. I will look into it again, when I'm back from my trip to Berlin and Oldenburg.
Thanks again to AgedCode and marmacc for their great support and kind welcoming at their stand on Amiga37. Kudos also go to aPEX who pushed me (softly) to buy a copy
Hopefully when the winter days are getting closer I will spend even more time playing it!
