something else that may be helpfull: when I tried porting it to wineskin, I also get this error
Error RenderingSystem Init
and there are a couple topics about that on the SF rogue universe forum. apparently it has something to do with integrated graphics chips and how they are not supported. the newer macbook pro's (which I have) have 2 garphics cards. I wonder if the game is trying to start with the intel card, and failing.
