I recently purchased and installed the Space Rangers 2: Complete version from Impulse, which contains the original game and the Reboot expansion. After a little tinkering with it in Crossover Games, I have determined that the game will actually run just fine, but the graphics are unable to draw to the screen. If you drag a Mac window across the Crossover window, it draws the frames behind it as the Mac window passes. The same happens if you open a Mac menu over the Crossover Window, or drag the Crossover window off of the edge of the screen and back. But, if left alone, the graphics do not refresh, despite the fact that the game is actually running happily behind the static screen.
I'll keep messing with it and see what I can do.
Incidentally, all I did to install it was purchase and download it from Impulse while booted into Windows, then drag the whole install folder from my Windows partition into a Crossover Games bottle. Since Impulse won't run without .Net, I know of no other way to get it done.
