If compatibility options have not worked you, I am not sure how to help. My question is how do I get Alpha Centauri to work in Win7? Anyone, anyone, Bueller, Bueller....
Try a virtual OS. Maybe that'll worksies? A bit of a hassle, but if you're dying to play an old game (I know the feeling) and you don't feel like making a dual-boot then it may be worth a shot!
