I am using windows XP, and I tried the above website given.. I copied everything from the CD into my folder. It did not work - I am not sure why.. so I tried the old, try-and-test and see what happens. In the Compatibility of Orion95, I selected:
Run in 256 colors
Run in 640 x 480 screen resolution
Run in windows 95
It worked like a charm, it turns my screen black and white b4 it runs, but it runs with full color etc. I hope this helps anyone who might be stuck in a similar situation, Orion 2 is still my favorite game.
