The Orion Nebula

I am running v1.31 on my PC fine via orion95, the mouse is twitchy but I can stand it. When I try and run the dos version 1.40 the colours and visual go all patchy. I have tried changing windows compatibility but it still wont work? my video card is a Raedon X1650 so the screen resolution can only go down to 800x600. Is this a problem?



Any help would be appreciated
