OK, for that I need to know the specs of the computer you're trying to run it with. But EMS? Back in the old DOS days, it was advised to play Jazz Jackrabbit after a "clean boot", meaning no memory drivers would be loaded during DOS start-up. It was a high-performance game at the time, so it needed all the memory it could get (can you imagine having only 2.5 or 4 MB of RAM on a 386 computer?)

I'll be waiting
