Anyone having trouble with A FInal Unity on XP should follow these
instructions. DosBox didn't work for me, but this was a doddle. After a decade, I can finally remember how good this game is!
I recently got A Final Unity, and I just wanted to say that this method works perfectly for me. The game runs perfectly, with the sole exception of the random game crash. Still, that's pretty good considering it's a pre-Windows game running on an XP machine.
