Heya, unfortunately avoiding DOSBox would require me doing a native port to Windows. Based on a test port I did with an older version of the game's engine, it didn't run all too well, even on a modern system; I'm really not sure why. Trying to port it again is low on my list of priorities.
That being said, there *are* two options for running the game under XP: either manually setting up the DOS version in an older version of DOSBox (not the "Staging" version used for WH), or if you don't care about music/sound, the DOS version can be run directly via XP's built-in DOS VM. Hope that helps!
