It works fine in XP mate, but it's basically the same as the first version - I don't notice any difference performance-wise.
As for emulators... don't talk to me about those, I've been having an absolute arse of a time this weekend trying to get DF running under one. Actually, truth be told, I'm just having trouble getting an emulator to run. Period.
But it shells out to DOS and you can Alt+Tab back into XP so no probs there.
