I used DOSBOX. Perhaps I did not have a good configuration, but on ALL the games I have tried the mouse/cursor either does not exist or doing a left click causes it to jump some distance. This makes it difficult to play mouse-dominant games, which I expect to include Darklands and Betrayal at Krondor. Might and Magic: World of Xeen is fine as everything can be accomplished with the keyboard alone.This is one I'd be interested in as well. A shame to learn it has mouse & sound trouble. How did you try to run it? Dosbox?
As for the sound, in both Darklands and Betrayal at Krondor there was silence when I expected there to be music. Since I have not played them before, I am not sure what to expect. So, for the moment, I wait until the Pyra.
