idbeholdME: Actually. The game no longer works for me with those settings :D
The Windows update I did a couple months ago after several years of not updating must have broken it. Now I get just a black screen when launching with dgVoodoo.... :/
Used to have the same behavior as kalirion. Now, when I alt-tab, I can see the game for a split second before it goes black again. No idea how to fix that...
EDIT: Managed to make it playable. Downloaded the latest dgVoodoo and had to fiddle with the settings a bit. The game launches in a tiny window, but alt tabbing makes it the size set in dgVoodoo (1920x1440 for me). However, there are no black bars to the sides. But even before I did the Windows update, it behaved like that, I just had a black screen open in the background to simulate the black bars when I played through the game like a year ago.
Attached new dgVoodoo settings that made it work for me. Mainly, I had to disable application controlled fullscreen state.
managed to get it working, it behaves exactly as you mentioned, the only thing left is to make able to use the controller
