Did you try to mount the game.gog image using imgmount?
Should look something like:
imgmount d "game.gog" -t iso -fs iso

Note: game.gog is not in the primary darkland folder - it's above it one level. Move it into the darkland folder to make things easier.

Here is what I did to make this game work decently on Dosbox Turbo.

1. Perform the sound fix in this thread. http://www.gog.com/forum/darklands/problems_with_sound

2. Set cycles to 15000.

3. Set the sound device to Sound Blaster Pro 2.0

4. Turn off Turbo Audio.

The intro screen should now move smoothly and eventually it will register your click or esc key to take you to the menu. The music and audio may still sound a little screwy and annoying but the game seems to work just fine.

Hopefully someone sees this, knowing this is an old thread.
Anyway so i managed to get the game running smoothly, BUT the game locks up and freezes when entering combat.. :(
Anyone have any ideas of causes?
