I'm currently running Colonization on a P4 (3.0GhZ) with 1GB RAM and Windows XP HE. I'm using DosBOX 0.61.
The game starts fine and also runs without any problems, however when I want to play music taken from the "Military" or "Independence" folder, the game just produces extreme screeching noises. It DOES sound familiar to the actual music file, but it's still just loud screeching. The same goes for fighting sounds (i.e. when my Dragoon attacks some poor indian village).
I already tried to work without DosBOX and used VDM Sound, the problems however remain the same. I don't know what I'm doing wrong, or if it's a game-related error.
