Apparently either Star Wars Galactic Battlegrounds, nor Clone campaigs will play CD Audio if you have more than one CD-drive.
I checked main site here for a patch, and found a "Fix music" for Battlegrounds 1.1
However, I've got Clone Campaign (cracked...) 1.0 and the *.bin - disk mounted by Daemon Tools.
The Windows CD-player have no problems playing the music on the disk.
And yes. I know the game is a bit old now... but it's so fun.
So anyone out there who could help me?
