I've a problem with GP2: sound doesn't work. I tried to read here "http://grandprix2.de/wissen/gp2_xp/gp2_xp2.html" but VDMSound doesn't work right with Windows Vista. The problem is that when I try to launch the shortcut named "SETUP" (the icon with a little black box with the text "C:\") a black empty window appears and I can't do anything. So I can't configurate sound.
I don't have much knowledge about this, but: Do you have DOS4gw.exe in your Gp2 folder? i believe this is needed to run the VDMsound programs, otherwise you can try DosBox instead of VDMSound, but i don't have experience with that...
Yes I tried with D-fend Reloaded program: when I launch the setup dosbox starts but doesn't work . I don't display the sound configuration page as is wrote in the manual....
