Mounting a bin/cue of the cd for this game works great, and once the game is launched the interplay logo plays find w/ sound but then it will error out claiming:
Zombie Error 04: Unable to initialize sound driver

However, randomly it will work.

I have attempted to define the 'set blaster' variable for the sbpro2 a/ matching drivers (lifted from the eye of the storm thread).

If I repeatedly launch the game enough times it will suddenly work.

Looking at the launch.bat file it calls DIGAUTO, which usually does not detect the soundblaster, which in turn causes the zd.exe file to return the error above.

Using the SVN build this error is fixed. I am posting this as an FYI for anyone who comes along later.
