Here's the thing:
Last year I got this game to work using the solution in the other thread. But i decided to play it again and when I want to start the game it wont budge. Just the maddening black box and then, nothing.
Here are my settings for the cycles in the Dossbox.conf file.
core=auto
cycles=20000
cycleup=500
cycledown=20
Thanks in advance for your suggestions.

Never mind.
Apparantly you can't have itunes running in the background since the game won't start up properly.
Sorry for the redundant topic :(
