(re: Space Quest 4 CD)
I remember this issue coming up on the adventuregamers forum. Unfortunately, I don’t remember the solution. Adventuregamers has been down all summer so I can’t check the archives for you. But you could try posting your question at their temporary forum… maybe someone who posted to the original thread will read it and have some advice.
