Although the first thread says under question 10 (How do I get SMAC/X to run in a higher resolution/window?)"
"It isn't possible to run SMAC/X in anything other than a full screen.",
there is still a way to run SMAC in a window.
You can find it at the end of this article.
The only problem is that you cannot see the cursor.
Although there are some options to fiddle with, I didn't managed to get the cursor working right.
Any idea about this?
