Dune 2000 Tutorial - Activating Maps Manually, using the String Table Editor/UIB Editor

This may not be so "user friendly" since it actually requires you to search for some entries then manually type stuff but I can guarantee it's safer, so I recommened using this method instead of Shai-Hulud's.
Please pay attention to the entries: if you are running 1.06 version of the game, you have to scroll down and find the 1.06 map entries in text.uib, otherwise the map will not be activated properly. I have explained it in the tutorial, just pay attention :)
