Hey, I got the n64 version too, i haven't tried the computers, which is probably better 'cause you can use the at-st on any level man that stinks that it can't be used the same way on n64!
I did find a level editor for x-wing that is so cool to use, go to
www.avault.com) (
http://www.avault.com) and go to cheats & hints and go to games starting with x an go down to x-wing and download the mission builder/editor it's the one with the 10 after the letters. also if you do not have anything to unzip it with go to
www.interplay.com) (
http://www.interplay.com) go to interplay a-z down to descent series and choose descent and go down to where it says pkunzip and download it so you can unzip stuff.
The editor is neat i just got it today and am trying to figure out how to use it, it IS user friendly.
