I think there is a link to the commander's site around here somewhere although the commander doesn't host it anymore it's hosted by someone else but there might still be a link to it there... a script called reveal whole universe which I have been using for a while now. Works great but places the navsat too far up from the center of the sector so the gates aren't shown on the map. You can always alter it to place the navsats closer so the gates will show up though. I included the script with my mod as a cheat script if you have a fast connection it will be easy to download that file and get the script from there.
Our mighty sovereign may she always go before us sailing brightly in the sea of black.
A script that does this can be found at http://x2source.com/forums/index.php?download=113, it will reveal all of the sectors by placing a normal satellite or an advanced satellite in each sector, then it will destroy it. You can control which type of satellite it uses when you run it, and you can also control whether it destroys the satellites or not.
I'm not disappointed in you; I'm disappointed in myself, for believing in you.
