All missions and medals
Create a new pilot and enter FongFong as a name. Start the game, then immediately exit. Enter the "\lucasarts\xwingalliance\" folder and delete the "fongfong0.plt" file. Start the game again. All missions, intermission sequences, and medals will be unlocked.
Cheat
Note: this only works with X-Wing Alliance v1.00!
As I was messing around with the settings of this truly awesome game I found a cheat/bug which you can exploit.
Press ESC during the game (favorably in the Concourse / aboard your Family Transporter). Go to the 'General Options'. At the bottom you can set the preset values for 'F11' and 'F12'. Now set the 'Beam Level' to Zero.
Note: This only works when you don't have a Beam Weapon installed ! (tnx 2 LoX)
When flying press your new-edited F11-key (or F12 whatever) and you're in for a surprise. The game seems to allocate energy for the Beam Weapon even if you don't have one installed - and since we set the Beam Recharge Level to Zero you are getting that energy added to your engines !!!
This will give you an edge especially with the slower ships (e.g. Y-Wing, CORT's ...).
Cheat mode
Press [Esc] before starting a mission and enter the "General Options" menu. Then, enable the "Tour Invulnerable" or "Unlimited Ammo" options. Note: This will result in less points, no bonus points, and no medals during the game.
Hidden picture
After playing a combat simulator skirmish or combat engagement, a screen will appear with your score and those of any other players. At this screen, press [Shift] + [Ctrl] + [Alt] to view a hidden screen.
