Cheat mode:
Find the file called sfbspc13.txt in the assets\specs\ game sub-directory. Open the file with any text editor and change any of the fields to add cloaking ability, modify engine power levels, add shuttles and fighters, add/change weapons, modify shield levels, and much more. Be sure to save the original sfbspc13.txt in a safe place before modifying it so you can return to your original configuration. If you play a multi-player game, make sure that all players have identical sfbspc13.txt files.
