Note: This procedure involves editing a game file; create a backup copy of the file before proceeding. Use a text editor to edit the "sfbspc13.txt" file in the "assetsspecs" sub-directory. The following changes can be done: add cloaking ability, change engine power levels, add shuttles and fighters, change weapons, change shield levels, add more transporters, troops, mines, and more. Note: While playing a game in multi-player mode, all players must use an identical "sfbspc13.txt" file.
