"SFG.cca" is a nearly-complete source code of Star Fleet the Arcade Game. However the second level has since been altered for XB2 testing.

"SFG.exe" is a standalone version from an advanced stage of development. All 5 levels are present but level 5 cannot be accessed from the main menu.

"SFG.gam" is source code from an earlier stage of development, prior to being exported to MMF format.
