There are no cheat codes in the shareware episode of Stargunner. There are a bunch of them, however, in the full registered version.

To enable cheats, press the "Pause" key (you must be in pause mode to type in cheat codes), followed by "imabigcheat". You will hear a bell sound when cheats become enabled as well as see your score disappear. You cannot enter a high score if you cheat.

  • "Customer Cheat" means it's the cheat given out with the registered version of the software.
  • "Debug Mode" means it's an unsupported cheat mode.
  • "Tech Parameter" means it's a code that does something, but really isn't a cheat, it's more or less there to help Apogee Customer Support.
  • "Misc Command Line Parameter" is the same type of thing as Tech Parameter.
Cheat keys are not officially supported by Apogee. If you use the debug keys, Apogee cannot provide any support, since this alters game performance to a state where our standard support comments and issues might not apply. In short, using cheat keys can cause the game to malfunction or crash. Use at your own risk!
