Found a couple of Wing Commander-adjacent items at eStarland, which is a hidden treasure for retro gamers in Chantilly, Virginia. The ‘Game Guru’ is a Game Genie-style tool for 3DO games that specifically supports WC3! 3DO Game Secrets is a book with info on how to access the game's debug mode.
Super Wing Commander has a wicked debug mode.
DEBUG MENU: Go to the lounge screen. Press and hold the X button, then press B, B, C, C, A, A. You should hear a sound. Release the X button, press and hold the L and R buttons, then press the P button. The debug menu appears with a multitude of options.
Exit System Menu: Return to the lounge.
Change Sound Volumes: Change the volumes of every sound effect.
Change Music Levels: Change the volume of the background music at every point in the game.
Play Movie: Watch all of the game's video clips, including several that were removed from the game but left on the disc. (FILM.MOV and UID.MOV even have a live female actor.)
