Wing Commander: The Secret Missions (SNES)

Wing Commander: The Secret Missions is the SNES version of the first Wing Commander expansion.

Debug menu
Like the original, there is a debug menu that allows you to select a starting mission, toggle invincibility, and listen to the music and sound effects. To activate it, press L, R, Start, and Select on controller 2 simultaneously at the title screen.

The options are identical to those in the original game's debug menu. Similar menus also appear in Mario is Missing and Mario's Time Machine.
