Dark Castle (Genesis)
This game has a hidden level select.
Someone at Three-Sixty Pacific thought it'd be a good idea to try porting a great Macintosh game to consoles, without mouse support.
Pause the game, then press B, C, A, Up, Start, A, A to add extra options to the pause menu, one of which (Return to Screen) is a level select.
