For GameShark codes used to access the Debug Menu, see here.

The debug menus are elements of development that were accidentally left in Super Smash Bros. There are four menus: System debug, Battle debug, Falls debug, and Unknown debug. Within these menus, the player has control over various aspects of the game, including unplayable characters, unplayable and single player stages, and more. In order to get to the debug menus, a GameShark device must be used.

System debug menu

 
The system debug menu in Super Smash Bros.

This menu contains various out of battle functions. Within it, one can play every sound and piece of music in the game and view every transition. Sadly, these two options appear to be the only ones that still function correctly. The others appear to do nothing.

Falls debug menu

 
The falls debug menu in Super Smash Bros.

A very unstable menu, the Falls debug menu was most likely used to test the results screen, although it does nothing now. The game may randomly crash upon loading this menu for no known reason. There are 12 options in the menu, 3 for each character. Finish is repeated twice per character. The top one will crash the game if scrolled past 4. The bottom one can go out to 65536. Dead also ranges from 0 to 65536. If "A" is pressed, the battle debug menu is loaded, although changes made to the Falls debug menu appear not to affect the match or results screen in any way.

Unknown debug menu

This mysterious menu appears to have no function whatsoever. It lacks the interface found in the other 3 menus and appears to respond randomly to any button presses, throwing overlapping UI elements on the screen. This menu differs considerably from version to version.

Trivia

  • Super Smash Bros.'s debug menu contains two voice clips of Ness, one saying "PK" and another saying "Starstorm", as well as another clip of Captain Falcon saying "Come on!" (similarly to the start of his Blue Falcon move), suggesting that Final Smashes were originally intended to appear in the game. Masahiro Sakurai later confirmed in an interview that he did intend to implement Final Smashes in Super Smash Bros., and that the voice clips were intended for that purpose.
