The Golden Torizo code is a leftover debug feature in Super Metroid.
The code must be inputted using the controls in either room before the Golden Torizo, and it will not work if the Torizo has been destroyed. To perform this code, the player must hold the A, B, X and Y buttons all at once as they enter the battle room. Doing so will grant them seven Energy Tanks (700 units of energy), three Reserve Tanks (300 reserve units of energy), 100 Missiles, 20 Super Missiles, 20 Power Bombs, and every item in the game, except for the Screw Attack and X-Ray Scope (the former can be obtained depending on what entrance to the Torizo room is used). Notably, it enables both the Spazer and Plasma Beams, which will crash the game if fired unless the player enters in Morph Ball mode, or if fired when facing the door.
