Did you know there are 8 secret Super Mario World levels on the SNES that can only be accessed using a Pro Action Replay or Game Genie? Well neither did I, until recently. Some of the levels are very short and some are unplayable, for example on one level you fall straight to your death and there is nothing you can do. One of the secret levels is Bowser castle where you are required to fight most of the game’s bosses.
Most of these levels seem to be test levels that the developers did not remove from the final game. The Super Mario World levels and codes are listed below.
