8 SECRET HIDDEN LEVELS In Super Mario World (Cheat Code Access)

Did you know there are levels you can't access in Super Mario World For Super Nintendo unless you use a Game Genie Code or Action Replay to access it? 7 of these levels are pretty short but the 8th secret level is Bowser's Castle in which you can fight most of the bosses in the game. It would have been cool to have a Boss Fight room unlocked after beating the game. A lot of these levels seem to be "Test" Levels that the developers left in and only can be access with Game Genie Codes (or maybe other ways as well?) I also want to call this "Super Mario World: The Lost Levels"
