In the room where the floor drops open and Mario falls to meet the first Bowser, I found a cheat. Using Mario, run into the room and when the picture of Peach changes to Bowser, jump while continuing to move forward. If you jump at just the right time the entire screen will turn black except for mario and the coin counter. Mario will just kinda stay in the center for a while and then you will appear outside the castle front door. Has this ever been discovered before?
