Super Mario Bros. 3/Regional differences

Super Mario Bros. 3 has several differences in the Japanese (Famicom) version and American (NES) version. They are:


 * The Japanese version has an iris-in effect before a level starts, and then an iris-out effect after it. The American version has only an iris-out effect.
 * In the Japanese version, Fire or Raccoon Mario will become small Mario after one hit. In the American version, Fire or Raccoon Mario will only go down to Super Mario.
 * In the World 1 Fortress, in the room with the spiked ceiling, the Japanese version has 3 blocks after the door. The American version has the wall immediately after the door.
 * In the Japanese version, when the king of a world is transformed, the room has 3 columns and Mario starts out on the left. In the American version, there are 2 columns and Mario starts in the middle.
 * In the Japanese version, Frog/Tanooki/Hammer Mario will have a suit fly off in response to a hit. This suit fly off was removed in the American version.
 * In the Japanese version, if Mario uses a warp whistle while in the World 3 canoe, Mario and the canoe will go together into the Warp Zone and Mario can go into the water the island is inside, and he's stuck unless he uses another warp whistle. This was fixed in the American version; Mario alone will go into the Warp Zone.
 * In Level 5-1, the Japanese version has a pipe that must be entered before getting to the goal panel, making an unnecessary glitch possible. In the American version, the pipe was removed and the goal panel was moved to the area where the pipe was in the Japanese version.
 * When Mario has a Kuribo shoe, in the Japanese version, he will become small Mario after a hit. In the American version, Mario will lose the shoe, but remain in the same power-up condition he was in before the hit.
 * In the World 8 Battleships, it is valid to swim under the battleships. In the Japanese version, if this trick is done, it is possible to get back up only with a Frog Suit or P-wing because the wall is too tall otherwise. In the American version, the upper right corner of the last battleship was removed to make it possible to get back up.
