You need to be Raccoon Mario to do this. When you enter the World 2 Fortress, don't attack the first Dry Bones (the skeletal turtle) you see. Instead, lure it over to the other two Dry Bones a few screens ahead. Now, jump on the first one, and use the raccoon tail to flutter onto the next one, and then the final one. By then, the first one should be back on its feet. Keep repeating the process for infinite lives.

Attract Lakitu to the pit underneath the Venus Fire Trap. Next, launch a Koopa shell between the two wooden blocks. Now, as Lakitu launches Spiny Eggs, the Koopa shell will instantly destroy them. Accumulate enough points, and soon you will receive infinite lives. (NOTE: The max amount of lives you can get is 999.)

Whistle 1- On Level 1-3 when you get to the end of the course you will find a white block. Hold down while on top of the white block until you go behind the scenery. From here run to the end of the course and you will be transported to a room with a magic whistle

Whistle 2- On the World 1 Fortess, when you come across the first Dry-Bones, there will be a [?] block. Hit this to get a leaf. As Racoon Mario, knock out the dry bones and fly up the ledge until you start walking along the top of it. Continue going right whilst on top of the ledge until you stop moving. Press up to be transported to a room with a Whistle

Whistle 3- On World 2 after you have collected the Hammer from the Hammer Brothers go to the top right corner of the world map. Use the Hammer to break a rock leading to a secret passge. In here there is a Firs Brothers, beat them to get the Whistle

In World 5 (Cloud World), the first available mushroom house has a Tanooki Suit. Get it and beat levels until you get to the cloud part of the world by beating the spiral tower. The game offers to save your game. Save it, then get game over. When you continue, you keep the Tanooki Suit you got at the mushroom house, and the mushroom house has returned! All of the other levels remain defeated as well, though the spiral tower remains standing, so you cna beat it and save your game, get game over, and get another Tanooki Suit each time! The suits make good replacements for leaves, mushrooms, and useless items (like music boxes) in your item list.

Glitch only works for World 5 due to the ability to beat the spiral tower as many times as you want and save after each time.

Defeat the Koopaling at the end of an Airship (Worlds 1-7) while wearing either the Frog, Tanooki, or Hammer Bros. suit and receive a special message from the King.

In most levels, there are multi-colored blocks held up by screws. With the white ones, you can drop behind the scenes to escape enemies or find secret exits by holding down on the d-pad for 5 seconds. In World 1-3 towards the end of the level, drop behind from on top the white block and run behind the black curtain. You will uncover a hidden mushroom house which contains a warp whistle.

Beat the game clearing every single level (90 in total). Once Bowser is defeated, save and you will be brought to a World Selection screen where you can jump to any of the 8 worlds. All locked doors will have been unlocked and you can freely visit any stage/bonus stage/castle/etc.

For every 1,000,000 points you earn, a star will appear above the title Super Mario Bros. 3 (where you select between Super Mario Bros. 3 or Mario Bros.) You can earn up to five stars.
