Super Mario Bros. NES Cheats
Hold A at the game over screen. While keeping that button held, press Start when the title screen appears. Alternatively, hold A and press Start(2) at the title screen or hold A + B and press Start at the game over screen....From: tonyps2123
Beat the game first and if you do not switch off the console, you will go back to the title display. There, you can push the B Button to start as wanted in World 1, 2, 3, 4, 5, 6, 7, or 8....From: Forgiven
Hit the flagpole at the end of a level when the last digit of the timer is 1, 3, or 6....From: seth4
Go to any Boss level, except for the final level. Make sure that Mario is big when reaching the Boss. Jump on the little axe object so you hit the Koopa (Boss) and the axe at the same instant. You will flash as you were hit but will remain as Super Mario. On the next level, get a mushroom and it will actually make Mario small. Finally, get a flower...From: KarKi
In levels 1-1 and 6-2, wait to collect the Starman at the last possible moment, and run through the rest of the level. If you are still flashing when you enter the castle, the music will change to the Mario theme song....From: Momy
Break the second to last and third to last blocks from the edge, above the exit pipe in World 1-2, while you are Super or Fire Power Mario. Then walk as far right as you can, then as far to the left. Repeat this procedure until you can see the edge of the warp pipe on the right edge of the screen. Stand with your trailing foot hanging over the edge...From: Mia6296
There is an easier way to get to the space beside the exit pipe in world 1-2. Before reaching the exit pipe, take the platforms up to the very top of the screen. When reaching the top, jump to the right. If done correctly, Mario (or Luigi) should land on top of the bricks. Run to the right to find the warp zone to levels 2-1, 3-1, and 4-1. Use the ...From: anny
Go to the first pair of platforms. There will be three blocks floating in the air to the right of the platforms. Stand directly under the space to the left of the first block and jump. If done correctly, you should have made a block under that space. Then, stand directly under the second block and jump. If done correctly, you should have made anoth...From: Billy
Use the "World -1" trick, but instead of going immediately down the first pipe, immediately go down the middle pipe. If done correctly, "Welcome to Warp Zone" should suddenly appear and a "5" should also appear over the pipe you just entered....From: WhiizzKiidd
Stay on the ceiling the entire time to find a warp to world 5. It will appear just like the warp in World 1-2 except it only has one tube....From: b7RKli4l
Go to the end steps. Kill the first duck, if you have the firepower. If not, jump over the first duck. Stand on the third step going up. When the second duck is on the step in front of your character, jump straight up in the air. When you hit the duck, repeatedly press A. If done correctly, you should keep jumping on the duck. After jumping long en...From: Ibwuhhmt
There is an island toward the middle of the level. The island has a pole with a brick above it. On the right side of this island there are turtles. Hit the first turtle twice so that it goes to the right (and hits the other turtles). This will give you an extra life. However, this can only be done a certain way. You have to wait slightly after you ...From: dubz
In World 4-2, enter as small Mario. Hit the box after the several ledges and run all the way to the left edge of the screen. Hold this button the entire time. When Mario gets the mushroom, he will appear to do a moonwalk....From: SarahMarie777
In world 3-3 (and possibly in world 7-2), there are two platforms that move up and down when they are stood on, at the end before the flag. Stand on the left platform until the last possible moment, then jump to the right platform. Wait again until the last possible moment to jump to actually go over the flagpole. If done correctly, you can keep wa...From: tgz20
In World 1-1, hit the brick that has the star in it found halfway through the level. Before it goes off-screen, hit the highest "?" block. When the item comes out (mushroom or flower), the star will disappear. This also may be done in other levels....From: Wactchapy
Whenever you go to any of the ship stages, there is a Boss at the end of each ship. When you defeat the Boss of the ship, there is a wand that falls from the sky and it is usually straight. Very rarely, the wand falls on one of the cracks in the floor and it turns sideways....From: nfs720

Why is there a mini "trampoline" on the upper level of world 5-castle? When you jump on it, poor Mario just hits his head on a masonry ceiling. In the center, I can jump kick a couple of tim...
