Classic NES Series: Super Mario Bros. Cheats

At the end of World 4-2, jump onto the top of the screen and keep walking until you drop into a room with a warp pipe. It leads to World 5.

Well this secret is so easy. At the very end place of world 4-2 (where you can see the pipe going to the flag) jump on the long pipe and break the brick above it and go through the end and you can see the pipe going to the World 5.

This is a pretty commonly known secret. If you touch the flagpole of any level with either 1, 3, or 6 seconds left on the ones place of the timer, you will get that amount of fireworks. For example, if you touch the flagpole with 126 seconds left on the time, you will get six fireworks!

To warp to World 6,7 or 8 during World 4-2, go to the place where three blocks are can be seen (where a pipe can also be seen). Jump below the third block where you can reveal a secret block but be careful on jumping below the 1st block because you can't break it thus going to the secret warp world unless you are a small Mario. Then step on to it and break the 2nd and the 3rd block. After you have done this, go down, then jump again below the second block now (it should have been broken now). The position of the two revealed blocks must be a stair from right to left. Anyway, step on to the 2nd block then braek the 1st block and there you can see the vine going up. Climb until you reach the day light again. Get some coins if you wish and you can now see three pipes like in the secret warp Worlds 2,3 and 4. Go down your desired pipe.

To warp to Worlds 2, 3,or 4 during World 1-2, go to the end where the 2 platforms are rising, get on the first platform, and use it to jump onto the highest structure in the middle, then jump on the next rising platform, but this time, when it reaches the top, jump onto the TOP of the level. Walk foward and drop down the small jump, and you can now warp to Worlds 2, 3, or 4 by going down the desired tube, and pressing down.

In world 4-2 you will come across a moving platform. Jump past the platforms until you see a ledge with three blocks. Go just left of the first block and jump, you will reveal a secret block. Go over under the second block and jump (rember to leave the space under the first block empty) and jump under the third block to reveal another hidden block. Jump on top of the blocks and start destroying the blocks until you find a vine growing out one of them. Climb up the vine to reach an area with lots of coins. go right until you find some stairs. jump on top of them and walk rigth. Now you can warp to levels 6, 7, and 8.

In order to get fireworks to go off after you beat a level, simply finish the level when the last number in the Time is either a 1, 3, or 6. The number of fireworks you get depends on that number. So finish a level with 106 remaining, and you'll get 6 fireworks to explode. Plus, you get bonus points for each firework that goes off.

If you ever find yourself with a Game Over, and you would like to continue from what world you were on, wait for the 1/2 Player select screen, then hold A and press Start. Now you will start at the first level of the World in which you obtained the Game Over from. For example, if you got the Game Over from 7-3, you will start over again at 7-1!

If you run out of lives and want to continue then at the game over screen press and hold A then press start at 1 player (or 2 player) and you will start at the beginning of the world at which you died!

If you just walk along the sea floor, Bloopers will never be able to kill you because they are forced back up just before they hit the floor(or you).
