Super Mario Bros. Cheats For NES

Unlimited 1-Ups (lives)

To get unlimited 1-ups, go to world 3-1 and head towards the end of the level. At the end of the level, you will see two turtles coming down the stairs that lead to the flagpole.  Hit the second turtle to make him stop coming down the stairs and keep jumping so your character doesn't hit the ground. The timing here must be perfect or you will end up sending the turtle flying. If done correctly, you will be rewarded with continuous 1-ups if you're able to keep going. 

Warp Zone 2, 3, 4

This allows you to skip to world 2, 3, or 4. While you're in World 1 - 2, head toward the end of the level where you will see the second set of moving platforms. These particular platforms will be moving in the up direction instead of moving downwards like the previous one. Ride a platform all the way up till you can jump onto the blocks at the top of the level and walk right till you approach three pipes. Each one will take you to the world of the corresponding number, the options will be world 2, 3, or 4.

Word 1-2 Pipe Glitch

In World 1-2 there is a glitch that will take you either to World -1 or you can use it to get to World 5-1. At the end of the level in 1-2 you will come to a pipe that leads you to the end-of-the level flagpole, instead of going through the pipe you can glitch through the top of it. This is the same area that takes you to the warp zone of worlds 2, 3, and 4 but using the glitch will make these pipes take you somewhere else.

To perform the glitch, break the second to last block above you, then sand with one foot hanging off the pipe. Next, you have to duck, and while ducking, you're going to work to jump backwards toward the pipe without breaking the block farthest to the right. Repeat this till your character glitches through the wall and you can walk to the warp zone secret area.

Warp Zone 5

In World 4-2 there is a hidden warp zone that takes you to world 5. In order to get to this hidden warp zone, head to the end of the level until you see the last set of platforms moving in the up direction. Take these platforms up to the top of the level and walk to the right untill you come across the pipe labeled "5" leading to world 5.

Warp Zone 6, 7, 8

In World 4-2 when you come up to the first set of platforms that are moving downwards, there is a hidden beanstalk in a block right across the hole the platforms are moving down. You will see 3 random blocks in a row next to a pipe, they will have hidden blocks underneath them, so make sure not to jump and hit the first one all the way left. Start from the right and hit the first two invisible blocks underneath to give yourself access to the beanstalk. If you take this beanstalk, it will give you the options to warp to World 6, 7, or 8. 

Trigger Fireworks

At the end of a level that contains a flagpole there is a way to trigger a secret fireworks display. Most people will trigger these and not know exactly how or why it happened. To trigger the secret fireworks, at the end of the level you must jump on the flagpole with the time remaining ending in a 1, 3, or 6. If the time remaining ends in a 3, then only three fireworks will display and it the time left ends in a 6, then you will see the max of 6 fireworks.

Hard Mode

Once you beat the game you will be able to unlock hard mode. This turns all enemies into Buzzy Beatles, making the game more difficult.
