Super Mario Bros.

Wii Virtual Console version: World select:
Press B at the starting screen to increase the World number that the game will start on. Each time you press B will increase the starting World. For example, press B(7) to start on World 8-1. Note: You may first need to complete the game.

Continue game play:
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.

Hint: Quick game completion:
Take the World 1-2 and the World 4-2 shortcuts. You will go to World 8 and can easily complete the game. Note: If done well enough, you can complete the game in five minutes.

Glitch: Disappearing Star:
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.

Glitch: Toad talks to no one:
When you get to any Boss except 8, small jump over the Boss stand next to the axe. When he gets close, jump on the axe and his head at the same time, as if you were trying to get fire power while small. If you land correctly, you should die but will not lose a life. The screen will show Toad saying "Sorry Mario, but our princess is in another castle" will appear, but he will be standing alone and it appears as if he is talking to himself. You will then move on to the next stage.

Glitch: Pipe:
In the World 8-4 castle, go through the first two pipes to continue to the third area. In the third area, go past three of the pipes, but do not jump over the lava. Stand by the edge of the lava pit, then go back to the pipe before the lava pit (third pipe). You will then be transferred to the next area (underwater).

Glitch: Ongoing level:
On any level, go to where the stairs with the flagpole at the end is located. Go on top of the last stair. Then, sprint and at the very edge of the stairs, jump. If done correctly, you will have jumped over the flagpole and onto the other side. Once there, you can either jump on the pole or keep running. Note: If you keep running you will continue until time runs out and you cannot go back.

Glitch: Become Fire Mario when small:
When in the castle of any world excluding World 8, become Super Mario (mushroom only). Stay like that until the very end of the castle. Getting past Bowser is your next task. Stand near the end of the bridge (where the switch to kill Bowser is found). Allow Bowser to come towards you. Jump and hit both the switch and Bowser at the same time. You should appear to be flashing, yet still be Super Mario. Proceed to the next world. You will be Super Mario. Hit the first block that contains a mushroom or fire flower. It should be a mushroom. Get it and you will turn small. Find another block with a fire flower and get it. You will now be Fire Mario when small.

Glitch: The Minus World:
You must be Super Mario or Fire Mario for this trick. Go to the end of World 1-2, but do not go to the warp zone. Also, do not go up the normal pipe. Stand on the edge of the normal pipe and break the ceiling blocks above, except for the one touching the wall. You just need to clear a space to jump; do not worry about clearing all of the others. Crouch on the edge of the pipe while facing away from the wall. Jump while crouching. While in midair, move backwards so that Mario's head collides with the side of the remaining brick. You should move backwards into the wall. Continue holding whatever direction you are currently using until you pop out the other side. Do not go to the right any farther than you need to in order to go into the first warp pipe. If you go too far, they will reset to their normal worlds. Go into the first (left) warp pipe, and you will go to World -1, the minus world. It is like the first water level, but when you try to leave at the end, you will go back to the beginning.

Note: When follow the steps to go to the Minus World, instead of going into the first pipe, going into the second pipe will send you to World 5 (instead of wasting time going there from World 4). If you go into the pipe on the right, it will also take you to the Minus World.

Glitch: Mario goes through bricks:
In World 4-2 when you are small hit the brick which has the mushroom towards the beginning of the level. Then, follow the mushroom until you are under the bricks. Get the mushroom, and when you are big you will be standing through the bricks. You can also walk through them.
