Go to World 1-2. At the pipe that leads to the flag, break two blocks so there's
one at the end touching the pipe. Now duck and jump backward toward the brick (don't
break it!). You should go through the wall and pipe into a warp zone. Jump down the
first pipe you see and you will be in the Negative World (-1)!
- Shoot fireballs as small Mario Go to either 1-4, 2-4,3-4, etc. and get to Bowswer.
Make sure you are Big Mario and try to jump over Bowser or run under him. Stand near
the Axe and Bowser will start to walk towards you. As he gets near you, jump high,
and touch Bowser and the Axe at the same time. If you do it correctly, you will hear
the sound as if you were to shrink, but you will just flash and stay big. Go to the
next stage, and get a Mushroom. (Yes, there will be a Mushroom instead of a Fire
Flower.) When you touch the Mushroom, you will shrink. Then get a Fire Flower, and
you'll have Fire Power as small Mario. (Note: after you do the Bowser/Axe trick,
enemies that touch you will be able to kill you when you are Big Mario. When they
touch you while you are small Mario after getting the Mushroom or Fire Flower, you
will turn back into Big Mario.)
- Access 5-1 from 1-2 To access this warp, you must be Super or Fiery Mario. Go to
the pipe at the end of the level and jump on top of it. Jump up and break the block
over top of the part of the pipe farthest left. Then, position Mario on the edge
of the pipe, with one foot hanging off the edge. Duck, then jump backwards as far
right as possible. If done just right, Mario will slide through the pipe and the
bricks. Walk over to the warp zone area and enter the middle pipe. This pipe will
take you to world 5, level 1. The same area can be acessed from a pipe in the same
place in 4-2. However, this is meant to be a warp zone to 5-1, whereas the 1-2 warp
to 5-1 is a glitch. After completing the jump trick in level 1-2, you can also go
down either of the other two pipes, both of which will take you to Minus World -1.
Get 99 lives to have Mario not wear his hat. If you complete a level with 99 lives,
Mario will not be wearing a hat at the map screen or the next level. He will wear
a hat again if his lives drop below 99.
To get a mushroom house to appear in multiplayer, you simply need to clear the level
when the time has the same 2 end digits next to each other when you touch the flag
pole. Examples: 544, 322, 411. Depending on the two end digits, you will make different
mushroom houses appear at the start point, as you would in single player when you
save a Toad, only the digits are mostly red mushroom houses. Two zeros at the end
will get you nothing. When you do this, you hear the original Super Mario Bros. level
clear music and see a number of fireworks depending on what the last 2 digits are.
1 firework for 11, 2 for 22, and so on.
Gold Mushroom House Get Toad to the end of the level and hit flag when the last digit
of the time ends in 7, 8 or 9
Red Mushroom House Get Toad to the end of the level and hit flag when the last digit
of the time ends in 4, 5 or 6
Green Mushroom House Get Toad to the end of the level and hit flag when the last
digit of the time ends in 0, 1, 2 or 3.
