Play as big Mario with Fire power:
0ZTLLX
AATLGZ
TZLIVO After you enable this code, first become big Mario then run
in to a enemy. Instead of turning small as usual, Mario will remain
big and have Fire power. However, his clothes will still be brown.
You can only lose this ability by falling to your death. Also,
every power-up that you can get will be a star instead of being
a Fire Flower or Mushroom.
Play as small Mario with Fire power:
PXTLLX
AATLGZ
SZLIVO This code allows Mario to remain small with Fire power even,
after being hit by an enemy. After you enable the code and start
the game, get a mushroom. You will still be small. Then, get a
Fire plant and you will have Fire power as small Mario. You will
be small Fire Mario for the rest of the game unless you fall down
a hole.
Always stay small and jump through blocks:
OZTLLX
EATLGZ
SZLIVO This code makes Mario small as soon you pick up your first
Mushroom, unless you fall down a hole. This code also lets Mario
jump through any kind of blocks, even coin ones and allows you
to get to the minus level easier. Go to the end of World 1-2 and
do the "Minus world" trick. Howeve,r instead of having
to break any bricks, just stand on edge of pipe and jump towards
the upper right brick that is directly against the wall. You should
slide through. If not, keep trying. Go down the first pipe you
see to get to World -1.
Stay as Fire Mario:
PZTLLX
AATLGZ
SZLIVO This code allows Mario to remain as Fire Mario, even after
being hit by enemies. The only way to lose it is to fall to your
death. First, get a Mushroom to make you big. Then, get a Fire
Flower to give you Fire power. After that, you will be Fire Mario
for the rest of the game. You can now destroy all the Bosses in
levels 1 through 7 with Fire power to see what enemy is inside
of the fake Koopas.
