Warp Zone, Play as Luigi, and More:
May of the old tricks for the original Super Mario Bros game on Nintendo
work on the new Game Boy Colour version. For example, the warp zone
found in World 1-2 is still intact!
Warp Zone:
Go to World 1-2 and find the second set of moving platforms. Get on these
platforms and ride them until you reach the top. Then jump up and to the right. You will land
on the top bricks of the level. Run right and kepp going until you reach an opening.
Fall down the opening and you'll see three pipes
that will allow you to automatically warp to worlds 2, 3, or 4!
Max Out Lives:
Go to World 3-1 and get to the end of the level where the staircase
of blocks leads up to the end-level flagpole. Two turtles will come
down the steps and you'll have to avoid of get rid of the first one.
Now, you will have to get the second turtle shell between one of the
blocks and Mario's body by jumping on it to make it bounce off the
block and Mario multiple times. Once you do this correctly, your
score will increase and eventually turn into 1-Ups! This way
you can max out your lives!
The Lost Levels:
Basically, you must get the number-one position on the "Ranking" screen.
Then on the title screen, select the Luigi icon for an entirely new game-
Super Mario Bros 2: The Lost Levels.
You Vs. Boo:
You must get a minimum score of 100,000 points. On the title screen,
select "Boo" for the "You Vs. Boo" bonus levels.
Five Extra Lives:
Note: This only works on a new game. Select the "Toy Box" option
at the main menu screen, and then choose the "Fortune Teller" option.
Keep choosing cards until you get the Extremely Lucky card. This will
give you five lives. Return to the main menu and choose to play the
original levels. Start a new game to begin with ten lives instead of
five.
Play as Luigi:
Press the SELECT button at the Map screen before you begin a level.
This will let you play as the green plumber instead of the red one.
