Lets you start on any world you want! Here is how to get to the level select screen: When you first start out, you are in a new world (0-1) and you have to finish this level to get to the level select screen. Here's how: Swim (yes swim) past the first pipe you see and keep going until you see some water at the bottom of the screen. Swim over the top of the blocks that are above the water, but not too far. Then swim down and backwards a little to drop down through the little opening in the blocks that lets you get to the bottom of the screen. This part is very important because if you aren't at the bottom part of the screen, you won't be able to finish the level. Once you get to the lower part of the screen, just keep going to the end of the level. When you get to the end, it will say "Thank You Mario, but our Princess is in Another Castle". To get the game to continue, you have to press "B". Now your at the "Level Select" screen! Just press "B" until you see the world you want (at the top of the screen), and then press "Start".

Basically, just add 6 zeros to what the item was worth. So if an item was worth 100 points, now it's worth 100,000,000 points. Actually, what this code does, is add 4 more zeros between the score and the number of coins collected. So the score counter has 12 digits, instead of only 6. The last two digits are really the coin counter, but looks like it's part of the score counter. The code does have one little glitch. On worlds that have a light background (like 1-1), the score is a little hard to see. But on screens with a dark background (like 1-2, coin rooms, etc.), the score shows up just fine. So if you are having trouble seeing the score in the first world (1-1), just go down the tube to the coin room, or loose a life, or finish the level. The score shows up fine in 1-2.

If you try to jump while running, you can barely jump at all. But jumping when standing still, lets you jump as high as you want! If you hold down the button for 3 minutes, Mario will keep climbing higher, and higher for 3 minutes! The clock even stops running! Then, if you let go of the button, it will take Mario 3 more minutes to fall back to the ground! Also notice that this code is completely different than any of the Galoob jump codes in the book.
