You could just use the second line if you like, though you'll still start the game looking small. When you're hit, you'll actually get big, heh. If you're hit again, you'll get small, and if you're hit again, you'll get big again, and so on. It's probably better to just add the top line, if only for looks.

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.

This one is by far very unusual. It doesn't directly affect the stage, but when you kill an enemy it will. When you squash an enemy when its paired with another, it will fly around the screen real fast & land some where else. Most of the time it'll land off screen, but there are times where they land just above you or on you. If you are at a part where you're stuck or it just keeps repeating, don't worry. Just die & then when you start your next life, everything will be back to normal until you kill another enemy.

Certain packs of Goombas (the waddling muffins) are transformed into large groups of Koopas (the smiling turtles). The Goombas that become Koopas, and the number of Koopas in each pack, seems to be the same every time. In general, about 1/2 to 1/4 of the Goombas in a level will change, and there will be 2X to 3X as many Koopas as there would have been Goombas.

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 levelselect screen. Here's how: Swim (yes swim) past thefirst pipe you see and keep going until you see somewater at the bottom of the screen. Swim over the topof the blocks that are above the water, but not toofar. Then swim down and backwards a little to dropdown through the little opening in the blocks thatlets you get to the bottom of the screen. This partis very important because if you aren't at the bottompart of the screen, you won't be able to finish thelevel. Once you get to the lower part of the screen,just keep going to the end of the level. When youget to the end, it will say "Thank You Mario, but ourPrincess is in Another Castle". To get the game tocontinue, you have to press "B". Now your at the"Level Select" screen! Just press "B" until yousee the world you want (at the top of the screen),and then press "Start".

If you use the code above then your character (Mario or Luigi) will start out small. If you have any experience with the always stay big code, you will know that it does NOT work until you get big--ie get a mushroom. With this code, once you get big, just as with the always stay big code, you will never die unless you fall in a pit or run out of time. However, you do not stay big!!!!!! The first time you die, you will change from big to little, as usual. The second time you die, you will change from little to big Other cool things you can do with this code. *Have fire power when you are small. *You don't lose your fire power or invincible power when you die from enemies (that is when you change size). You do, however, lose those powers when you fall in a pit. Easily change size just by killing yourself.
