Level Warps
Warp to World 4
: In level 1-3 go to the area just before the brick background. Pick up the plants until you get a bottle. Then go past the brick background until you find a pot and throw the bottle on it. Go through the door and down the pot into World 4.
Warp to World 5
: To warp to level 5, first get to level 3-1. When you enter the first door, fall all
the way down. You have to be in the middle as you fall. When you stop, you
will find a platform with a door. Enter the door, then look for the potion in the grass. Pick it up, then throw it on the ground, enter the door in cyberspace, and go into the vase and you will be at level 5.
Warp to World 6
: In level 4-2 In the area with the whales find a bottle and throw it on the next pot. Enter the doorway and go down the pot into World 6.
Warp to World 7
: Work your way to level 5-3. (It would be a good idea to choose Luigi for this level because of his superb jumping skills.) Go up the ladder at the beginning of the level, and then jump up onto the ledge above the ladder. As soon as you get on top of the ledge, grab the first grass on the right. It is a potion. Use the potion and go through the door. Now, while in sub-space, go down through the jar and voila! Now youre in Level 7!
Instant Reset
To trigger the games built-in soft reset and restart the game without using the power switch, simply hit the following buttons at the same time: Select + Start + A + B.
Lots of Lives in 1-1
Want as many extra lives as you can be bothered to collect? On World 1-1 at the right hand end of the level, enter the upper door into the cave with the line of spiky jobbies (easiest to do this with Luigi, as you can just jump up to it without having to go the long way round). To the left of the spiky things are three plants. Pull up the right-most plant to reveal a giant turnip, and throw it at the bad guys. If you kill them all with one shot, you get an extra life. Leave the cave, re-enter it, and do it all again until you have enough lives to keep you going...
Make Birdo Bald
When you fight a green or red Birdo, jump on her head and pick up her bow and throw it away. Voila! Bald Birdo. Note: this doesnt work on all Birdos in the game.
Sleep Mode
So youre in the middle of playing Super Mario and the telephone rings... Or lets say you feel the sudden urge to check IGN for new GBA stories, but youre in the middle of a level -- what do you do? How about putting your GBA to sleep to preserve batteries? Press the Select and R buttons at the same time and the game will drop into deep sleep. To wake it up again, press Select and L.
99 Lives
In world 5-3 come up to the surface and throw the shell on the ground there, it will keep bouncing off of the walls back and forth. Jump and land on the shell and wait for the birds to drop the bombs. The shell will kill the bombs, and after you get a certain amount you start getting 1-UPS, you can do this forever until you have 99.
