Game Genie Code Vault

NOTE: I made a few changes. First, I got rid of the categories and just lumped them all together. Second, ones that were discovered by me are marked with an * because they're probably not found anywhere else. Read on!
Last updated: April 23, 2006.

STAGEO - all enemies throw hammers! (use this for a challenge!)
VALLEY - enemies only move left.
KIPAXI - weird castle levels
OZTLLU - Mario mimes walking against the wind when you press A.
YPAIIU - always get 3 fireworks.
NAPSIN+AETVEN - once you get a fire flower, press B and all the enemies on the screen die!
NNPOPK - Sky world - fall in a hole and get coins!
*KTIPEK - Black and white world except for pipes and trees are orange. Mario walks until he reaches a pipe and is stuck.
*IIPOPK - Brick floor with no background
*NNINTV - Beep starts each level. Land music is the same, but no music plays in caves, and a high-pitched never-ending beep in the water worlds.
*NATUTV - Slow Mario, jumping on enemies kills you!
*STYYLY - 1-1 has weird music. At the end of level 1-1, end music plays, game freezes.
*_TPAUL - Fill in space with different letters and you get a variety of different squares as your background.
*POEYPO - Mario is invincible, but you can't see him!
*YEAAAA - This makes the stuff that happens in the PIGPOG code look normal. We're talking weird stuff, background color changes, numbers flooding the screen, making the game slow down a LOT. If at first, it freezes after a little bit, try it again because the stuff it does is random.
AAGOPO - Mario can swim everywhere, and you start some worlds about 1/2 way thru. By changing the first letter to P,Z,L, or G, you can adjust where you start the levels. If you change the first letter to a "G", then you will start some worlds right next to the flag pole! (and mario can swim!)
PAZSKO - Once you turn into Fire Mario, you will always be able to shoot fireballs, even if you turn small again (until you die). Also, if you touch an enemy, it will make you power-up!!
AETLTK - Jump as high as you want!
VVAANY - Timer counts up instead of down!! This code basically gives you as much time as you want to finish a level. The longer you take to finish a level, the more points you get at the end!!
VTTNYA Mario skates like gumby
VGANYA Mario always walks crouched down
VTLNYA Mario turns big when he walks
UATIUA Mario walks right thru enemies
VGANZA Little mario turns big when he jumps
VGANPA Big mario turns little when he jumps
VTLNGA When little mario walks, he turns big, little, big, little, big, little, etc...
NEPELA Play as Game Boy mario (everything is black & white).
NTPOLE Everything is offset by about 2 inches
NTPOLT Everything is different, plus castle is missing at end so Mario keeps walking forever.
SSASSA Invincibility! Let an enemy touch you and see what happens.
PIGOAP Swim without water (you're always swimming)
*GAYSUK - On a ledge, get a running start and you can run off the ledge in mid-air!
UATIUE Invincibility! Mario walks right thru enemies.
TAZUIG Mario has some hang time when you jump while running normally
SSSAPE Drunk Mario.
AETLIK Super mega jump, standing start only. 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!
GETLYG Mario has semi lunar descent. This means that when you jump, you float back to the ground instead of just droping. This code works for standing, running, or turbo running.
SYLOGK Mario swims instead of walking in all blue background worlds.
YETLYG Mario has variable jump heights. Sometimes he jumps high, sometimes low.
EAZLIT Mario can't shoot
ZZZLTT Permanent fire power
TELLEY Mario Falls up.

PXTLLX-AATLGZ-SZLIVO Always stay small and you cant get hurt.
SXUASX Whenever you hit a box or break a brick it looks like it's still there.
NXUASX Whenever you hit a box or break a brick a green box appears.
VVVEEP Dark monsters and coin boxes don't flash.
PKAOZP Always stay mega invincible but sometimes you die when you beat a level on a flag pole.
NNVKEE Monsters follow you but can't hurt you.
STATIO Sometimes Goombas act weird.
LUGLUG Mushrooms and stars lug around.
PEOAAA The game goes directly to Duck Hunt.
ZIOAAP Weird Mario but you can only move back and forth at one spot.
UEXLEY When you jump and hit something it appears in the sky.
GAUAXU "Cs" appear.
YAUAXU "Fs" appear.
OSLEXY Mushrooms stars and enemies fly! Fire flowers float!
ANTOSA - Ever have trouble remembering which pipes you can and can't go down? Well, this code solves that problem! The pipes you can't go down are upside-down, the pipes you can go down are normal.
PIATYP -Enemies can go thru pipes, walls, and blocks! Mario (as usual) can't go thru pipes, walls, or blocks. This code really changes the way you play SMB.
TSPIIT All enemies are gone!
AALLEY Most enemies are frozen!
APZPVG Mixed up enemies
SEPPIS Long row of coin boxes
XVXOKK Different enemies
_KGEKG plug in anything at first part of code to change colors of bushes and pipes.
AUNYGP Enemies go wrong way and are in wrong spots sometimes
STAEXZ Weird blocks and coins
GAAGGA Falling coins
GOATSZ Goombas are weird when hit by fireballs

GAPPOI 1 Koopa, reset pipes, no enemies in 1-1
GPPPOS Lots of koopas, reset pipes, strange background
GPPPOI More Koopas than the code GPPPOS gives
AKKOOT + IEEGGP + NULTKA Turns Enemies into Toad
POEISA Touching an enemy powers you up (and gives you 1000 points)
YSAOPE + YEAOZA "Level Select" code!! 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".
LEAOGK Opens route to minus world! (at end of 1-2)
NTPOPT Almost a solid row of coin blocks and tubes in 1-1.

YLAOKK + ILAPKK 6 or 7 new worlds! (always swimming)
AXAENT Invisible worlds. See how good your memory is.
ASTETE Play at night
EGAPEI - World 1-2 is weird. Enemies delayed, go in end pipe and begin over again.
TTPOZG 1-1 has stuff from other worlds.
TPPOZG 1-1 is very different and much longer than normal. Also, if you die, when you come back, your at the flag pole, and after you jump on the pole, you keep on going past lots of neat stuff, and then you fall down a hole and the game starts to freak out. (It's never the same.)
SAGOOK The water level, only you don't swim. The coral is composed of the bricks, and there are goobmas, turtles, and bullet bills. The background is the water, only light blue, like sky. The pits are impossible to cross without a high jump code (since they were meant to be swam over). I think after you get to the pipe, the next level crashes.
