Ed the Moogle presents 
Mostly useless Super Mario Brothers 1, 2 and 3 Game Genie codes
by Ed the Moogle
Version 0.42

Don't copy these without giving proper credit. Each and every one of 
these codes is safe (I haven't heard of any NES games being permanently 
messed up from Game Genie codes, except for a few with battery backup, 
which none of these games have...). Many thanks to Adam Blake, who 
inspired me to create these, and I used and altered some of his codes in 
this list. I also used some codes off the Game Genie Code Creator's Club 
homepage, and any thanks not specifically given are acknowledged.

They may be useless, but they're a lot of fun to fool around with!

"The key to a good code is its uselessness." -Adam Blake

A couple of things I've noticed while altering codes. (When I say 
"strand" I mean a group of codes with similar effects, usually taking a 
code and just changing one letter to create new effects, like the ZTEOAK 
family in the SMB3 section).

1) A code "strand" tends to only work with one row of letters. For the 
rest it either doesn't do anything or freezes the game. Most of the 
time, this is true.

2) In a "strand" of codes, you usually can only change one letter. 
Changing more than one often results in a failed code (either a freeze 
or no effects at all).

SMB
Note: I used these codes with a Super Mario/Duck Hunt/Track Meet cart, 
so some or all of these may not work on your version of the game.

Codes created by other people

The following codes are from http://www.angelfire.com/games2/codehut
Not sure what version these work on. Thanks to t_hedstrom@yahoo.com for 
these codes.

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!!

AETLTK  jump as high as you want!  Works while standing, running, or 
turbo running! (No need to enter 3 seperate jump codes anymore, because 
this one code will do the work of all 3 jump codes in the Galoob code 
book.  Plus, this code allows you to jump MUCH higher than any of the 
Galoob codes.)

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.

AEAENT  Mario can jump higher when walking, running, or turbo running!  
Also, he jumps further (only when normal running).

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!!  (On some emulator ROMs, the 
code will make you invincible.)

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.

PAASNO  take no damage from most enemies!  Depending on which version of 
SMB you are using, you may have to either become Big Mario, or jump on 
one enemy before becoming invincible.(NOTE: this code doesn't work 
against the potted plants.)

PAZSSO  similar to above

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".


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!)

VGYOKK  time starts at 900 (instead of 400)

GUAOPO  start with 400 more seconds, and invincibility for the first 10 
seconds.

VTTNYA  mario skates like gumby

LEAOGK  opens route to minus world! (at end of 1-2)

VGANYA  mario always walks crouched down

VTLNYA  mario turns big when he walks

UATIUA  mario walks right thru enemies

OKGASA  everything is invisible except mario & enemies

PAAPIK  new block world

NVAOGK  new maze world

ZLAOKK  new mystery world

PLAOKG  new underwater worlds

SVPOUU  most holes are gone

NLTOGK  mario starts out swimming

VGAOPO  most worlds are different, music is different, you can also walk 
right into the minus world(1-2), plus if you fall down a hole, instead       
of dying, you end up in a coin room!

GSAENT  you can position mario anywhere on the screen (even when he's 
moving) by holding down the "A" button on controller #2.

ASAENT  new hidden world

OLAOKK  new cloud world

NVPOKG  new bonus worlds

NNPOKG  new warp zone world

ONZOGG  new secret world

PLLOVG  new 1-1 world

VTPOZG  newer 1-1 world

PLGOKG  new worlds. Press reset to start in a different world.

VTPOZI  you can jump over the castle at the end of world 1-1 and keep on 
going. Also, going down tubes does weird things.

KEATPE  most enemies are invisible, but they die when you touch them.

KEATZE  enemies don't die when you jump on them, so by jumping on the 
same one over and over, you get several 1 up's. But shooting them does 
kill them.

UAYIUA  take no damage from touching enemies!

NYTELN  items that were worth 1,000 points, are now worth 1,000,000,000 
points!! (if I'm not mistaken, thats one Billion points.) 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.


YNAOPO  time starts at 150 instead of 400 (plus about 30 seconds of 
invincibility at the start of every life).

LEAOPO  time starts with one extra minute (460 instead of 400).

LXAOPP  time starts at 600 instead of 400 (plus about 10 seconds of 
invincibility at the start of every life).

GVAOPP  time starts at 995 instead of 400 (plus about 20 seconds of 
invincibility at the start of every life).

TSLIIT  most enemies are gone

TSPIIT  all enemies are gone! (Sorry, this code doesn't seem to work on 
the SMB only version.)

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...

VTYNYA  mario has a seizure when he walks (his legs move much faster 
than he's walking).

NEPELA  play as Game Boy mario (everything is black & white).

VGANAA  when mario jumps while running, his little legs start running in 
mid air.

NTPOLE  everything is offset by about 2 inches

NTPOLT  everything is different, plus castle is missing at end so mario 
keeps walking forever.

NTPOPT  almost a solid row of coin blocks and tubes in 1-1.

AXAENT  invisible worlds. See how good your memory is.

NGPOKK  mario starts out swimming in a completely new green underwater 
world.

ZSNENT  mario turns into the invisible man. This code works on both 
versions but does different things.

ASTETE  play at night

SSASSA  invincibility!  Let an enemy touch you and see what happens.

AALLEY  most enemies are frozen!

PIGOAP  swim without water (you're always swimming)

VTLOKK  1-1 enemies are gone or different, especially if you go down the 
tube. (can't go past 1-1).

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!  
Also notice that this code is completely different than any of the 
Galoob jump codes in the book.

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.

VGAOKK  new cloud world (use with PIGOAP)

VGPOKG  new water world

VTPOKK  new underground world

ASAOGG  new maze world (use with PIGOAP and be ready to press jump 
button as soon as game starts).

NGPOKG  start at 1-2

NGZOKK  start on world 3 ??? (use with PIGOAP)

VTPOKG  start on world 5 ???

NTPOKK  start on world 6 ???

OVAAAE  slow-motion, plus other neat stuff

SYLOKG  no enemies, or in different places (use with PIGOAP or AETLTK to 
help get past some levels, like 1-2).

SYLOGK  Mario swims instead of walking in all blue background worlds.

YETLYG  Mario has variable jump heights. Sometimes he jumps high, 
sometimes low.

PETLYG  similar to above code

KTLOKK  different enemies in 1-1 (flying fish will appear if you are 
using the SMB only version, also, you can't get past 1-1).

VGAOGG + ZLAOKK  cool underwater world

TEGOGG  another maze world (stuck in 1-1)

NTLOGK  Mario swims in some worlds (and different enemies).

EAZLIT  Mario can't shoot

VGLOKK  all worlds have different or missing enemies (use with PIGOAP or 
AETLTK to help get past some levels. Also, if you use this code with
        the SMB only version, you can't get past 1-1, but if you use the 
SMB/Duck Hunt version, you can get past 1-1.)

AITOSA  Mario walks past castle at end of 1-1 and keeps on going forever 
(this is the first code that I ever made for SMB. WOW! :-)).

STPONE  all castles are missing, but game still plays normally.

NTPOLS  after the first pipe, mario keeps on going forever (no 
obsticles).

GNATUE  enemies follow you! (Best if you use this code with SSASSA).

UATIUE  invincibility! Mario walks right thru enemies. (this code is 
completely different than my SSASSA invincibility code).

PLAOKK  starts out in new cloud world (or underwater world if you have 
SMB only version), then you drop down to some new underwater worlds.

TTPOZG  1-1 has stuff from other worlds.  Cool.

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.)

PAZULG  Mario can float for a very long time. You have to press and hold 
the jump button for this code to work right.  Only works from a standing 
start. (This is just a simple modification of a Galoob code).

PLZOKG  start at 2-1 ??

STPENT  x-ray vision (bizarre).  Shows where hidden blocks are.

PLZOKK  start at 2-1 ??, then it goes to 1-2.  (use with PIGOAP).

VTLNKA  it rains "200 point" icons

TAAPIG  almost a solid row of blocks in 1-1, and 1-2 (can't get past 1-
2).

PAAPIK  similar to above, except you can get past 1-2

NIYNEE  in 1-1, the enemies have hammers

PLAPKG  start at World 3-1 ??

LSAENT + ZLGOKG  new worlds (hold "Right" on controller #1, and use 
controller #2 to control Mario).

ASAENT + NTPOPI  at the end of a new underwater world, Mario keeps going 
for a LONG time, and while he is walking, you get to see lots of 
graphics from        different parts of the game.

ASAENT + NTPOZT  new underwater world

OLZPKG  new underwater worlds

YSAENV  starts out in underwater world, then goes to 1-1 if you die.

ISAENT  if you press the "A" button, you can position Mario anywhere on 
the screen.  If you don't press the "A" button, the screen won't scroll.

ASAEVT  worlds are different (this code works very differently depending 
on which version of SMB you have.)

ASAENP  all worlds are very weird & different colors

YLAOKK  some new worlds.  You get to swim in most of them.

ILAPKK  start at world 2-1 ? (only goes 2-3 levels)

YLAOKK + ILAPKK  6 or 7 new worlds! (always swimming)

TEYVPA  enemies that are up on blocks don't fall down (and other 
oddities).

TTLEXP  worlds are really strange

(NOTE: This code below works best only on the SMB/Duck Hunt version.

YSYENT  there are different enemies in 1-2, 4-1, etc.

That was a long list, wasn't it? After you try a few of these, you'll 
probably agree that SMB is the greatest game ever for Game Genie hacking 
:)

SMB2
Note: Some of these may not work, because some of Adam Blake's codes 
have different effects or don't work on my version. It is possible there 
is more than one version of the game or the Game Genie.

Note: If you don't notice the effect right away, leave the Sub-Level 
(you start the game there) and you may notice it.

Note: I only used Mario to test these codes, but they should work for 
the other characters as well.

Behavior Codes

EPAPPS- Enemies walk off ledges rather than turn around.
ELKELK- Enemies are invincible. Pidgits become glitches.
ZTEOAK, ETEOAK, STEOAK, TTEOAK, VTEOAK, YTEOAK, NTEOAK- Mario changes

veggies.
ITEOAK- Same as ZTEOAK, except Pidgits are invincible.

and lighter as you proceed through the level.

Yup, that's it. Not much compared to the SMB1 section, eh? Send me some 
codes for this game.

SMB3
Note: These codes may not work on some versions. Some of Adam Blake's 
codes don't work on my game, or have different effects that what he has 
listed, so there may be more than one version of the game or the Game

one.
AOSZZI- Fly into the air after hitting a block, and come down at the end 
of the level.
AOSZZY- Pirahna Plants randomly become invisible. Makes the game a 
little tougher.

TYXXZS- Mario's clothes are black.
AYXXZS- Yellow clothes.
PYXXZS- Light Green clothes.
ZYXXZS- Green clothes.
LYXXZS- Blue clothes.

New Level Codes

ZTZOAS- Unable to move on map. Press A to enter a wierd ice level. 
Another excellent code by Adam Blake!

Freezes/Traps

TYXXZT- When you hit a power up block, the world flips around and you 
are unable to escape (I call it the "Parallel universe"). Give this one 
a try!
TYXXVI- Freezes when you enter a level.
AOSZZT- Game freezes when you enter a level, but the music keeps going.
AOSZZU- Game freezes when you get a mushroom.
AOSZZG- Game freezes when you try to fly.
NEUZUGAE- Glitchy map screen. Cannot move.
YEUZUGAE- Same as above, but better!
AEUZUGAE- Warp Zone. Plays music, but you can't move.
EEUZUGAE- Dark Warp Zone! Music constantly changes! This is my favorite 
code (that I made, anyway).
PEUZUGAE, OEUZUGAE, ZEUZUGAE, XEUZUGAE- All of these take you to a 
"Pattern Table", each with different music playing. Give these a try.

Other Codes

AOSZZK- Sound for "Power Up" different.
AOSZZA- Music on map different, level SFX glitchy temporarily.
AOSZZE- "Enter Level" sound slightly different.
AOSZZX- Sound for getting hit changes.
AOSZZK- Music and sound change when you get a mushroom.

OVPAIE + NNPOKG  all worlds are in the clouds!

ASAENT + LSTETA  very long new underwater world

VTZOZK  all outside worlds are different

YEUXKGAA  start the game as a plant/cloud. With this code, you can go 
past as many levels as you want on the map screen.

ONKXGLIE  start and stay as Invincible Mario. But, you can't go down 
some tubes.

AEUXKGAE  start the game as ??? Then, if you get hit, you turn into 
Tanooki. While you are Tanooki, the whistle is blowing all of the time, 
so you can start flying immediately!

AXUXKGAA  similar to above

UUKXGLIE  start and stay as Little Mario (invincible)

AANZKLLE  no turbo running

EANZKLLA  2 Marios when you press "B"

Again, not nearly as much fun as SMB1, unless you find some seriously 
wacky codes to send me. Don't hesistate to send them in, after all.

This list is FAR from complete! Alter some of the above codes (see the 
Game Genie instruction manual for more details) or create your own new 
codes, and see if you can get some wierd effects, then send them to me 
and I'll add them to the list! Also, let me know if you find some 
effects for the listed codes that I didn't put under the description. I 
can be reached at edmoogle@hotmail.com (subject: chocobo) or 
brunerp@juno.com.
