Personal list of NES Game Genie codes
« on: April 15, 2017, 03:33:00 am »
@DJ Omnimaga wanted me to make this, so I am :P

I have an Everdrive N8 and an NES at home, and I love to play on it often. One thing that's sometimes fun to do, besides playing the games, is making up useful, funny, or just interesting Game Genie codes. I will post new codes I make for new games as I create them.

Also, yes, every code here is of my own creation. Almost.

Big Bird's Hide & Speak
ASETPAEYYou will select the right person, no matter who you select (game might softlock)
ENKLTTEIEveryone, no matter if they're the right person, nods their head after you choose them
ESETPAEYYou will select the right person if you select anyone that's not him
PEUTIAGAYou only need to select 1 person correctly to win the round
YLXVUTYTBig Bird NEVER speaks
ZZEUTZTZAs soon as the characters enter, they are all Ernie; game softlocks after round

Blurred Lines 2048 (yes, that's a thing)
AAATATOnly 4 tiles spawn
EIIVTGMute the DPCM channel (no "Hey hey hey"s or "Everybody get up"s or similar will play)
ZEYVAIAlternate code to AAATAT

Kirby's Adventure
AAAPKTInfinite energy

Mario Bros
ENTSZZEarthquake when POW block is hit

Pac-Man
AYATLAOnly need 1 dot to win

Sesame Street Countdown
ASPLULEvery number you choose within the level, no matter what, is counted as correct
AYIZELThe Count says that every number is correct, but it might not be
POPZAANo matter what number you choose, The Count will always say a glitch number called "ah ah ah"

Summer Carnival '92 - Recca
AXUSYKGG+KSKIPGUIActivates an interesting (unused) intro: the SEGA logo and jingle appear, then explode, and then the Nintendo logo drops down and plays the Game Boy startup sound effect

Super Mario Bros
AATLOGPowerups don't come out of blocks
AILALL2-player mode is disabled
AIPVEZEach Toad looks like Peach
AITELGPress B at a Toad to go back to the title screen and unlock "hard mode", effectively beating the game
ANYAAZA rather...umm...interesting way of starting on World 2
ANNEPIEYMario has the palette of Luigi
ASALPA+TGYOPOWalk around in the intro of 1-2 (can't escape)
AYOETGEY+YZVAEEZY+YZVASALIMario is always referred to as Luigi in-game
AYPVEZYou rescue Toad at the end of the game
AYTELGYou continue on to 9-1 at the end of the game (seems to break Coin Heaven; game crashes at World A-1 if you fall down)
AYZEPGPeach will tell you the princess is in another castle at the end of the game
GTAOZPThe Starman music plays instead of the regular music
GTLPXZEvery brick is loaded as a cloud
GVAPZGThe ground is rendered as clouds
GVPLAPYou don't die by falling down pits, but you come down in a sublevel (for example, falling down the pits in 1-1 put you in the underground section)
GVPOZGOnly one row of the ground is rendered
LYZSVAInstead of becoming Fire Mario when collecting a Fire Flower, the sky changes to night
NNILXIEvery mushroom/flower is replaced with a weird Koopa-shell powerup that acts like a Starman
OOIINGBecome Starman-invincible whenever you hit a block (WARNING: can crash emulators)
PZPPANEvery screen in the game scrolls (even the intro to undergroud/underwater stages, and the Warp Zones)
SUYLUYAnything that falls down the bottom will appear on the top, and vice versa (you can't escape Coin Heaven; buggy behavior with lifts)
TXZYGVThe death noise sounds like a pulse fading out...I dunno how to describe the sound
VTAETUOnce you beat the game and can press B to select a world, you may select any world from 1 to 255 (world numbers appear as graphical garbage, and levels are loaded as garbage data; some may crash)
VTLAPEImmediately start in an inescapable water world (not the Minus World), but return to the title screen as normal once you die
XTLGGKLakitu's Spiny Eggs do not fall straight down; they veer to the sides based on your position, speed, and random chance (not tested completely)
XYTEIXPress B at the title screen to change the world you start in
  • Combine ANNEPIEY, AYOETGEY, YZVAEEZY, and YZVASALI for full gameplay as Luigi, even in 1 player mode! (Requires 2 chained GG devices, or some method/apparatus for entering more than 3 codes.)
  • Combine GTAOZP, GTLPXZ, GVAPZG, GVPLAP, and GVPOZG for a full Coin-Heaven-like experience! (For normal GG devices with only 3 codes, the middle 3 suffice.)
  • Combine VTAETU and XYTEIX to access any world from 1 to 255 right from when you start the game!

Super Mario Bros 3
AATEVTPause is disabled
ALUZZIYZFire Mario now looks more like he did in SMB1
AOZULTImmediately get forced into an unused level (possibly a rejected World 6 level)
EIGXLTIf you duck on any platform for long enough, you will fall through to the background
EYEZEZEITurn into Fire Mario when collecting a Fire Flower while small (instead of turning into Super Mario)
EYUZXGEITurn into Raccoon Mario when collecting a Super Leaf while small (instead of turning into Super Mario)
LPOGVPYXPress Select to toggle invincibility
GGUXSKXV+KZUXNKXV+OGUXVKXVActivates Debug Mode on the menu if holding A+B on controller 2
NNXXKGAEAlways run as if your P-Meter was full
PAIUUTYou fall through to the background on white blocks instantly
ZPXXTSZXLuigi is usually a slightly lighter green in-game than on the map screen; this code makes the color consistent

Tetris (Nintendo)
AYIAEPPieces go down faster when you hold DOWN
ENTONAThe demo is desynced; you get the same pieces every time you play
EYTZAGPress START at the title screen to immediately skip the copyright notice
PALEGZShorter wait at the copyright notice (not too noticeable, though, to be honest)
ZALAAPPartly-functional 2 player mode!
  • Combine EYTZAG and PALEGZ to skip the copyright notice altogether!

Thanks for those codes. I haven't gotten any time to try them as I got sidetracked by many other things, online and offline. I'll take a further look later, though. I'm particularly interested by the SMB/SMB3/Tetris ones. Also wtf about the 2-player Tetris mode? Do you mean the game includes an unfinished one?

Yes, Nintendo's Tetris for NES originally was going to include a 2-player mode. It got cut, but most of the code was left in the game, and is functional (but it crashes if anyone tops out). That code enables it. It's most comparable to Battle Mode in later Tetris games, with each player even sending garbage lines to the other player upon clearing lines. It's a shame that it was cut, because it's actually a fun mode!

Funnily enough, there is another code in the official Game Genie manual for Tetris NES giving a 2 player mode (ENEALYNN), but it was that one player controlled the direction the piece moved, and one controlled the orientation.

I decided to put my hacking skills to the test, and fix what I've always wanted to fix within Super Mario Bros: making it so Small Mario powers up to Fire Mario when collecting a Fire Flower (because, oddly enough, he doesn't :-\ ). This took 12 Game Genie codes, though, so instead of putting it in the Game Genie list, I'm attaching it here as an IPS patch.

Patch it to an original Super Mario Bros ROM with a utility such as Lunar IPS. This will fix the issue of powerups not powering you up enough.

Also, @p2, neither of those codes are valid. Yet, oddly, enough, GGENIE is. :P

Oh, OK then.

And, as it turns out, it's easier to "fix" the powerups in Super Mario Bros 3 (where the same "Small Mario won't power up to the actual powerup" quirk exists for the Super Leaf and the Fire Flower). There are unused flags to see if those powerups are coming out of Big ? Blocks (unused, as in, there are none of those powerups that come out of Big ? Blocks), and if a powerup has come out of one, it powers Mario up to that immediately, regardless of powerup status. "Fixing" that game's powerups, then, comes down to two codes. It's amazing how much unused stuff is in that game.

above my level, but doesn't ths call for a second patch, enabeling most of that unused code to give the game a new touch? ;)

A lot of patches to unlock hidden or unused features in SMB3 already exist. Here are some examples.

  • The hidden debug mode can be accessed with the Game Genie code KKKZSPIU, or you can activate it the "intended" way with GGUXSKXV+KZUXNKXV+OGUXVKXV by holding A+B on the title screen with Player 2. (I say "intended" because there exists a check within the code to see if Player 2 is holding A+B at the title screen, and the area of the code that executes when the check is successful is NOP'ed out...but there is just enough space there to enable the debug mode.) A patch to accomplish the same, with a hacked-in menu to show the effects of the debug mode better, is downloadable here.
  • There is an unused functionality coded in the game that would toggle Mario being invincible whenever the player presses Select. (A popular guess seems to be that this is a remnant of the debug mode, but I doubt it, since Select changes powerup status in debug mode.) The code is still there and fully functional,
     but the game unconditionally jumps past it. The Game Genie code LPOGVPYX will enable this functionality.
  • There are 15 unused levels still in the game's code that seem to be early versions of final levels, or levels made for testing. In three of these levels, there are some new enemy types, the Green Parabeetle and the Gold Cheep Cheep. One of the levels, a World 6-like ice level, can be accessed with the Game Genie code AOZULT (which simply forces immediate entry in the level tile you're currently standing on), because the START tile contains a pointer to this level. An IPS patch that allows access to all of these levels through a hacked overworld map is downloadable right here.
  • There are MANY bonus games that went unused, but remnants of their code still exist within the game. A good write-up on what exactly these are and what they're supposed to do (and what they do instead) is available at The Cutting Room Floor, and a patch to access these bonus games is downloadable right here (apply to the Japanese ROM).

I remember some of the unused worlds from that hacked world map. Aren't some super glitchy and impossible to finish, though?

Yes, some are incomplete or don't end properly. They are all playable, though.
