Game Genie NES 8-bit codes

Game Genie is a device made for the Nintendo Entertainment System, that alters the addressess in the ROM of the game, the addressess has values that control number of lives, the stage you start in, the state you are in, how high you can jump and everything else of the game, so by altering these values you can get various effects like infinite lives, start on a specific stage (even hidden ones (as you will see...)), jump higher, and various other interesting effects that makes you do stuff that you couldn't before. Game Genie is the wizard of Nintendo.

Here are homebrewn codes made by me and others on the internet, collected here:

(it is not for certain that these codes will work on a emulator or any other than the european version, but try it out, perhaps they will)



Super Mario Bros. 1

OZTLLX - Be little Mario all the time, with fire flower also.
IKEIKE - mushrooms kill you.
PIATYP - Enemies can go through anything, (noclip for enemies).
VGAOPO - Every stage is like a bonus stage, and if you fall down you go to coin room.
YYTIEA - Interesting code, enemies are invincible, kill them over and over again and you get 1ups.
PIGOAP - Swim at any stage.
PINAAO - Move even while pause.
SSASSA - Enemies die like if you had the star.
STAGEO - Enemies won't move.
KPEPNY - Fish jump at first stage.
PAKIST - Climb the flagpole (I found this myself), win when you reach the top.
EAISXN - Go through walls to the left (noclip to the left).
XXTTSP - Fish instead of goombas and koopas (found this myself).
VVLLLV - Fireballs from Flower-Mario stays on you (found this myself).
ENTAGG - 1up when you kill enemies or take mushroom (found this myself).
SPZYYX - The end of the screen won't stop you (found this myself).
ASZXNN - No scrolling.
NAPZXN - Many things happen.
PXKAST - Neat scrolling effect (you can't play the game though).
YSEPAG - Bricks as ground.
GSEPAG - Bricks are replaced by ground at 1-2



Super Mario Bros. 2

AAAPEG - Enemies and objects colour are the same as your character.
AKPOOZ - Wart music from the start.

*KPOOZ - ******** music from start.
ANPOOZ - Star music from start.
AEPOOZ - Silent music from start.

(found the above myself)

KEAPXP - Enemies die as soon as they spot you (found it myself).
KEAPNP - Enemies are invincible (if they don't fight eachother (found it myself)).
KEAPUP - Enemies can fly (the boss too unfortunatly (found it myself)).
SPELAS - Enemies die as soon as they spot you 2 + other effects (found it myself).
POPPPE - Take as many plants you want (found it myself).
KEAPIP - Take as many plants you want 2 + other effects (found it myself)).
GEAPIP - Take a plant and a hole is made underneath it (found it myself).
STEPPY - POW blocks bounce (fun code!).
NSPPLE - Take as many plants you want (not really, they disappear after a while, that won't happen with MY codes, lol).
SXGAOO - Enemies follow you.
PINAAO - After throwing a bottle of door-maker-xtreme all enemies will stop moving, also effect-music.



Super Mario Bros. 3

AIIIIZ - All enemies die if you stomp on them (even those ugly creatures in the pipes), don't get the mushroom, or if you allready have, don't get small (found myself).
ZSIKXV - Star all the time, can enter anything on the map, START leads you to the hidden level (a real hidden level - sort of a test level (found myself)).
OZZXXN - Mario looks at you all the time (found myself).
EEAAAS - The hidden level (game freezes after you made it).
ISZXXU - Night level, you must allways move or the game freezes (found myself).
VEAAAI - Can't walk anywhere, press "A" where you are and you come to the secret level, and when finished only to arrive at the same place and play again (found myself).
SOZVLL - Many songs on the level (found myself).
TAAGEI - Shoot shells for 1ups.
KAAGEI - Shells follow you!
YXKGEE - If you move, the timer goes slower (found myself).
OAOXUN - Some enemies die as soon as they spot you.
YLLLLI - Go through things to the right (except on stage 2 and 5 (found myself)).
OEPZXZ - Points that are visible (100 etc.) will give you 1up.



I hope you enjoy this, and appreciate how much time has been spent on finding these codes (time that has been surprisingly fun).

GALOOB!

I have a ton of those old Game Genie booklets that had codes for the NES and SNES games.
Let me know if you need codes!
Of course, you're on the internet, so such information should be readily available to you by other outlets.

Yes, I allready have the original codes in the book, what I'm looking for is homebrewn codes, like the ones I posted so if you have any of them I would be very interested.

I loved using Game Genie for Street Fighter II. Aerial moves, funny sayings, and other stuff. Fun times.
