NES (EUR) Game Genie codes by Cyperium

[Cyperium]

Super Mario Bros. 3:
AASLAXZG - Can scroll up even when powermeter isn't full. Doesn't enable scroll on non-scrolling levels though.
ZGELIZYE - Can scroll up even when powermeter isn't full. Doesn't enable scroll on non-scrolling levels though (alternate).
YGELZXVT - Can scroll up even when powermeter isn't full. Also enables scrolling on non-scrolling levels (the ship will be static and not move up and down, instead bullets and stuff will follow scrolling up/down making them a bit harder to dodge). Some later levels in the game might not be possible to pass with this code on, have tested most of World 1.
AZKPOAAT - Enables scrolling on non-scrolling levels, non-scrolling levels will behave normally when you don't have full power-meter (solves the problems with YGELZXVT). Levels where you don't need full power-meter to scroll behaves normally.

Zelda 2:
AIUOGGEY + EOXOPLEY - Walk through walls (when in side-scrolling mode).
AASOPSAA - Jump through roof.
OEUSIPLE - Moon jump (jump until you release A, don't jump too far off screen or you wrap around and become invisible).
AVNTPXSZ - Invincible against enemies.
VZVTPGAX - Invincible against projectiles (you can still be pushed back a little bit).
AEUSVPAP - Walk through locked doors.
SXEPOOGK - Scrolling doesn't stop (unfortunately anything you see beyond the borders are illusive and you'll fall through the ground).

Lolo 1:
AEUZVYNY - Treasure chest is always opened.

[Cyperium]

Castlevania 1:
SXEOLKGK - Wrap around to the top if you jump into pit (not if you just walk into the pit, or if you get pushed in).
SZNPLVGK - Wrap around to the top if you get pushed into pit (not if you just walk into the pit, or if you jump in).

YUVXAPAN + SXNZAOSE - Never die, instead wrap to the top, game can't continue if you run out of energy or time (allows you to wrap to the top if you walk/get pushed/ or jump into a pit).

NPXPEZLK - Don't die when time runs out.

Zelda 2: Walk through walls (when in side-scrolling mode).

I was having a fuck of a time hacking this code. The best I could do was make Link and enemies walk through walls, but they fell through the floor too.
Fantastic codes! I'm adding to your reputation for these wonderful codes!

[Cyperium]

Thanks! I think it would be pretty straight forward to convert the codes to the US version as well (these are for European version). In fact, I'm thinking of making a post with US converted codes for various games for some of the more useful codes

I just hope I won't get into the same trouble of falling through the ground when converting Zelda 2 walkthrough walls to US (most of the time there aren't that much differences between versions so I might have found a code that works on both, let's hope that I'm correct).


Ok, so the US version of the codes for Zelda 2 walkthrough walls are AIXOYGEY + EOOOGLEY.
US version of Zelda 2 jump through roof is AAKOGSAA.

[Cyperium]

Kirby's Adventure:
SXUXNAAX - Walk through walls, you need some speed and you will also fall through the floor so be prepared to fly.
GEOEATPA - Run much faster.

[Cyperium]

Zelda 2 - The Adventure of Link:
ATEVILSA - Don't get hit by enemies (alternate).
ATKTIGAZ - Don't get hit by projectiles (they move right through you).
ATNTYLEI - Don't get hindered by enemies striking your shield.

The boss is a special case, has to use a different routine or something cause you still get pushed by him when he strikes at you no matter what code you use, can make you fly all the way to the roof if you have a invincibility code on (and if there is no roof you go over the top of the screen and become invisible when you wrap around).


Kid Icarus (Europe) (Rev A):
SZEGVKGK - Wrap to the top if you fall down a pit.
AAEKXGAP + AANSPXGA - Wrap to the bottom if you jump over the screen.
SIUSLZST - Jump higher.
SGUSLZST - Jump very high.
AEEITXAP - Jump through roof, not in dungeons though.
AEEIZXYA - Jump through roof in dungeons.
OZUVKISX - Infinite energy.
SZOVAAAX - Walk/jump on air, press down to go down.
SEUESIIT - Buy things for free. (same as the Europe, USA code)

Kid Icarus (Europe, USA):
ASKKKLEP - Wrap to the top if you fall down a pit.
SEUESIIT - Buy things for free. (same as the Europe code)

I saw a walk through walls code in the database, but it doesn't actually make you walk through walls, instead it is a jump through roof code, so I might change the description later. I've tried to find a walk through walls code but the ones I've found so far has all kind of side-effects.

[Cyperium]

Ufouria (E):
ZASYTGGA - Jump higher
AEUVSLLA - Walk Through Walls (some enemies and bosses might get stuck)

[Cyperium]

Super Mario Bros. 3 (E):
AEEXXKZA - Fly from standing start.
SZNLZISA - Walk on air until you jump (doesn't work on stages with slopes).
ATKLPIEP - Jump/Fly through roof (doesn't work on stages with slopes and not with blocks that you can act upon).

SZULZISA + EUOZIYEI + AVNULGEZ - Walk cleanly through blocks (doesn't work on stages with slopes), the first code is based on YLLLLI, the second code stops you from moving to the right while inside a block and the third code stops you from moving left/right while on the edge of a block. Be careful not to jump while inside a solid structure, you will fall through the structure until there is a gap (if there is no gap you will fall off screen and die).

AESLYIIZ - Take ice from nothing, breaking scenery.

[Cyperium]

Mega Man 3 (E):
SPKESEPZ - Scrolling doesn't stop (both directions), in rooms that have no scrolling the scrolling won't start. You can't scroll up/down when climbing ladders (if you try to climb down a ladder you will fall off screen and die). For this code to be useful you usually need to combine this code with a walk through walls code.

[Cyperium]

Super Mario Bros. 3 (E):
ASKSPZEY + APKSTLAZ - Move freely on the map (except through unfinished stages). First code enables you to go anywhere on the map except unfinished stages, second code makes you go one tile at a time. This code exists for the US version (made by DahrkDaiz), but didn't work on the European version.


SXNKVSOS - Go past unfinished stages (this is a better version of a previous code I made which had much the same effect, will update the code in the database as I found that that code didn't work well on the second world).

EUOZIYEI + EUNLTGEI - Walk cleanly through wall (better version of a previous code I made, with this code you don't risk falling down and it only requires two codes).


Super Mario Bros. 2 (E):
OXEPXPEN - Enemies die on sight, a variation of BeyondTheStatic's code found independently and converted into 8-letter code from KEAPXP.

[Cyperium]

Super Mario Bros. 2 (E):
SZSYPXGK + TPSYAZXE - If you fall down a pit you wrap to the top.
PENVLPAA + SXNVYOSE - Area modifier (?ENVLPAA), takes you to different areas on the level. Valid values for ? can be A,P,Z,L,G,I, where I takes you to the boss. Only tested on 1-1.

[Cyperium]

Legend of Zelda (E):
AAEAKVXY - You can always attack (if you have no sword the sword will be invisible)
ASOUUAEY - There's a heart in every screen (except in the dungeons), the heart is placed on
the same coordinates as the heart where you need the bridge to cross in order to take it.

[Cyperium]

Castlevania (E):
NNEPLKYL + SEEPGKAU + KEEPIKOT + IEEPTGET + SXEOLKGK - control movement in mid-air when you jump.

He doesn't face the direction you want, only moves in the direction.

As a positive side-effect SXEOLKGK enables you to jump into pits without dying (it is needed for the code as otherwise you would die randomly when jumping). The codes work well with nolberto82's jump in mid-air codes (you can now jump over the screen without dying). Walking into pits or taking damage into pits still causes you to die.

[Cyperium]

Metroid (E):
AAOSYTAL - Shooting breaks any block.
AENIAIZA - Explosion animation when hitting a object.
AIOIZTEL - Shoot through walls.
AIOIZTEL + GAOILTAO + AZXIPVGG + IGOIPTEX - Shooting slices through blocks and destroys them.

Shooting breaks any block and shoot through walls can't be combined (the shot will be instantly destroyed), if that effect is wanted you should use the last code which slices through blocks.
