Bigbossman's NES GG Codes: Various Games

[BigBossman]

P.O.W.

Fewer Enemies
AVGEAA
NOTE: This may look like the game crashes as soon as you start, but it won't. The screen will start white & you won't see the SNK logo pop up. Then the screen will turn black with only the arrow visible. Press start & the game will start like normal. The only time you'll see enemies are when you go into huts, APCs, & other places & also the bosses. The enemies will all look like jumbled versions of your character. For example, the enemies with knives will be holding a knife. When they go to stab you, they appear to be holding the machine gun. The helicopter will appear somewhat glitched & the 2nd stage enemy boss also looks like you as well. This code will also disable the music.

Ninja Gaiden 2

Most green enemies have an orange tint
XTAKEN

Most walking enemies are lower than normal
ELGPPZ
NOTE: Most of the walking enemies will be positioned lower. In most cases, you have to duck in order to kill them with your sword.

Most walking enemies fall through the floor
EAGPPX
NOTE: Most of the walking enemies will fall through the floor & fall off the screen. Some of the enemies that are higher up will usually fall to alower position & not off the screen.

Snow falls on the 1st section of Stage 1
OSIAXU
NOTE: This is the very similar to the snowfall on Stage 2-2. However, it only blows straight down, it doesn't keep shifting. Once you get past the first section (where you climb down), the snow doesn't fall.

[BigBossman]

Spy Hunter

The road doesn't split / Road is much wider
AIAIAI
NOTE: There will be sand patches in the middle of the road every so often. Also the road changes frequently. Generally it will shift from to the boat stage & then back to the car stage. Helicopters will appear also when you are in the boat.

[BigBossman]

Ninja Gaiden 2

Most walking enemies move slower
ELPOZX
NOTE: This only affects enemies that move from right to left. This will affect most of the enemies that walk, the 1st stage boss, rollers, bats, & even enemies that run at you.

Most walking enemies move much faster
NYPOPX
NOTE: This only affects enemies that move from right to left. This will affect most of the enemies that walk, the 1st stage boss, rollers, bats, & even enemies that run at you. This makes the game incredibly difficult.

Invincibility weapon doesn't work
AXTTIG
NOTE: The invincibility sub-weapon, will not make you invincible. You'll hear the sound effect, but no flames will surround you. It also takes points away for using it.

Most sub-weapons act as invincibility
PIGPOG
NOTE: Fire wheel & boomerang star will cause you to be invincible for a short period of time, but won't take as many points like with the actual invincibility sub-weapon. The dragon ball sub-weapon moves straight down instead of a downward angle.

[BigBossman]

Ninja Gaiden

Can't collect the ninja star - deletes current sub-weapon
UKISXU
NOTE: Collecting the ninja star will cause you to have nothing in your sub-weapon box.

Can't collect the boomerang star - deletes current sub-weapon
UKISKU
NOTE: Collecting the boomerang star will cause you to have nothing in your sub-weapon box.

Can't collect the firewheel

[BigBossman]

Castlevania 3

Small hearts drift further to the right
EGLZPA

Start with Sypha (6 digit code)
EGLPPA

Find alternate stair cases
ZVPPOU
NOTE: This only works when you are on a set of stairs going up. Have Trevor look in the opposite direction & push up on the control pad. This will cause him to start climbing an invisible set of stairs. This can help you to bypass certain areas. You must have a ledge that is above you. It's possible to get stuck in a wall if you're not careful.

[Unicode]

Castlevania 3

(...)

Start with Sypha (6 digit code)
EGLPPA

NOTE: Music will only play when you're fighting the bosses.

[BigBossman]

Castlevania

Cross powerup is always in effect
EOLYXZ
NOTE: Upon pickup. Enemies will die as they enter the screen. This doesn't work on bosses.

Items from candles look strange
KKZVEU

[BigBossman]

Ninja Gaiden 2

All stages scroll similar to Stage 2-1
KPYSIE
NOTE: This makes every stage act as if its the train stage on Stage 2-1. The bottom part of the screen scrolls really fast, the middle top portion scrolls fairly quick, & the very top portion scrolls somewhat slowly. This can make the game confusing depending on the stage you're on.

Fewer enemies & orbs
SALKTY

Random enemy & orb placement
SILKYN
NOTE: Most of the enemies & orbs will appear at the start of every stage. As you get toward the end of the stage they won't appear. Secondly, on Stage 2-2 some portions, you won't be able to see the wind direction, but the wind will still blow.

[BigBossman]

Adventure Island 3

Auto Hop
SGPZXZ
NOTE: Makes the game more difficult. It causes you to do small hops constantly. You have to time your button presses properly in order to jump like normal.

-----------------------------------------------------------------

Super Pitfall

Invincible to Enemies
ZPGEPX
NOTE: Not to ground spikes or lava.

Multi colored stages
YZPEPZ

Walk slower than normal
PZTVNZ
NOTE: You'll walk at the exact same speed as the spider. However, this will not affect your jump.

---------------------------------------------------------------------------

Batman
I don't know what that enemy is called so I will refer to it as the rolling thing with two spikes.

Rolling thing with 2 spikes always moves fast
PYPPPP
NOTE: Even if you aren't on the same level as it.

Rolling thing with 2 spikes moves slower when you're on the same level & faster when you aren't
PPPPPP

APTXXE

Ninja Weapons are disabled (not the basic sword)
APTOXE

[BigBossman]

I should have some more 6 digit codes to contribute to this section soon. I'll post them a little bit later on. Most of them are for Double Dragon 2, but I have been trying to work with other games too to stumble across something.

[BigBossman]

Double Dragon 2

Less Gravity
YYLXPA
NOTE: Makes it to where you & enemies jump higher & further, but also makes it to where weapons bounce a little bit higher when they fall.

Weapons never hit the ground
PKZPXZ

Masked Man never dies by beating him up
KSTEXU
NOTE: In order to kill him, you have to knock him off the edge. His mask will drop to the ground, then he'll suddenly start attacking again.

Weird Enemies
TIGOLA
NOTE: Modifies one of the enemies that don't come out of a door into Billy or Jimmy Lee. Also Rowper's attire appear blue most of the time & Linda's skin tone is blue. On occasion Rowper will do cartwheels similar to Williams. The game will lock up when you use a knife or grenade.

Ninja Gaiden 2

Foreground & platforms flash
