GG Codes for Double Drgaon 2 - NES

[OldSchoolGamer]

Mission 1 boss appears much earlier
AGGAKN
NOTE: After you beat the first set of enemies, two Mission 1 bosses will come out & apppear glitched. After you beat one of them, they appear like normal. There's no end to them either.

What do you mean when you say there is no end to them. Do you mean you can't advance to the next level? Or do you mean that they keep reappearing?

[BigBossman]

You can't advance past them. When you beat one, another will come out & take his place. They just keep coming. I must have beaten about 10 of them before I gave up. I tried tinkering with this code to try & find other enemies that appear, but have had no luck so far. I'll keep working at it.

[BigBossman]

Regular uppercuts knock enemies way up into the air
YZAAEO
NOTE: This is the uppercut that is normally done at the end of a normal forward attack combo. The enemy will be propelled up off screen & will land a short time later.

Weird music
ITIAGK

More Weird Music
GEZEAL

[BigBossman]

Didn't find anything spectacular this time around. I mostly found sound or music codes. Here they are:

Music missing beats
ZVAAAZ

Red Health Display
EZIZOE

More Strange Music
IPGAGG

Some SFX last longer or loop
LUZATK
NOTE: This applies mostly to punches, kicks, thuds, powerful hits, weapons hitting the ground, the go ahead finger, & even the pause sound.

[BigBossman]

The screen scrolls further to the right
AIIISX
NOTE: This will cause the screen to move further to the right. Most enemies will come out sooner. This may cause some parts of nonscrolling stages to be solid black (Missions 3 & 7).

Enemies fall straight up & down when they are knocked down
GKZZAT
NOTE: They don't fly through the air.

Can't throw pipes once you pick them up
AIIEGK
NOTE: This also alters the sound of jumping, pausing, weapons hitting the ground, & also changes the sound of the go ahead finger.

Removes some beats to the music & adds a tapping noise to parts of it.
YZZAAG

[BigBossman]

Mission 3 helicopter door is always open
KGZLUG
Note: This door won't appear to be open, but everything will start moving toward it. This makes it easy to clear the stage. Once the last enemy goes out the door, you'll still continue being sucked toward it while the end of stage music is playing, but you won't loose any lives. When you pause the game, it will permanently freeze.

[BigBossman]

Advance through the game in seconds
KOLPGS
NOTE: You don't actually play the game. You zip through the stages until you reach the ending of the game. To see the games true ending set the difficulty to Master.

[BigBossman]

1 Hit kill from some enemies
XXGOES
NOTE: You'll notice this after you climb the first ladder of Mission 1.

Can only perform 1 elbow to the back of the head instead of 3
EIPOIS

Can perform an infinite amount of elbows to the back of the head instead of only 3
EIPOYS

Weird enemy movement
KUPUTL
NOTE: Not sure how to explain this one. Usually Williams will come running & doing cartwheels. With this code active, they just walk toward you. Also if you move up or down, the enemies will move up or down before walking toward you. They also move weird on the 2D parts of stages too.

[BigBossman]

Music plays much faster
STAAAG
