Darkwing Duck (USA):

UGNGVUSK
UAVGEUTE
XVOGXLAV - Jump in mid-air, when jumping from ground, not when hanging or being hit by enemy. Thanks to Abystus for RAM address!

SZKNAZAX
SXXYLZAX - Walk Through Walls.

AENYEPTA
SEKSIZSZ
SXXGNLAX
SXSNNPAX - Invincible (against both enemies and spikes). You will only ever loose one piece of heart. You will blink when hit and there will be a hit sound, but your movement aren't affected (which is the last three codes). Thanks to VisitntX for RAM address!

AAVEVXAT
AAVESXNZ - No sound when hit.

XVNPOAAV
XVNAPAAV - Doesn't blink when hit.

EENYXPXA - Infinite health (you need to have full health).

AENYEPTA - Infinite health (you don't need to have full health). You will only loose the first piece of the heart when being hit.

SANAZASE
AZNALEGY
IANAGEOZ - Wrap to the top if you fall down a bottomless pit. Screen transitions still work as they should.

PONSSSPA - Auto complete stages. Uses RAM 0050:11 to complete the stage.

AEEAZEIA
ASEETAAP
ASKUIGEY - Bullets doesn't bounce off enemy defense. Some enemies die directly, some enemies just absorb the bullets when their defense is up. Either way the difficulty is decreased as you don't need to wait for the bouncing bullet to leave the screen.

Little Nemo - The Dream Master (USA):

SXKUUAAX
SXXUOAAX
SXVUUAAX
SXUUOPAX
SXSUUPAX
SXNUUPAX
SXNUKZAX
SZNLOLAX
SXEUKLAX - Walk Through Walls (replaces the one I made which is in the database), earlier walk through walls code is in this thread but it is flawed in many ways.

[Cyperium]

Batman - The Video Game (USA):

SZVOOLAX
AAOONLIT - Walk through walls while on the ground.

SZVOOLAX
SXUPOLAX
SXEOULAX
SZKOVLAX - Walk through walls (can be tricky to walljump as you have to time the walljump pretty much perfectly before you clip through the wall).

AEEPTUZA
SXEPALAX - Jump through roof.

AEVPNOIP - Collect enemies, bosses and bullets as hearts. If you collect a boss as a heart the level won't be completed.

IKSPKZIL
ELEOELAI
APXPAGAL
AAEPNLZA - Invincible against background hazards.

ASVTNLEL - Invulnerable to Jokers weapon.

[Cyperium]

DuckTales (USA):

AAUVSUPA
SZETVLAX
SZNVVUOO
AASEXKZL
AIEEGAEY
AAEVNLPA - Invincible (moves a bit up when hit, aborts jump, not added to database because of the shortcomings (coupled with the amount of codes)).

SGXIYLZO
ASEIGZEI
OXENGGSX
OZKIPLSX
SZEIXGSA
SZXTSKOX - Invincible (either destroys/rides or are unaffected by enemies and other things that can hurt you). Unlike the invincibility codes in the database this doesn't require you to toggle on/off codes (in order to pogostick bosses or continue after you've defeated them).

OSOVGLAE - Get suspended in air when hit, you don't loose any health, you can then jump away. Doesn't work on plants and in the following scenario; when a enemy is in your hitbox and you jump while being near the ground, then you may get damaged or even pushed through the ground. The code below doesn't have this problem, which is why I'm adding that to the database instead.

XEOVGLAA - Get "swallowed" when hit, you don't loose any health, you can then jump away. Doesn't work on plants, but works on anything else. Use with OXENGGSX and you are invincible against all obstacles and enemies.

OXENGGSX - Invincible against plants.

LEKSLOAE - Instead of falling into bottomless pit, you get suspended in air and can jump away. Be sure that you can reach the ledge or you will have to wait in the pit until the time runs out (in the Amazons there's a pit where you won't be able to make it out with a jump), transitions still work, this code only applies to scenarios where you would otherwise die.


RAM:

[COLOR=white]0039[/COLOR] controls position in the jump table to jump to, used for different effects. The jump takes place at ROM address [COLOR=white]07:E393[/COLOR].

[COLOR=white]0039:00[/COLOR] - Normal play.
[COLOR=white]0039:01[/COLOR] - Related to falling/jumping. Becomes 00 when landing.
[COLOR=white]0039:02[/COLOR] - Bounce on the ground with pogostick.
[COLOR=white]0039:04[/COLOR] - Use pogostick as club.
[COLOR=white]0039:05[/COLOR] - Get swallowed by plant.
[COLOR=white]0039:06[/COLOR] - Get hit by enemy/spike.
[COLOR=white]0039:08[/COLOR] - Fall down bottomless pit.
[COLOR=white]0039:0D[/COLOR] - Lost life.

Sometimes setting the same value can have different effects in different scenarios since the value is set in different routines which sets other addresses as well. But generally these values apply.

I tried to find a "jump through roof" code but it was too hard this time around, maybe later.

[Cyperium]

Abadox (USA):

AAOGSTYT
ASVKUIEI
AAEKUVZP
AIUGUTEI
IAUGKVAG
LZXGKVZU - Enable stage select/invulnerability, etc. (request), you still have to type in the code for the level you want (or be at level 1 if you just press start).

• Start - Stage 1
• Up, Start - Stage 2
• Up, A, Start - Stage 2 (midway point)
• Left, Start - Stage 3
• Left, A, Start - Stage 3 (midway point)
• Down, Start - Stage 4

[Cyperium]

Castlevania (USA):

APVOXNAU - Walk Through Walls (same code as the european one I made).

AVOPUEOZ - Scrolling doesn't stop. Gates doesn't work as they only trigger when scrolling has stopped. Use with Walk Through Walls code to pass through them. Scenery doesn't always match as stages doesn't advance. This code is the same as the european one I made.





Metroid (USA):

APEAXVAU - Always pass password check.

AAUGSOYA - Enable NARPAS SWORD password.

Interesting sidenote: The address that the Game Over flag is set (0300:08) is at DEAD, can't be a coincidence.

[Cyperium]

DuckTales 2 (USA):

ESKTNPSZ
EIXTXZSZ - Walk through walls. (Some areas are not passable as you can't use the cane against any wall).

APOTOGZK
SZEVVGVA - Walk on pits, sometimes you may fall through (if you do you'll just wrap to the top of the screen). Avoid sinking too deep into quicksand, you will get stuck unless you use the walk through walls code and the jump through roof code.

AEOVELLA - Jump through roof.

SXXTVLVG - Moon jump.

[COLOR=white]009F[/COLOR] serves the same purpose that 0039 did for DuckTales, in other words; it is the state Uncle Scrooge is in.

[COLOR=white]02[/COLOR] - Stand.
[COLOR=white]04[/COLOR] - Walk.

[COLOR=white]14[/COLOR] - Jump.
[COLOR=white]16[/COLOR] - Pogojump with cane.
[COLOR=white]17[/COLOR] - Get hit (don't know where this is used, usually 46 is the value for getting hit, probably a late addition as it is between two even numbers).
[COLOR=white]18[/COLOR] - Fall.
[COLOR=white]1A[/COLOR] - Screen transition down when falling (becomes [COLOR=white]1C[/COLOR] which seems to stabilise the screen).
[COLOR=white]1E[/COLOR] - Climb.
[COLOR=white]20[/COLOR] - Screen transition up when climbing.
[COLOR=white]22[/COLOR] - Screen transition down when climbing.
[COLOR=white]24[/COLOR] - Hang with cane on hook.
[COLOR=white]40[/COLOR] - Turn into frog (wrong graphics if you do this manually).
[COLOR=white]42[/COLOR] - Fall into endless pit (becomes 44).
[COLOR=white]46[/COLOR] - Get hit (this is normally the value that gets set when getting hit).
[COLOR=white]4A[/COLOR] - Get swallowed by plant.

[COLOR=white]FF[/COLOR] - Unknown use. Something to do with text, but isn't used in the usual text scripts that I can find. If you set the value manually text is displayed. Could be a glitch value.

Further investigation needed to see if there is a function to values [COLOR=white]26[/COLOR], [COLOR=white]44[/COLOR] and [COLOR=white]48[/COLOR], especially [COLOR=white]44[/COLOR] and [COLOR=white]48[/COLOR] as they break the pattern. Also to see where [COLOR=white]17[/COLOR] is used as it also breaks the pattern.

[Cyperium]

Castlevania 3 (USA):

TEEOZAZA
ZUEOGETL - Start on world 4-1 (other worlds possible by changing the first and last letters of TEEOZAZA to APZLGITY and A to E for more worlds.

[Cyperium]

Castlevania 2 (USA):

AVUAPEOZ - Wrap to top if you fall into water (splash sound), don't drop straight down as you might get caught in a endless loop of wrapping around.

SXXAPPAX - Wrap to top if you fall into water (no splash sound), don't drop straight down as you might get caught in a endless loop of wrapping around.

OZVEAPSX - Can get hit but cannot die. Causes incorrect placement of enemies and other non-playable characters (including duplication).

The text shows the wrong room description though, don't know yet where that is set. Move away from the room and the text will be correct.

RAM address 0514 is the room you are in, 0515 is the image that should be displayed and is set automatically when moving from one room to another, will also change when you change the room in any way (like opening doors).

RAM address 0500 is the current room number. The text displayed when you enter these rooms won't be correct until you leave the room and come back. I have yet to find the address that controls the text.
