"Lumberjack" for AoK.

"LAPMYLOVEPUMP" from Carmaggedon, though I don't recall what it does. I think it turns on the cheat codes.

Up, Down, Left, Right, A, B, B, A, Down, Right, Right, B, A, Start.

Power up fire and power up dunks, from NBA Jam TE (SNES).

Two always come to my mind:

A, B, B, A, C, A, B: Shadowrun's "debug mode" code (Genesis)
A, B, A, C, A, B, B: Mortal Kombat's blood code

The reason these always come up in my head is because I spent sooo much time trying to distinguish each one for their respective games. Shadowrun and Mortal Kombat are two of the early games I purchased for my Genesis system, and I played both all the time. I finally came up with the following to distinguish 'em:
"They're both pronounced "Abacab." Shadowrun has really crappy music (this is when I think of that looping track whenever you go into the bar in the Redmond Barrens and that voice keeps saying something like "Shuttenlouf!" or "Shut yo' mouth!" or something like that), so I relate Shadowrun (remember, crappy music), with ABBA. ABBA has two B's, so Shadowrun has the code that starts off with the sequential B's. Then I think Mortal Kombat's code is the "blood code," and "blood" only has one B, so that code must be the one that starts with only one B."

Yeah I know it's kinda a long and drawn-out relation, but to this day, it NEVER fails! (Yes, I still play Shadowrun on my Sega Nomad).

Oh yeah: The GTA codes get an honerable mention, since I've gone half a year without playing any GTA game and when I started back up again, I still remembered the codes. Here are the ones I remember:
R1, R2, L1, R2, Left, Up, Right, Down, Left, Up, Right, Down - Weapons code (first set of weapons).
R1, R1, Circle, R2, Up, Down, Up, Down, Up, Down - This gets the cops off of your ass.
R1, R2, L1, X, Left, Up, Right, Down, Left, Up, Right, Down - In Vice City, this only replenishes your armor. In San Andreas, this gives you full armor, health, and $25,000.
R1, R2, L1, Circle, Left, Up, Right, Down, Left, Up, Right, Down - In Vice City, it restores your health. This code was abandoned in San Andreas.

Well, the Konami code was the first thing that popped into my mind, followed by IDSPISPOPD... followed by IDDQD and IDKFA.

For bonus points - the acronym in IDS... stands for "Smashing Pumpkins into small piles of putrid debris."

god has to be the first one I really remember using on the pc.

The contra code for me too. Also suckmyrocket from gta1, i think it was all weapons full ammo.

"Porntipsguzzardo"

The $500,000 money cheat for Sim City 2000 (mac only)

First cheat code I ever used.

Lol I love that there is an arguement in this thread as to if the Konami code validly contains [Select] as one of its buttons :)

R1,R2,L1,R2,L,D,R,U,L,D,R,U

Grand Theft Auto....I have typed this in about 10,000 times

up,up,down,down,left,right,a,b,a
mortal kombat 2, ithink

The Konami code man. I even have the T-shirt.

The only cheat code that springs to mind for me is the blood code for the original Mortal Kombat for Genesis. And you all know it already. Up, up, down, down, left, right, left, right, B, A, B, A, Start.

"god" and "noclip"

iddqd and idnoclip, whosyourdaddy, makeitso

We may all know it, but obviously you don't. ;) It's A, B, A, C, A, B, B
You recited the ever-popular Konami code. Listen to The Ataris; they'll tell ya.

i totally agree, it has to be the Contra codes.

That would be the same for me.

IDSPISPOPD (Doom) or GABBAGABBAHEY (Descent)

IDDQD was what popped into my head when I saw the title, but I think the code I used most was +shootall in Total Annihilation, which isn't really a cheat code; it just sets your bots to attack every enemy structure rather than just the turrets and factories.

Black Sheep Wall

First thing that came to mind for me.

Star Craft - Removes Fog of War and uncovers the entire map I think.

operation cwal

lumberjack

robinhood

'black sheep wall'

Starcraft fog of war cheat :)

black sheep wall - Starcraft

glittering prizes - Warcraft

Great Games!

dyddy donkey kong snes

ahhh the MK blood code lol how could i have forgotten that

Contra, Doom and then Sims. Yes, in that order. :)

Up, Up, Down, Down, Left, Right, Left, Right, B, A, B, A, Select, Start

I believe it was a Contra code, probably for infinite lives, but I actually forget what it gets..

I'm not sure which game this was I think it may have been for mortal combat for the megadrive to access a cheat menu, it was called the dullard code
D,U,L,L,A,R,D
Hence the Dullard code.

There is only one cheat code I need when I play a video game:

3008db630000

Game Shark code for invincibility.

Barbie Explorer PS2

Thats the one I was going to pick.

That code was pretty odd though.. (JUSTIN BAILEY)

The second you got an energy tank, you had em all.

And wasn't there something else... if you picked up a missle, it kinda screwed you up? Hm, it's been a while.

Glittering prizes, Warcraft...1? 2? I forget now.

A+B 50 times in Final Fantasy to play the slide puzzle.

Same here!
