FQUIGGLY ... I was always pissed off at this one not working. Was posted in a couple of magazines as being a level select code or somesuch for Lemmings. Don't know if it was a hoax, or just my version was different.

COMEFLYWITHME turned the old Days of Thunder NASCAR (3D-ish) game into a flight sim.

ODIE for level skip on Supercars; POOR to have loads of cash.

And "T" at the depack screen for extra lives, invulnerability, etc on all of the very many pirate compilation floppies that formed the bulk of my youthful gaming experience.

Plus various others that have sadly flown the mental coop since.
(ohyeah ... and if you left Gauntlet II paused for 10 minutes, all of the doors unlocked and the walls turned into Exit tiles. Very handy if you ran out of keys.)

 

[Ze_Reaper_Of_Zeath]

tgm : Fallout 3 & Oblivion's "GOD MODE" cheat.

 

[tahrey]

oh and of course the good old "impulse 9", "sv_gravity" and "sv_friction" console commands in quake, along with the rather bleedin' obvious "god", "fly" and "noclip" ones...

Well let's see, I remember that the code to access the level select on the NES version of TMNT II: The Acrade Game went: a, b, a, b, up, down, a, b, right, left, a, b, start

Also not really a cheat code, but the password to the final floor in The Adventures of Lolo was DVYB.

JUSTIN BAILEY - Weird code for the original Metroid that resulted in an unarmored Samus with almost every weapon and upgrade.

I'd like to say that I remember the konami code by memory, but I always have to look it up for the exact button presses.
