Noclip: One of the few cheats that is still consistently seen in gaming is the No Clip mode in first person games, which enables you to walk through walls and sometimes find things that the programmers have hidden such as John Romero's severed head in Doom 2 and Elexis Sinclair masturbating up close in SiN.
Originally the concept was known as idspispopd, then idclip. Id Software's John Carmack coined the clip term because he considered hitting an in-game wall to be "clipping a movement vector." The first time the now standardized term was used as a cheat was probably in Carmack's series Commander Keen.
Justin Bailey: There are two passwords in the original Metroid that offer something great. One gives you lots of power-ups, and one strips Samus down to her bathing suit. Guess which one is more famous?
Passwords were used in games when memory wasn't available for save files, and as a dedicated Mega Man fan I can assure you that they sucked. Metroid had an insanely random password system to control variables, but everyone can remember Justin Bailey and blank spaces for the second line. That's why the password has remained in gamer's mind today. But who is Justin Bailey?
No one named Justin Bailey was a part of the development process of Metroid, and contrary to rumor Just In Bailey is not Australian slang for being in a bathing suit. Believe it or not, the name is a complete fluke, a coincidence of the Metroid password system. It was discovered by accident early on and was easy to remember.
Second Quest: In the original Legend of Zelda, once you beat the game you got access to a second quest where dungeons and items were in different places and the game was slightly harder. You could bypass straight to this quest by entering your name as ZELDA on the title screen, forever contributing to the idea that Link's name is Zelda.
Have you ever stopped to wonder why there is even a second quest in the first place? It was because one of the most iconic games in Nintendo history mistakenly only used half of its available memory. Not wanting to just left it all go to waste, the developers used it to create an entirely new adventure with existing assets, and made it as easy to find as possible so gamers could enjoy either adventure at their leisure.
