Nintendo Hard part (or game), skip particularly bad sections of an otherwise great game, to screw around after you've finished a game... Or to ruin other people's fun. There are three main types of cheating in games (although the last is more about the act than the method).
- Internal Cheating: the cheat was specifically programmed into the game by its designers. There are several variants. It can be provided as a menu option, it could be unlockable by in-game achievements (or by inputting a code into a "Password" prompt), or by performing certain obscure combination of buttons or moves from the menu or within the game itself. Sometimes these cheats can do things not directly related to helping you finish a game (or even outright hinder you), such as "big head" codes, wacky color palettes, or even making a game much harder. Many of these codes were designed to assist game testers in getting through the game without too much effort, and were then left in for players to discover.
- External Cheating: cheating using devices external to the game itself, such as turbo controllers or ROM hacking devices (e.g. Game Genie or GameShark), or external applications (like Cheat Engine) on PC games. Easily the most varied form of cheating, as the most extreme types actually alter the behavior of the game code itself, not only allowing things like invincibility, but also allowing for things like turning already bizarre bugs Up to Eleven, accessing dummied content, or giving the main character change of costume (or lose some of it).
- Multiplayer Cheating: cheating while playing games with other people, goes into both of the above types, as it involves both internal (design oversights and tweaking settings to do such things as see through walls) and external (programs to alter the game to give an advantage). The most (in)famous are Wallhacks (ability to see or move through walls), Aimbots (automatically get a perfect aim at an opponent's most vulnerable areas) and Speedhacks (move much faster than is normally allowed), and, of course, in games where players are in physical proximity there are people who will steal joypads, subtly alter game settings, look at other's screens or outright get physical. It goes without saying that if you do these things with even a hint of seriousness, you deserve everything you get in return.
