Cheating (video games)
From Wikipedia, the free encyclopedia
Cheating in video games is a process whereby a player of a video game creates an advantage beyond the bounds of normal gameplay, usually to make the game easier.
Typical cheats include unfair advantages such as invulnerablility ("God mode") or an infinite amount of some resource such as ammunition. Cheats may also create unusual or interesting effects which do not necessarily make the game easier to play, such as making enemies tougher. Cheats often take the form of 'secrets' placed by game developers, usually to reward dedicated players.
Cheats may be activated from within the game itself (a cheat code implemented by the original game developers); or created by third-party software (a game trainer) or hardware (a cheat cartridge).

[edit] History
Cheating in video games has been around for almost the entire history of videogames. The first cheat codes were put in place for play testing purposes. Playtesters had to rigourosly test the mechanics of a game and introduced cheat codes to make this process easier. An early cheat code can be found in Manic Miner, where typing "6031769" (the phone number of the developer, Matthew Smith)[1] enables the cheat mode.
[edit] Cheating on early home computers
Even on early gaming systems such as the ZX Spectrum, cheating was prevalent, even a necessity (such as in the case of Jet Set Willy).[2] A variety of different methods were used.
In a computer game, all numerical values are stored 'as is' in memory. Gamers could literally reprogram a small part of the game before launching it.[3] In the context of games for many 8-bit computers, it was a usual practice to load games into memory and, before launching them, modify specific memory addresses in order to cheat, getting an unlimited number of lives, immunity, invisibility, etc. Such modifications were performed through POKE sentences. The Commodore 64 and ZX Spectrum also allowed players with the proper cartridges or Multiface add-on to freeze the running program, enter POKEs, and resume. Some games tried to detect the Multiface, and refused to load if it was present. The earliest models had no ability to "hide". Later revisions either included a switch, hid if you opened and closed the menu before loading the game, or automatically hid.
For instance, with "POKE 47196,201" in Knight Lore for the ZX Spectrum, immunity is achieved. Magazines such as CRASH regularly featured lists of such POKE instructions for games. In order to find them a hacker had to interpret the machine code and locate the critical point where the number of lives is decreased, impacts detected, etc. Sometimes the term POKE was used with this specific meaning.
Early gaming magazines such as Your Sinclair included sections containing the latest tips and POKE cheats.
Early cheating was largely exploited by technology-orientated players due to the difficulty of early cheats. However, a cheat industry quickly emerged as gaming systems evolved, through the packaging and selling of cheating as a product. Cheat-enablers such as cheat books, game guides, cheat cartridges helped form a cheat industry and cemented cheating as part of gaming culture.[4] Cheating was not universally accepted in early gaming however. Gaming magazine Amiga Power took a very strong opinion on cheating, condemning cheaters. They took the stance that cheating was not part of their philosophy of fairness. They also applied this in reverse; games should not be allowed to cheat the player, either.
[edit] Cheating on modern home computers and consoles
Cheating is very popular in modern videogames, with several magazines dedicated to listing cheats and walkthroughs for consoles and computer systems. POKE cheats have disappeared and have been replaced by trainers and cheat codes. By and large, the majority of cheat codes on modern day systems are implemented not by gamers, but by game developers. The reasons for this are relatively clear:
- The establishment of a cheating culture has created expectancy from gamers for video games to contain cheats.
- Cheats in single player games increase a game's replay value for the gamer.
- Game developers understand that many people do not have the time to complete a video game on their own,[5] and therefore cheats make a game more accessible and appealing to a casual gamer.
- An example of someone who doesn't have time to complete a video game on their own is a game reviewer working to a tight deadline. Cheat codes will enable the reviewer to experience more of the game content in the limited time available, and therefore (hopefully) produce a better review.
- With the rise in popularity of gaming, cheating using external software and hardware raises a number of copyright legal issues related to modifying game code.
[edit] Typical effects of cheats
[edit] Invulnerability
Invulnerablility ("God mode") is a state wherein the player character is invulnerable to damage. A variation of this is "Buddha mode" where the player character gets damaged or hurt but cannot die (health stops decreasing when it reaches 1).
[edit] Invisibility
Invisibility in a video game causes enemies to not see the player character, in order to avoid being attacked by them, such as the "notarget" code in some first-person shooters.
[edit] No-Clip or flying
No-Clip disables collision detection so the player character can pass through walls or objects, inheriting a rather ethereal quality to playing the game. Flying allows the player to move freely about in the game's space, even up and down, as if walking through air.
[edit] Infinite resources
An infinite amount of some resource such as ammunition, lives, or money.
[edit] Addition to weapons or inventory items
There are ways of editing a game save file to add certain useful items to your inventory or give your player more weapons. Save files can also be edited to place the player character in a different area in the game.
[edit] Unlockable items and characters
Some cheats can unlock hidden items or unused content in the game. In beat 'em up games it is common for characters to be unlockable.
[edit] Unusual effects
Cheats may create unusual or interesting effects which don't necessarily make the game easier to play. For example, one cheat in Jurassic Park: Operation Genesis makes dinosaurs appear 'undead'. In other games, a cheat may make the game harder to play; for instance one could give the enemy special abilities, add a harder difficulty, or give the player a disadvantage such as low health points. In a few games the player is humourously penalised if they use cheat codes originally for another game; for example, using cheat codes from Doom in Descent would result in a sarcastic message from the programmers on screen. Similar effects also occured if codes from Descent were attempted to be used in it's sequels.
Some games allow the player to enter a code to change what the character is wearing or to change the character itself, but not enhance the progress of the game. For example, most of the Grand Theft Auto games allow the player to enter a code to make the character change into an NPC. Another unusual cheat code in the Grand Theft Auto games is the ability to make the people of the town start rioting.
Effects such as this which are intentionally included in the game are known as Easter eggs. One example of this is hidden level 'warps' in the original Mario Bros..
Some games such as Tekken Tag Tournament also have handicap settings which can set health higher or lower for each individual player. If one were unaware of this setting, it could be considered cheating as the other player could give themself an unfair advantage.
[edit] Cheating Methods
[edit] Cheat code
Cheat codes are cheats that may be activated from within the game itself. Most common entry points are in a developer console, a code entry dialog, at title screens, or in-game. Cheat codes are often sequences of button presses or textual commands, depending on the input device. Unlike other cheating methods, cheat codes are implemented by the game developers themselves, often as a tool to playtest certain aspects of the game without difficulty. For example, the Konami Code was built in the game Gradius gave the player a full set of powerups because the developer, Kazuhisa Hashimoto, thought the game was too hard to play during testing.[6] Some games allow cheat codes to be unlocked when a player has enough of some kind of points or money. Examples of this are the unlockable secrets in Jak 2 and Jak 3 that modify the player character's appearance, etc.
[edit] Modification of game code
Activation may take the approach of modifying existing game code.[7] In the case of Jet Set Willy on the ZX Spectrum computer, a popular cheat involved replacing a Z80 instruction DEC (HL) in the program (which was responsible for decrementing the number of lives by one) with a NOP.[8]
[edit] Modification of game source code
There are some open source games such as BZFlag that have their source code freely available. A player could take this code and rewrite it so it either includes cheats or applies a cheat to the game automatically.
[edit] Trainers
Game trainers are programs made to modify behaviour of a computer game, usually using addresses and values, in order to allow cheating. It can "freeze" a memory address disallowing the game from lowering or changing the information stored at that memory address i.e. health meter. It simply manipulates the data at the memory addresses specified to suit the needs of the person cheating at the game. These methods of cheating are often less reliable than cheat codes included into a game by its creators; certain programming styles or quirks of internal game logic, different release versions of a game, or even using the same game at different times or on different hardware, may result in different memory usage and hence the trainer program might have no effect, or stop the game from running altogether.
In the 1980s and 1990s, trainers were generally integrated straight into the actual game by cracking groups. When the game was first started, the trainer loaded first, asking the player if he/she wished to cheat. Then the code would proceed to the actual game. In the cracker group release lists and intros, trained games were marked with one or more plus signs after them, one for each option in the trainer, for example: "the Mega Krew presents: Ms. Astro Chicken++". Modern trainers append their titles with a single + and a number, as many have several functions. The number used represents the number of modifications the trainer has available, eg. 'infinite cash' or 'instant research'. For example: "Final Fantasy VII - Ultima Edition +50 Trainer".
Modern trainers also come as separately downloadable programs; instead of modifying the game's programming directly, values stored in memory are changed.
[edit] Hardware
A cheat cartridge is attached to an interface port on a home computer or console. It allows a user to modify the game code either before or during its execution. An early example is the Multiface for the ZX Spectrum, and almost every format since has had a cheat cartridge created for it; such as Datel's range of Action Replay devices. Another popular example of this is Game Genie for NES, Super Nintendo, Game Boy, and Game Gear game consoles. Modern disc-based cheat hardware include GameShark and Code Breaker which modify game code from a large database of cheats.
[edit] Emulation
Some emulators such as VisualBoyAdvance, Nestopia, Snes9x, and Project64 allow players to modify game code as the game is running to cheat. Some even emulate cheating hardware such as Game Genie. Emulators such as MAME take this a step further, by introducing menus specifically for cheating on a particular game. One huge advantage of emulators over unaugmented authentic hardware is that they are often able to save the state of the entire emulated machine at any point, effectively allowing saving at any point in a game even where no facility for saving and restoring progress is provided by the game itself; additional hardware "instant replay" devices for some consoles also allow such behaviour.
[edit] Saved game editors
Programs exist that offer the facility to change attributes held within a game's save profile. It can allow someone to uncover secrets, discover things cut from games and modify characters.[9] For example, on the game Elite, utilities exist that allow the number of in-game credits to be modified, or additional equipment to be acquired. Hex editors were formerly quite a popular means of editing saved game files (e.g. to give the player a large sum of money in strategy games such as Dune II). However, with the rise of dedicated game-editing utilities, hex editing as a means of cheating in games has become comparatively unpopular.
[edit] Strategy guides
Strategy guides are instruction books that contain hints or complete solutions to specific video games. The exact meaning of a "strategy guide" these days is very vague, as most could be easily ranked as "walkthroughs" or "hint collections". Some people consider using a strategy guide a form of cheating. This usually applies to adventure or role-playing games where a puzzle may need to be solved. Strategy guides reveal the answers to puzzles and give hints on how to pass certain scenes in a game. Some guides even include a list of cheat codes for the game.
[edit] Cheating in online games
Cheating exists in many multiplayer online computer games. While there have always been cheat codes and other ways to make single player games easier, developers often attempt to prevent it in multiplayer games. With the release of the first popular internet multiplayer games cheating took on new dimensions. Previously it was rather easy to see if the other players cheated, as most games were played on local networks or consoles. The Internet changed that by increasing the popularity of multiplayer games, giving the players anonymity, and giving people an avenue to communicate cheats.
[edit] Aimbots
An aimbot, sometimes called "auto-aim", is software used in online multiplayer first-person shooter games that assists the player in aiming at the target. Since it gives the user an advantage over unaided players, it is considered a cheat.
[edit] Twinking
Twinking is the practice of passing on valuable items not normally available at player's character's level. Such activity is often employed by "power levellers" in games such as EverQuest in order to quickly increase the rate at which experience points can be accumulated and therefore the corresponding progression within the game.
[edit] Macroing
Macroing is when a player uses a script called a macro, which automates player actions, to automatically find items or defeat enemies for the player's advantage. This is common in online multiplayer games such as RuneScape or World of Warcraft.
[edit] Sale of online currency
The prevalence of massively multiplayer online games (MMORPGs) such as EverQuest has resulted in the trading of in-game currency for real world currency.[10] This can lead to virtual economies. The rise of virtual economies has led to cheating where a gamer will cheat to gain large amounts of ingame money which the player will then trade for real cash. One common method of doing so is through macroing, where a player will write a script to automate an action which generates cash.[11] The Terms of Service of most modern online games now specifically prohibit the transfer of accounts and/or sale of in-game items for 'real-world' money.
[edit] Prevention of cheating
Prevention of cheating in singleplayer games is practically non-existent, shown by the fact that most cheat codes are implemented by game developers themselves. However cheating on online games is common on public servers and to this extent some online games , such as Battlefield 1942 include specific features to counter cheating exploits, by incorporating tools such as PunkBuster or VAC (Valve Anti-Cheat). Prevention of cheating is an important feature on most modern online games. It is especially important during online gaming tournaments, where a cash prize will often be at stake.
[edit] Cheating on consoles
Since modifying a game's code is much harder on a console game than on a computer game, cheating on a console mainly appears in the form of cheat codes and cheat cartridges. Cheat codes in console games are usually activated in a slightly different manner than computer games, owing to the different forms of input (game controller vs. keyboard and mouse). Therefore, console cheat codes are usually activated by a certain combination of button presses on the game controller. Cheat cartridges are also popular on consoles. For example cheat cartridges (or CDs) were and are available for all the major sixth generation consoles, such as the Sony PlayStation 2.
[edit] Legality of cheating
Cheating in a game usually involves cheat codes, where the manufacturer has implemented a certain code that grants the player some advantage. However, some cheats involve the use of an external program, most commonly a trainer, and this raises a number of copyright related legal issues. These issues were brought up in the case Lewis Galoob Toys, Inc. v. Nintendo of America, Inc., where Nintendo sued Lewis Galoob Toys stating that its cheating device, the Game Genie, created derivative works of games and violated copyright law.
[edit] Prevalence of cheating in video games
Cheating has taken place on almost every videogame that has ever been created. A casual gamer, if stuck at a place in a videogame, will often use a cheat code to get past it. The widespread nature of cheating is shown by the popularity of game guides, sites such as GameFAQs and cheat sections in almost all videogame magazines.
Cheating is often nowadays not simply considered a way to finish a game but a way "to get more out of the game, kind of like buying a special edition DVD where you get extra stuff."[12]
Cheating as a fact of videogames has been helped to gain acceptance by the open-ended nature of modern videogames, such as Grand Theft Auto:San Andreas, where cheating can often increase the user experience and increase how long a game is played. Conversely, cheating can also shorten the playtime of some games; a 'walk through walls' code effectively removes whatever barrier (such as a locked door or a long and difficult path) the game world contains, making bypassing the 'block' an almost trivial task.
