'''Cheat Engine''', commonly abbreviated as CE, is an [[open source]] [[Memory address|memory scanner]]/[[hex editor]]/[[debugger]] created by Eric Heijnen ("Dark Byte") for the [[Microsoft Windows|Windows]] operating system.<ref name="aboutce">{{cite web|url=http://www.cheatengine.org/aboutce.php|title=About Cheat Engine|accessdate=2008-03-20|work=www.cheatengine.org}}</ref> Cheat Engine is mostly used for [[Cheating (video games)|cheating in computer games]], and is sometimes modified and [[compiler|recompiled]] to evade [[Cheating in online games#Anti-cheating methods and limitations|detection]]. This program resembles L. Spiro's ''Memory Hacking Software'', TSearch, and ArtMoney. It searches for values input by the user with a wide variety of options that allow the user to find and sort through the computer's memory. Cheat Engine can also create standalone [[Trainer (games)|trainers]] that can operate independently of Cheat Engine.

==Features==
Cheat Engine can view the disassembled memory of a process and make alterations to give the user advantages such as infinite health, time or ammunition. It also has some [[Direct3D]] manipulation tools, allowing vision through walls and zooming in/out, and with some advanced configuration Cheat Engine can move the [[Mouse (computing)|mouse]] to get a certain texture into the center of the screen. This is commonly used to create [[aimbot]]s. However, the main use for Cheat Engine is in single player aspect of games and its use in [[multiplayer games]] is discouraged.<ref name="CE online use">{{cite web|title=Cheat Engine :: FAQ|url=http://forum.cheatengine.org/faq.php#0|website=forum.cheatengine.org|accessdate=August 28, 2016}}</ref>

Cheat Engine can inject code into other processes and as such most anti-virus programs mistake it for a virus. There are versions that avoid this false identification at the cost of many features (those which rely upon code injection). The most common reason for these false identifications is that Cheat Engine makes use of some techniques also used in trojan rootkits to gain access to parts of the system, and therefore gets flagged as suspicious, especially if heuristic scanning is enabled in the anti-virus program's settings. Newer versions of Cheat Engine are less likely to be blocked by anti-virus programs so features like [[code injection]] can be used without problems.

As of version 6.1, Cheat Engine can produce [[Trainer (games)|game trainers]] from the tables. While trainers generated in this way are typically very large for their intended purpose, generally used for testing purposes, some have been released by trainers groups as "final" versions<ref name="cetrainers">{{cite web|url=http://deviatedtrainers.com/sniper-elite-v2-trainer|title=CE Trainers Mass Use|accessdate=2012-05-18|date=2012-05-18|work=Deviated Trainers}}{{dead link|date=August 2016}}</ref> and even some popular sites are fully based on CE trainers<ref>{{cite web|title=Cheat Engine trainers popularity|url=http://deviatted.com|accessdate=1 May 2016|website=deviatted.com}}</ref> due to the ease of trainer creation with CE.{{fails verification|reason=source doesn't mention CE|date=August 2016}} However, despite their popularity, CE trainer maker has not been updated since its implementation in version 6.1, is largely unsupported and emphasis is given on using [[Lua (programming language)|Lua]] to generate trainers. Even the trainer maker itself uses Lua scripts to generate trainers.

==Implementations==

Two branches of Cheat Engine exist, Cheat Engine [[Borland Delphi|Delphi]] and Cheat Engine [[Lazarus (software)|Lazarus]]. Cheat Engine Delphi is primarily for [[32-bit]] versions of [[Windows XP]]. Cheat Engine Lazarus is designed for 32 and [[64-bit|64]] bit versions of [[Windows 7]]. Cheat Engine is, with the exception of the Kernel Module, written in [[Object Pascal]].

Cheat Engine exposes an [[interface (computing)|interface]] to its [[device driver]] with <code>dbk32.dll</code>, a [[Library (computing)#Dynamic linking|wrapper]] that handles both loading and initializing the Cheat Engine [[device driver|driver]] and calling alternative Windows kernel functions. Due to a programming bug in Lazarus pertaining to the use of [[Exception handling syntax#Delphi|try and except]] blocks, Cheat Engine Lazarus had to remove the use of <code>dbk32.dll</code> and incorporate the driver functions in the main executable.

The [[Loadable kernel module|Kernel module]], while not essential to normal CE use can be used to set hardware [[breakpoint]]s and bypass [[hooking|hooked]] [[Application Programming Interface|API]] in [[Ring (computer security)|Ring 3]], even some in Ring 0. The module is compiled with the [[Microsoft Windows|Windows]] [[Driver development kit]] and is written in [[C Programming Language|C]].<ref name="dbksources">{{cite web|url=http://ce.colddot.nl/browser/Cheat%20Engine/DBKKernel/compileinfo.txt|title=Cheat Engine - Trac - compileinfo.txt|first=Kevin|last=Valk|date=2008-12-20|accessdate=2008-03-20|work=ce.colddot.nl [[trac]]}}{{dead link|date=August 2016}}</ref>

Cheat Engine also has a [[Plug-in (computing)|plugin]] architecture for those who do not wish to share their [[source code]] with [[free software community|the community]]. They are more commonly used for game specific features, as Cheat Engine's stated intent is to be a generic cheating tool. These plugins can be found in several locations on the cheat engine website, and also other gaming sites.<ref name="contributing">{{cite web|url=http://forum.cheatengine.org/viewtopic.php?t=5806(contracted; show full)* {{Official website}}
