Cheat Engine:Plugin System
From Cheat Engine
Cheat Engine comes with a plugin system so developers can add extra functions and features to ce without having to code in Delphi (Any language that can create standard DLL's with normal exports can make plugins for ce), or having to share their sourcecode.
To make use of the plugin system you need to create a dll that exports 3 functions: GetVersion, DisablePlugin, and InitializePlugin
Note: Unless stated otherwise, all function calls use the stdcall calling mechanism.
