# Plugins

## Introduction

MAME supports plugins that can provide additional functionality. Plugins have been written to communicate with external programs, play games automatically, display internal game structures like hitboxes, provide alternate user interfaces, and automatically test emulation. See Lua Scripting Interface for more information about MAME’s Lua API.

## Using plugins

To enable plugins, you need to turn on the plugins option, and make sure the pluginspath option includes the folder where your plugins are stored. You can set the plugins option in an INI file or on the command line. You can set the pluginspath option by selecting Configure Options from the system selection menu, then selecting Configure Directories, and then selecting Plugins (you can also set it in an INI file or on the command line).

Many plugins need to store settings and/or data. The homepath option sets the folder where plugins should save data (defaults to the working directory). You can change this by selecting Configure Options from the system selection menu, then selecting Configure Directories, and then selecting Plugin Data.

To turn individual plugins on or off, first make sure plugins are enabled, then select Configure Options from the system selection menu, and then select Plugins. You will need to completely exit MAME and start it again for changes to the enabled plugins to take effect. You can also use the plugin option on the command line, or change the settings in the plugin.ini file.

If an enabled plugin needs additional configuration, or if it needs to show information, a Plugin Options item will appear in the main menu (accessed by pressing Tab during emulation by default).
