key_NES is a Nintendo NES game controller “driver” for Mac OS X, using an Arduino as the hardware interface. It is built mainly to allow the use of 1 or 2 NES controllers as gamepads for video game emulators such as Genesis Plus (for Sega Mega Drive/Genesis) and Nestopia (for Nintendo NES), however it can be customized to be used with any emulator (or application). Code for the Arduino is included with the application.

key_NES was created in MaxMSP 5 and was compiled into a standalone application so you do not need to have MaxMSP to run it. It is based around converting gamepad button presses to simulated presses of the computer keyboard. This is enabled with the help of Masayuki Akamatsu‘s fantastic aki.keyboard object for MaxMSP. Since this application simply converts button presses to keystrokes, it can potentially be used for many computer tasks, when customized.
