For the first time, the 'It just works' philosophy now extends to open source video game emulation on the Mac. With OpenEmu, it is extremely easy to add, browse, organize and with a compatible gamepad, play those favorite games (ROMs) you already own.






Why restrict yourself to just the keyboard? Although it is not a requirement, OpenEmu is best used with a peripheral gamepad or controller to interact with your games.
Via the Controller Preferences, simply auto- magically assign buttons with any generic HID compliant USB or Bluetooth game controller.
Plug in your gamepad, select it from the list… and press start to begin your adventures!
We combine some of the best emulation projects together into one beautiful unified application that simply organizes your personal games library. Watch as you drop in backups of your games (ROMs) & they are gracefully added to their appropriate library along with original box art!

Drag n’ Drop a backup game (ROM) from your Mac desktop.

OpenEmu ‘scans’ your game and begins the organisation process.

Your game is now neatly organised and you are ready to start playing!
One of the standout features of OpenEmu is how it organizes all your games into one unique, unified games library. Watch as backups of the games (ROMs) you already own are gracefully added to their appropriate library and box art is magically added. You can even create your own ‘collections’ mix and matched from different consoles.
Any generic HID compliant USB or Bluetooth game controller should work with OpenEmu out of the box. OpenEmu now automatically maps controls for the following recognized devices in our database:
PlayStation Dualshock 3 and Dualshock 4
Nintendo Switch Pro Controller
Wiimote and Wii U Pro
Xbox 360 & 3rd party (driver required)
