OpenEmu is about to change the world of video game emulation. One console at a time...

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.

Take Control
Up, Up, Down, Down, Left, Right,
Left, Right, B, A, Start

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!

Time To Get Organized
Everything in its place. Automatically

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!

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



Your game is now neatly organised and you are ready to start playing!
