How to Play Retro Games on Your Modern Mac with OpenEmu Like a Pro

What is OpenEmu?

OpenEmu is an open-source emulator especially for the Mac OS, released in 2013 by your OpenEmu Team. This multi-video game system provides an interface for hardware emulation on many consoles such as the Nintendo Entertainment System, Genesis, Game Boy and more. Its architecture allows other developers to add new kernels to the core system without reporting specific APIs for Mac OS. OpenEmu displays boxes for each game and automatically sorts them on one platform. This allows you to create playlists of your favorite games by category on various platforms, and to unite the controller circuits for each of the systems that are copied – all with an easy to understand and attractive interface. Best of all, OpenEmu handles the main emulation engine behind each platform.

Downloading of ROMs

OpenEmu ROMs

OpenEmu can play games, but you have to download them separately. OpenEmu supports games for Atari, Game Boy, NES, Nintendo DS, Nintendo 64, Genesis, Sony PlayStation, Sony PSP, Super Nintendo and many more. After you find the ROM, open the App Store and download The ‘Unarchiver’, a free program that allows you to open ROM packages.

You can add games to OpenEmu by dragging ROM to the main interface window. OpenEmu is looking for an art box. However, if you can’t find it, use Google Image Search to find your own. Download it to your desktop and drag the image to ROM with colorful lines. New image replaces it. OpenEmu includes a number of personalized games, each of which looks and feels like the classic console version. Open the main program menu and select the Homebrew tab to see a list of available games. Classic Kong Complete, Pac-Man, Super Bat Puncher, and many others feel a part of your old school collection.

Preparation of controllers

OpenEmu Controller

Playing the great games with a typical Mac keyboard is boring, you can switch to the high-end controllers. OpenEmu shows that it is compatible with USB or Bluetooth controllers that are compatible with HID. OpenEmu automatically maps controls for PlayStation Dualshock 3 and 4, Nintendo Switch Pro controllers, and many other legacy systems. The Xbox One controller is compatible with downloadable drivers. If you have a compatible controller, configure it by clicking OpenEmu> Settings> Control. From there, you will see a tree wallpaper with a system selection drop-down menu. When you select a system, the image console control is displayed with the appropriate memory controller on the left. Then connect the USB controller or connect via Bluetooth, and on the Gamepad menu, click the Input menu to select the USB controller. Now click on each field and set the action to the appropriate button on your controller. This will ensure that your controller is properly connected to game control, regardless of which game you are playing.

With Mac, OpenEmu is a fantastic option, supports many different systems and has a great user interface.  If you own a Mac and like retro games like Galaga, Berzerk, Centipede, Contra, Dig Dug, Donkey Kong or Frogger, you might find that there are very few video game emulators specifically made for Apple Macs. Currently, you can only play this retro game through your openEmu on your Mac. It’s not an emulator, but a software package that creates a simplified environment for stores, a vintage-themed design interface that reminds Apple iTunes. Usually, the front end requires an emulator to play ROM from the downloaded game.
