OpenEmu is an open source multi-system game emulator designed for macOS. It provides a plugin interface to emulate numerous consoles' hardware, such as the Nintendo Entertainment System, Genesis, Game Boy, and many more. The architecture allows for other developers to add new cores to the base system without the need to account for specific macOS APIs.

Version 1.0 was released on December 23, 2013, after a lengthy beta testing period.[1] Numerous incremental updates have been released since then, with plans to incorporate support for more consoles in future releases. Some of these in-development cores are available to download in an optional "experimental" cores build (released alongside the regular, "standard" version), containing support for such consoles as the Nintendo GameCube and Wii.

History

OpenEmu first started in 2007 as OpenNestopia, a port of the NES/Famicom emulator Nestopia done by Josh Weinberg.[2] Weinberg and his friend, Ben Devacel, began searching for more developers to port other emulators to macOS, which led to the name change to OpenEmu, to better describe the multi-system emulator.[3]

As of version 2.0 OpenEmu requires OS X 10.11 and higher as minimum requirement to run. This has been the biggest release since 1.0 that included 16 new emulators along with hundreds of bug fixes and features.

As confirmed by the developers of OpenEmu on their official Reddit thread, Sega 32X-CD hybrid games (versions of games that could use a 32X cartridge and Sega CD at once, such as Night Trap, Corpse Killer, and Fahrenheit) are not supported. Users are prompted with a "This game requires the Sega 32X attachment" error if attempted.[4]

Features

OpenEmu features a backend that uses multiple game engines while maintaining the familiar, native macOS frontend UI. It also uses modern macOS technologies such as Cocoa and Quartz.[5] A unique feature of OpenEmu is its ROM library, which allows one to import ROM files and view them in a gallery type setting, similar to iTunes. Game info and cover art can be automatically added from OpenEmu's databases.

OpenEmu includes the following features:

  • High-quality OpenGL scaling, multithreaded playback, and other optimizations[6]
  • Real-time 3D effects and image processing
  • Graphic filters to enhance display
  • Full-screen support
  • Ability to play multiple ROMs at once
  • Ability to scan attached disks for ROMs
  • Automatic downloading of game info and cover art
  • A fully featured library, supporting multiple views, collections (categories), and game ratings
  • Optional automatic organization of ROM files within the library folder
  • Full save state support, including automatic save states
  • Enhanced gamepad support

Reception

Upon its 1.0 release, OpenEmu was positively received, and subject to much online press coverage, praising the software's UI, features, and ease of use.[8][9][10][11] In particular, it was praised by the gaming community for "[bringing] the idea of an emulator for a mainstream, general audience to reality".[12]

As of August 16, 2018, OpenEmu has been downloaded over 10,000,000 times since its version 1.0 release, making it one of the most popular multi-system emulators on macOS.[13]
