Uploaded byBlowFlies


OpenEmu for macOS and iOS is an open source Emulator project whose purpose is to bring macOS game emulation into the realm of first class citizenship.

The project leverages modern macOS technologies, such as Cocoa, Core Animation with Quartz Composer, and other third-party libraries.

One third-party library example is Sparkle, which is used for auto-updating.

OpenEmu uses a modular architecture, allowing for game-engine plugins, allowing OpenEmu to support a host of different emulation engines and back ends while retaining the familiar macOS and iOS native front end.

The beta version is now aviable on the button link below also for iPhone and iPad devices.


Currently OpenEmu can load the following game engines as plugins:
