OpenEmu (formerly called OpenNestopia) is a free and open-source multiple systems universal game console emulator only for Mac OS. Its appearance means that the ‘It just works‘ concept has extended to the video game simulation field on Mac operating system for the first time ever. And its purpose is to bring macOS game emulation into the realm of first class citizenship.

OpenEmu has a simple, beautiful and intuitive UI, supports drag & drop operation, game libraries, screenshot feature, real-time game rewinding function, allows user to easily add, browse, organize supported game ROM files, and can connect to compatible gamepads. It enables us to play GB, GBA, NDS, PSP, NES, SNES, PlayStation, SEGA and other classic TV/handheld console games on Mac OS now.

OpenEmu utilizes a modular architecture that supports game engine plug-ins (i.e.: loads various game engines as plugins), which means it can support a large number of different console emulation engines, and simulate the hardware of different TV/handheld game consoles. It not only supports 8-bit systems, such as: Altari, Famicom (NES), Game Gear, NES, Game Boy, Game Boy Color; a variety of 16-bit systems, including Mega Drive, NeoGeo Pocket, PC Engine, Sega Genesis, SNES (SFC); as well as 32-bit systems, including Game Boy Advance, Nitendo DS, PlayStation, PlayStation Portable (PSP), Sega Saturn; but also supports the 64-bit systems such as Nintendo 64.

To this day I am still obsessed with console games rather than PC games, web games, mobile games, or any type of online games. Anyway, in this age of online games and large 3D games, I do believe the console gaming is still a fun-filled memory for most nostalgic old players. If you’re using a Mac OS and love video games much, then OpenEmu should not be missed.
