OpenEmu is an open source multi-system game emulator designed for OS X. 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 OS X.
