OpenEmu

OpenEmu provides a unified graphical interface for running ROMs from many classic video‑game consoles and arcade systems on macOS. It bundles a selection of open‑source emulation cores, allowing users to add, browse, and launch games from a single library that automatically categorizes titles and fetches original box art. The application supports drag‑and‑drop import of ROM files, which are scanned and placed into the appropriate system collection.

The software is designed for macOS users who own legal copies of retro games and prefer a streamlined experience with minimal configuration. It works with any generic HID‑compliant USB or Bluetooth controller, automatically mapping buttons for recognized devices, though keyboard control is also possible.

OpenEmu is released under an open‑source license, is free to use, and is considered stable. Its modular architecture relies on external emulation projects to provide support for a wide range of consoles, presenting them through a single, organized library.
