OpenEmu
OpenEmu is free, open-source video game emulation software for macOS. It organizes game backups into a unified library, adds box art and supports collections spanning consoles. Users drag and drop backups for scanning and organization. Modular cores from open-source projects emulate systems including Atari, Game Boy, Nintendo, Sega, Sony PlayStation and Super Nintendo; the project lists 31 supported systems. Generic HID-compliant USB or Bluetooth controllers can work immediately, with automatic mapping for recognized devices. OpenEmu is intended for games users already own, and BIOS files are required. The wiki describes an experimental arcade core plugin that is strictly unsupported. The latest release page identifies OpenEmu 2.4.1 binaries as Intel-only. The official site offers a macOS (OS X) application, but the version requirement was not rendered. The project lists save states, CD audio and cheat support, while online netplay is not available.
