What ROCKNIX is
ROCKNIX is a free, immutable Linux distribution for handheld gaming devices, focused on retro game emulation. Installation involves downloading a device image, writing it to an SD card or internal storage, and booting the device. It supports local and remote multiplayer, save states, video filters and in-game touch controls on supported devices, along with custom performance and power profiles. Bluetooth audio and controller connections, HDMI and USB audio/video output, and music and video playback are included. Cloud and local network synchronization use Syncthing and rclone, while built-in VPN support covers WireGuard, Tailscale and ZeroTier. The distribution integrates with RetroAchievements and provides automatic game scraping; achievements require an internet connection, and support varies by emulator and game. Steam and Heroic Games Launcher are supported on arm64. ROCKNIX can be updated over the air from EmulationStation or manually with an update tar file.
