jgenesis vs ROCKNIX

jgenesis is a free, cross-platform emulator for 8-bit and 16-bit consoles. It supports Sega Genesis/Mega Drive, Sega CD, Sega 32X, SG-1000, Master System, Game Gear, NES, SNES, Game Boy, Game Boy Color, Game Boy Advance, and PC Engine/TurboGrafx-16. Save states, fast forward, rewind, and optional CPU overclocking are available on some systems. Expansion support includes Master System FM sound, the Genesis SVP chip, common NES mappers, and most SNES coprocessors. Its GPU renderer offers integer prescaling, optional linear interpolation, configurable pixel aspect ratios, blur, and anti-dither shaders. Keyboard and DirectInput gamepads are supported, including three-button and six-button Genesis controllers. Published builds require a 64-bit x86 CPU with SSE4.2 and a GPU supporting Vulkan, or DirectX 12 on Windows 10 and later. The project estimates about 300 MB of RAM for default settings. Releases come through GitHub, while commit builds remain available for 90 days and may be buggy.

ROCKNIX is a free, immutable Linux distribution for handheld gaming devices, focused on retro gaming emulation. Installation means downloading a device image, flashing it to an SD card or internal storage, then booting the device. It supports local and remote multiplayer, save states, video filters, in-game touch controls on supported devices, and custom performance and power profiles. Bluetooth audio and controller connections, HDMI and USB audio/video output, and music and video playback are also included. Cloud and LAN synchronization are available through Syncthing and rclone; built-in VPN support covers WireGuard, Tailscale and ZeroTier. ROCKNIX integrates RetroAchievements and automatic game scraping. Achievement support varies by emulator and game and requires an internet connection. Steam and Heroic Games Launcher are supported on arm64. Updates can be installed over the air from EmulationStation or manually with an update tar file. There is no formal support; the project is provided as-is through community help channels. Supported devices are listed in the wiki, and adding a device requires contributed work and direct access to it.
