Recalbox vs RetroArch

Recalbox is a free, open-source retro gaming system for replaying games from consoles and computers. It advertises support for more than 100 systems and lists online play, save-anytime, rewind, instant save, scraping, overlays, shaders, a virtual keyboard, and multi-system search. Users can build their own system or buy a ready-to-play kit. Downloads are offered for Raspberry Pi, handhelds, PCs, and ODROID boards. The PC download page lists Steam Deck and PC builds at version 10.1.1, plus a 32-bit PC build at 7.2.2-Reloaded. Recalbox is designed to be easy to use, including for beginners. Tutorials, community documentation, a forum, and an FAQ provide support. Patreon supporters can receive early releases, automatic scraping, exclusive playlists and themes, and partner discounts; these features are intended for future free releases. Compatibility information covers supported systems, not every game or device.

RetroArch is a frontend for emulators, game engines, and media players, bringing them under a unified settings system. The RetroArch/Libretro project includes more than 200 cores across those categories. Its menu can group scanned games by system and display thumbnails and animated backgrounds. Common game controllers configure automatically when plugged in, and button actions can also be assigned manually.

Stackable shaders can change rendered graphics or imitate the look of CRT monitors. Built-in netplay supports hosting or joining network gaming sessions, including spectator mode. RetroArch can record gameplay to video files and stream games to Twitch or YouTube. Versions are listed for Windows, Linux, Android, iOS, macOS, and web browsers. RetroArch is free and open source under GPL version 3; the libretro API uses an MIT license. Features differ by platform and store version: the browser edition has lower performance and fewer capabilities than the full version, while Steam lacks Core Updater and thumbnail scraping and offers a selected core set.
