Description
RetroArch is a free and open-source, cross-platform frontend for emulators, game engines, video games, media players and other applications. It is the reference implementation of the libretro API, designed to be fast, lightweight, portable and without dependencies. It is licensed under the GNU GPLv3.
RetroArch runs programs converted into dynamic libraries called libretro cores, using several user interfaces such as command-line interface, a few graphical user interfaces (GUI) optimized for gamepads (the most famous one being called XMB, a clone of Sony's XMB), several input, audio and video drivers, plus other sophisticated features like dynamic rate control, audio filters, multi-pass shaders, netplay, gameplay rewinding, cheats, etc.
RetroArch has been ported to many platforms. It can run on several PC operating systems (Windows, macOS, Linux), home consoles (PlayStation 4, Xbox Series X, Wii U, PlayStation 2 etc.), handheld consoles (PlayStation Vita, Nintendo Switch, etc.), on smartphones (Android, iOS, etc.), single-board computers (Raspberry Pi, ODROID, etc.) and even on web browsers by using the Emscripten compiler.
