The official reference frontend for the libretro API.
RetroArch provides a variety of advanced user-facing features and powerful configuration capabilities to programs that target the libretro API. While a majority of these programs are emulators for retro gaming consoles, various gaming engines and other multimedia applications are also represented. The programs, known as "cores", can be downloaded and updated directly from RetroArch's built-in Online Updater.
RetroArch defaults to a gamepad-friendly 10-foot/leanback interface that is perfect for use with living-room and home theater PCs, but there is also a more traditional keyboard-and-mouse interface available by pressing F5.
RetroArch is written in portable C and licensed GPLv3.
