Lakka is a Linux distribution aimed at turning small computer devices into retrogaming consoles. It is a minimal operating system using RetroArch as a front-end - it contains nothing more, nothing less than what's required for RetroArch and its 100+ supported consoles and standalone games.

And guess what - it runs on the Switch too, using the magic of ShofEL2 ! Prepare your SD card, boot the system and you're ready to go !
