RetroArch can be a challenge to set up, but here we've made it as easy as possible. This is the most straightforward and easy to understand Retroarch tutorial on YouTube.
The tutorial uses LaunchBox to present your games and their box art on a shelf, and allows you to easily launch them in Retroarch.
The tutorial shows you how to add Super Nintendo games, and how to add more platforms going forward. We cover automatically launching games fullscreen, input options, cores, and more.
