Migrating to Atmosphere is recommended, yes. With Atmosphere (and the proper signature patches), you can do just about everything you could already do with SX OS. Instead of being able to launch XCI files, you will have to install all games using your favorite title installer (TinWoo and Awoo Installer are recommended).
Hi, thanks for the reply.
I did get rid of all my .xci files and now have .nsp games. So any good guides or video's to follow to get this all set up on Atmosphere, Thanks
Also - What is the latest firmware version on the Switch that can play SXOS games? Thanks
