I see that Librelec now works on a Raspberry pi 4. I currently have a nightly build of Retropie on my Pi4 . I am wondering if I can something like the below.
Boot the Pi
Select either LirreELEC and KODI or Retropie as the OS.
Finish Boot.
From menu select reboot and end up at the select screen.
Also wondering if I get a controller to connect via bluetooth with Retropie will it then work with LibreELEC as well?
