but SR and SL do not workYes you can search for "split" in the retroarch config file in a text editor (from your PC) and set it to true, and set max users to 2 in retroarch, also I remapped the menu to start+select and put select on analog click (the left joycon need - to be remapped to start) so I can enter the menu when playing with split joycons
EDIT only works on nightly!
