Can You Play Mk One With One Controller On Switch? Unplug your Nintendo Switch's joy-cons. Press the Joy-Con's SL and SR buttons while selecting "Controller" from the HOME menu. By doing this, the Joy-Con will be registered as "horizontally held," allowing you to use just one Joy-Con. Two people can play with a single pair of Joy-Cons if both the left and the right Joy-Cons are registered. You may also access the "Controller" option from your KORG Gadget's "System" menu.
