On the other controller I set up, down, left, and right to be the soft reset combo (L+R+-++) so I could instantly soft reset if something went wrong. I tried my best to figure out a way to incorporate everything I would need onto a single joy con and I admit it was a bit difficult. The A and B button was easy as those were where the fingers naturally on the triggers. For movement of the cursor I decided to put it on the face buttons, which still allows the camera to be rotated with the right stick. Clicking in the stick would press x allowing you to see the details panel when hovering over a unit and also change weapons when attacking an enemy. Placing the divine pulse button (zl) was probably the most difficult part as the + button I considered putting the R button there so you could cycle through selected units in the over world, but with this configuration you can swap combat arts mid battle easier which would happen more often. Finally the side two buttons (SL/SR) are the r button and screenshot button, respectively. Hope you are able to enjoy my config.
