You have to press the "esc" key first... I know, It took me a while to figure it out, too.

Is there a ps vita port of this so it can use controllers/arcade sticks on both handhelds?

Still needs C-Stick and ZR/ZL support. Without it, Smash 4 is unplayable.

I have not read all the pages but i searched the thread and did not see the term "Steam" so just to confirm, I launch kitkat from steam and get to control my 3ds with my steam controller with full profile support to set custom layouts
