Equipped? No, I just picked that. The game has recognized my gamepad so I was able to move and interact using it, but no any button was opening any menus. Right stick? Well, that was super-non-intuitive.
I definitely advice You to change the input binding on both keyboard and gamepad to match the standard inputs of JRPGs made on JRPG-maker. You know, [Y] to Pause, [A] to interact and confirm, [X] for special action, [B] to cancel. And [F key] to interact please, not [E key]!
