did you used the item you get from reading the sign with the keybord controls for the first time to configurate the controller settings?
i tried but i dont know how to reconfigurate the controls and you cant change the B button since it is grayed out. on keyboard ESC equals to B on controller but pressing the B on controller does not back out from the menus like ESC does on keyboard
sorry using the keyboard, the only other buttons coming to the mind are the two in the middle
