I purchased a new arcade fightstick (the umvc3 hori one) off of amazon a month or so ago. the rt button (the one i use for assist 2, not one of the most frequently used buttons) suddenly stopped working. One match it was fine and then the next it stopped registering. The button will click in just like the other keys but will not register as being pressed. What is causing this and how can i get it fixed?
Try opening the stick and check if the wires attached to that button fell off.
