Run into a problem recently. My Picade was working fine and I've played several hours on it but then for no clear reason one of the buttons stopped working. Then a while later the joystick wouldn't move left (up/down/right are fine). Then I went into the button configuration to see if something went wrong with the mapping but the mapping configuration isn't picking up the key presses for left and the button I use for 'fire'.
The only thing I've done is take the button out and swap it with a different button from the set... still didn't pick it up so not a problem with the actual button.
Everything else is working fine. Where do I start bug hunting (bearing in mind I'm not overly technical or a super user).
I'd appreciate any input ;)
