Today in the middle of a game, my circle pad on my original style 3DS started behaving strangely. In the neutral position, it seems to think it's being held in the down position. I've tried to calibrate the pad, and wiped system memory and nothing has helped. Bizarrely, the calibration seems to be successful, as when you move the pad in each direction the little arrows light up. But as soon as you're back on the main menu, the issue comes back. Is there anything else I can do, or is it simply that the pad is screwed and I need to replace it? Thanks.
