I have a 3DS where the cursor keeps scrolling up on the main menu and in games. I have tried different games and without games installed. Using the joystick or +pad I can change direction but as soon as these controls are released the cursor goes up as if one of the controllers were stuck up. I swapped out the joystick and stripped, cleaned the metal contacts, motherboard contacts and changed the rubber pad on the +pad and still the cursor scrolls up. Is there anything else I can try?
