Recalibrate the Controller

Recalibrate the Controller in one of the following ways:

Push RESET (or turn the system OFF and then ON) while making sure to not touch the control stick. This ensures the control stick is in the Neutral (center) position.
Press the X, Y, and Start/Pause buttons simultaneously for three seconds during game play, making sure to not touch the control stick. This ensures the control stick is in the Neutral (center) position.
Unplug the controller and re-insert it (while the system is ON).
