The latest version of SDL, 1.2.12, is available to download from the SDL website. Anyone using Mac OS X and supporting joysticks in their game should download the update because it fixes a joystick calibration bug. When starting a game, SDL would record joystick axis events when the joystick was not moved, causing movement in the game with no joystick movement. The only way to stop the unwanted movement was to move the joystick up, down, left, and right. The 1.2.12 update eliminates the unwanted movement, making joysticks work the way you would expect on Mac OS X.
