The X and O buttons on my game are switched. How do I fix it?
This issue occurs if your PlayStation console is from Japan but you are playing an American or European version of Rock Band. In Japan, the X and O buttons are reversed to the way they're used in American and European gaming. If your game is expecting you to push X to go forward, but your console is expecting you to push O to go forward, there will understandably be some confusion. You should push buttons the way your console expects, as it is doing the steering, so even if the game is asking you to push X to go forward, push O.
In general we recommend always purchasing the same region disc, console, and downloadable content to avoid region incompatibilities such as this.
