On the Japanese release you can. Through the game options you can select from two preset configurations. Technical - Shoulder buttons and 1st person shooter control (1 stick forward/back, 1 turns) Normal - All but reload and zoom are on face buttons and control uses only one stick.
From these you can swap out any button with another of your choosing..
Just to get further confirmation on this issue while this topic is still open (I remember when the game first came out that someone had said that this option IS available, but...) can you definitely change the aiming options (inverted/ non-inverted) in the game when it comes to vehicles?
I just want to be sure that I'll be able to (for the first time in the franchise as far as the Sandlot releases go) set my in-vehicle Y-axis aiming to "Inverted" (press down to aim up and press up to aim down) to go along with my usual on-foot Y- Axis inverted aiming controls.
