How do you change your aiming direction in heavy barrel
In the GP32 version of MAME, torso twisting (aiming) is done using button definition 9 and 10.
I usually set them to "select" and "start" as they are on each side of the screen on the GP32.
Under GP2X, it should be something similar? I haven't got my GP2X here at the moment.
EDIT: On the GP2X the shoulder buttons are configured to rotate your torso/gun, so there should be nothing to do.
