I'm assuming the problem you are having is that your P1-Joy and P2-Joy are not registering movement in the game.
Dual joystick games list the joys as P1-Left and P1-Right, so you need to map P1-Left/Up to your left joystick's up position, P1-Left/Left to your left joystick's left position, etc...
P1-Right/Left would get mapped to your right joystick's left position, etc...
