trying to get gamepad/joystick to control Player2....help

[mahalos]

So here's the deal.....

I'm building a cocktail cab at the moment....well actually just a mock-up at the this point in time    http://forum.arcadecontrols.com/index.php?topic=87362.0

Now my young son likes playing a lot of newer vertical shooters and likes me to join in.....unfortunately i'm on the other side playing upside down just to keep him happy.

So i figured i'd use an old USB gamepad that i have and use so i can play right side up and sit next to him,  the only problem is i can't get it to control Player 2, it controls Player 1 by default. I have had a good search but can't find any option for enabling a joystick for Player 2 only.

...any help is appreciated
