Mad Dog Mcree (DVD)

I'v seen games like Dragons Lair for DVD, which can play on a DVD player (You use the control for selecting direction), but for a game liek Mad Dog which needs a light gun, how can you play? Do you use your forward and reverse button to move a curser around?

Does anyone have the DVD?
up down left and right controller arrows on the dvd remote... yup it sucks but with a game like mad dog mcree it really can't suck that much more than it originally had
