I just received my new Wiz and installed mame4all.  My favorite all time video game is Vanguard. (its a nostalgia thing, I played it in the arcade back in the day)  Its a side scrolling space shooter that the dpad controls beautifully.  Your ship has the ability to shoot 4 directions, front, back, up and down.  Problem is the default mapping is whacked.  I want  B to shoot forward, A to shoot back, Y to shoot up and X to shoot down, but I cannot figure out how to do this.  
Any help would be appreciated
