How can this possibly be any good for any first person shooter?
They're not!
What a piece of crap and a dumb idea!
They are!
...... any way we can use this with Mame? 
Don't bother.... Like you said, it's a piece of dumb ass crap!
They were originally released by Act Labs a few years ago. Nobody bought them because they're so crap. Leaning a gun from left to right on the desktop like a joystick is hardly FPS.
