So today a thought occured to me, since the mouse is ALREADY designed to act as a lightgun in emulation, why hasn't anyone developed an actual product yet? I know aimtrack produces a lightgun with similar function, but you have to have that bar, plus they are not exactly cheap. It just seems like a no brainer, you just need a gun that the PC thinks is a mouse, trigger is left click, and a second button for right click.
I've been trying to find something like this, but no luck. Has anyone here developed such a thing?
