I am intrested in trying a guncon2 on my mame cab to see how it works before I hack them for Aimtraks. Can someone point me to a how to or tell me what I need. I have a 26 Wells garnder arcade monitor and one of the first ArcadeVga cards. I do have tinted glass if that will make a difference or not. I have read about building a circuit board but not sure if I need one.
