I am thinking about ordering this expansion module for my Famicom. It plugs into the front accessory port on the original Famicom, providing headphone output as well as turbo fire on the original hard-wired controllers. Apparently it is a "legendary" Famicom accessory.
Has anyone used one of these or heard anything about it by chance? I think it would be the ultimate edition to my Composite, 3D Stereo Sound, Controller Cord extended Famicom.
