I am looking into a 4-way gated joystick for pac-man and cold blood (on CV SGM) and looks to be 7800 controller is the closest to what I want. Does anyone know if the Champ Keyboard adapter for atari controller to colecovision supports 2 seperate fire buttons like a 7800 controller? I read somewhere on here that there may have been two different versions, one of which supports the 7800 fully. Does anyone know if there is a way to distinguish these two models from looking at them on the web (different model #, product number, etc.). Also, there is some comments it works the same as a y-splitter cord with a standard CV controller and atari joystick, although I don't know that the pinout for the second fire button will match.
