Hello! I asked this question on Hardware with no luck and searched Google so I'm asking here. Is it possible to mod a Sega Master System Control Joystick to work on a CV with a y cable in port one so both buttons work like a CV controller? If so how is it done? Or even a Sega Genesis 3 Button Joystick or even a NES Advantage? I have very limited knowledge about how to do this and would appreciate any help in how to do this if possible. Or does anyone know how to do this? Thanks for any help with this problem!
