I got a six-button Sega Retrobit controller for my Sega Genesis mini, so I can play Street Fighter 2 better. (It also has a handy instant-menu shoulder “Mode” button kinda hidden on it.)
It says it can be used for PC, MAC, PS3, Steam, and Switch also.
Though, it’s officially licensed by Sega, (and a very accurate recreation of the old Sega 6-button controllers) it’s oddly not licensed by Nintendo for Switch, nor Sony for PS3 usage.
Does that make this a licensed unlicensed controller? :P
It works pretty good, though I haven’t tried it on Switch yet.
