Science and a Sega Saturn. Using the multiplexer out of a 3 - TopicsExpress



          

Science and a Sega Saturn. Using the multiplexer out of a 3 button Genesis controller (Goodwill!), I wired it in such a way that it flips 5 volt and ground signals on the triggering of the select pin. Doing this allows the region jumpers on the bottom of the motherboard to be swapped when the select button is pressed. What this means is that when the system is first powered, it is locked in US mode. When someone holds the select line down though and powers up the system, the 74hc157 flips ground and 5v, reversing the jumpers and locking it into JP mode. TL; DR I modded a Sega Saturn to be dual-region with parts from a Sega Genesis controller.
