Sega Saturn Switchless Mod

 
This mod allows the Sega Saturn to run games from any Region, and also allows 50/60Hz switching. The best part is its all controlled by the Saturn's reset switch!
 
Parts Needed:
 
Watch the below vids for creation of the board and installation. I have listed the common Jumper locations in the chart below the videos, as well as a diagram of the board layout..

Common Jumper Locations:
 
Model1 Saturn - NZ/AUS Model1 Saturn - NZ/AUS
 
 
 
50/60Hz Wire
If the method shown in my video doesn't work on your motherboard, or the points aren't there, then you need to find the Sega IC marked 315-5690 .. Sometimes this is labelled as IC14 on the motherboard. You need to lift Pin 79 from the IC, and solder the 50/60Hz wire to that. Use the below pictures to give you a bit of a guide:
