Region Jumpers

The jumpers control the region of the Saturn by being connected to ground or supplied 5V in various ways. This is permanently set on the Saturn mainboard but can be overridden by cutting the ground connection or 5V supply and controlling these via a modchip.

The jumpers are usually in pairs JP1/JP2, JP6/JP7, JP10/JP11, JP12/JP13.

The jumper pairs share common pads that are connected by a thin trace. They will then have two adjacent pads, one is a ground point and the other is a 5V supply.

The below table shows which connections the common pads require to make the console a certain region.

To allow the console's region to be controller by the mod, all connections need to be removed except for JP8 & JP9, because these are the same for all regions.

Region JP1/JP2 JP6/JP7 JP8/JP9 JP10/JP11 JP12/JP13
Europe Ground Ground Ground 5V 5V
Japan 5V 5V Ground Ground Ground
North America 5V Ground Ground 5V Ground
