Some tips before starting :
- Choose a suitable place, with space and lighting!
- Take your time
- Use suitable tools, not a soldering iron too powerful with a huge tip ...
- You will find the few equipment for this installation in our tooling section


There are different revisions of N64 motherboard. In this tutorial we work on a PAL NUS-CPU (P) -01 console which is a common model.
It is quite simple to transpose this tutorial with most revisions, but in case question do not hesitate to contact us.

In order to avoid any video problem we advise to modify your console in RGB
With composite video problems can exist. In the tutorial that follows we are working on a PAL console not modified in RGB. An additional step is necessary. This step is different and more or less complicated depending on the revision of the console ... SO the best way to avoid that, is too mod your N64 in RGB. In addition the RGB improves the graphic rendering of the N64 ...

Remove the 2 plastic tabs inside the cartridge port

Desoldering the PIF circuit of your N64
(for a PAL console it is the PIF (P) for a NTSC console the PIF circuit)

The easiest way is to use a hot air station to desolder the circuit
If you don't have one, which is likely :)
You can leverage/lift the pin of the PIF one by one. Heat the pin to lift with the tip of your soldering iron

Remove the rest of the solder with a desoldering braid, then clean the pads with isopropyl alcohol :

Installation of your PIF circuit on the Region Free kit

Check that the pins are straight and aligned. Pay attention to the mounting direction and solder the PIF pin by pin

Installation of flat cables

Method 1 - caps removing

The two SMD capacitors C34 of 10µF and C140 of 68µF must be removed in order to free up space for the flat cables.
The 2 caps need to re-installed under the board with the replacement caps supplied with the kit
This is the method we prefer, because it is easier to remove the upper shield if necessary ...

Note: on some motherboards it is necessary to remove C142 from 33µF instead of C34

(brown cap = 68µF or 100µF , black cap = 10µF)

Installation of the number 2  flat cable

To solder the flat cable we advise to first tin pad 28 and to solder the red wire. Then progressively solder the other wires without tinning the motherboard pads in advance ...

Then install the number 1 flat cable :
Note  that the pin 14 of the motherboard is not connected

The flat cables pass between the shield and the motherboard, it will be necessary to take care not to screw too much!

Method 2 - No caps removing
Create a small opening in the shield to pass the 2 flat cables

Installation of the dual frequency oscillator (DFO)

You must remove the xtal X1 from your motherboard to install it on the DFO
(17.7Mhz for PAL console, and 14.3Mhz for NTSC console)

To know : thre is no mounting direction for a xtal

Xtals installed

Lift pin 7 of circuit U7 MX8330 (or MX9911)

Note: if your console is equipped with MX8350 U17 circuit in a 14 pin package, you must also lift pin7 and connect it to point MX1 of the DFO

Installation of DFO & verification of minimum height

It is necessary to remove solder from the 2 holes of the old xtal of the motherboard, use desoldering braid. hen insert and solder the DFO

It is important to check that the distance between the DFO and the shielding plate is sufficient, if necessary cut the legs of the xtals you have installed, and check that the DFO is properly plated on the motherboard:

DFO Wiring

Connect the DFO as you see :

Installation of the kit, and connection of flat cables

Installation of the LED (optional)

Remove the original led

The longest leg of the LED is the common cathode, it is connected to ground (GND)



Check all the steps carefully before switching on your console!

Bonus step, if your console is not RGB modified

(for a PAL NUS-CPU (P) -01 console)

Open the jumper JP3 with a cutter, then solder a wire between the common point of JP2 / JP3 and the point MX1 of the DFO!
