N64Digital Installation Instructions

This kit is for advanced installers only. Install at your own risk. We cannot be held responsible for damage to your console and/or kit. Each kit is individually tested and confirmed working before being shipped out.

Before you begin:

N64Digital is compatible with all N64 models/regions; with the exception of Pikachu models.

The N64Digital requires a small case cut for the mini HDMI connector. A separate company, Laser Bear, has created a no cut solution, https://laserbear.net/shop/ols/products/n64-digital-no-cut-mod. Please be aware that both Analog and HDMI cannot be used at the same time when using the no cut solution.

Please review the installation video. Always reference these install docs and use the video as an aid for techniques on how to preform the required steps.

Kit includes:

  • N64Digital PCB
  • RCP Flex
  • RGB Flex
  • Plastic Spacer
  • Foam Block

Items required

  • Temperature Controlled Soldering Iron
  • Leaded Solder
  • Non Corrosive, No Clean Flux (I recommend Kester 959T)
  • 99% Isopropyl Alcohol
  • Multi Meter
  • Miniature File Set & Exacto Knife (Cut Version)
  • Kapton Tape or electrical tape
  • 28 or 30 AWG wire
  • 4.5mm Gamebit Adapter
  • P1 & P2 Screwdrivers

Step 1 - Console Disassembly

Remove all gamebit screws on the bottom of the console to remove top case.

Remove all screws and remove motherboard:

Step 2 - Fitting the N64Digital PCB

If using the no cut version, skip to Step 3

Align the N64Digtal board in the case and lightly mark the case with an exacto knife.

Slowly file in-between the knife marks on the case. Do this step very slow, constantly checking the fit. The Mini HDMI holds need to have a semi-tight fit. If the mod board fits too tightly, file away the burrs on the PCB from the assembly process. Refer to the installation video for more help. https://youtu.be/LJ5PXZjXLVE

Once done filing, insert the plastic spacer followed by the board. Make sure the board sits completely flat in the N64 case.


Step 3 - Soldering the RGB Flex

If you already have an RGB mod or do not want to add RGB support - proceed to step 4

NUS-CPU-01, NUS-CPU-02, NUS-CPU-03 and NUS-CPU-04 motherboards needs. C22 & R14 needs to be removed.

Solder the RGB Flex cable into place.

Slightly bend the RGB flex like the image below. Do not crease the flex.

Step 4 - Soldering the RCP Flex

Align the flex on the RCP to pin 6.

Solder the flex cable. If this is your first time soldering a flex cable like this, please refer to the video for specific techniques. https://youtu.be/LJ5PXZjXLVE

Use a multimeter to confirm there is no continuity between adjacent pins. If a direct short is found, clear the bridge and check again.

Hookup RC, RST and CON connections from the flex cable to the PIF

Some late model consoles require a different connection to the CON. If your console looks like the images below solder the CON wire to the via instead of PIN16 on the PIF.

Slightly bend the RCP flex aligning it to the multiout. Refer to the image below.

Solder the flex arm to the 5V leg. Refer to the image below.

Step 5 - Testing RCP flex installation.

Insert the foam over the multiout pins. If using the no-cut version, cut the foam in half in terms of height.

If you have a PAL console, solder the jumper found on the N64Digital PCB.

Install the bottom shield on the N64 motherboard and install the motherboard into the N64 Case. No Cut: Install the plastic spacer and N64Digital Board into the N64 case, then place the N64 Motherboard on top, do NOT use the bottom shield.

Lift the FFC GENTLY connector tabs and install the RCP flex into the N64Digital board. Do not plug in the RGB flex, just keep the flex out of the way.

Insert game cart, mini hdmi cable, jumper pak, and controller into port 1. Double check jumper pak is correctly oriented. Verify there is no short between 3.3V and GND before moving on.

Insert N64 power supply then power on the console. Do not leave the console powered on for more than 30 seconds since the heatsink is not installed. Verify you get an image on the screen, and open up the N64 Digital OSD using: L Trigger + R Trigger + DPad Right + C Right. Confirm everything works, including sound.

After testing, remove the game cart, power supply, controller, and jumper pak.

If you do not get video and/or audio, verify the audio/video work using a composite video cable + analog audio.

  • Composite doesn't work - one of two things is wrong. Bridges on the RCP flex or a poor connection with the jumper pak / game cartridge.
  • Composite does work - then the issue is related to mini hdmi to hdmi adapters. Also try another TV just to rule out any issues.

DO NOT continue on until video and audio are working properly.

Step 6 - Clock Control (Optional)

The N64Digital can recreate the original N64 clock that is sent to the RCP. With this control you can switch between PAL and NTSC frequencies when using an ED64 that has UltraCIC . Official games and older ED64 that use donor CIC will need a PIF replacement to boot out-of-region games.

Lift the pin based on your N64 motherboard revision below.

Early NTSC and PAL consoles

Late Model NTSC & PAL consoles.

Close the jumper on the RCP flex cable.

Step 7 - Reassemble the console

Install a small piece of kapton or electrical tape on the top shield.

Install the RGB flex into the FFC connector. Be extremely gentle. It is recommended to use tweezers to help you install it.

Assemble the console in reverse order from disassembly. If you do not remember where the screws go, follow the end of the installation video https://youtu.be/LJ5PXZjXLVE

Congratulations! Enjoy the N64Digital and we appreciate your support.
