completing this modifcation, there are many potential variables that could result in the unit that the user is
attempting to modify requiring more restorative measures. ere is also a serious risk of, injuries, and death
when working with electronics. At the time of this guide’s writing these consoles are rapidly aging, and even
working units should be recapped as soon as possible. Chemicals associated with some of these processes are
quite toxic and should be handled with care and adult supervision. Results may vary. “64HD”, “Gamebox”,

RCP Flex Cable Installation
STEP 1
Page 4
Solder the RCP ex cable starting at Pin 6 (as shown above).
Solder the ex contact to the N64 motherboard
location marked “5v” in silkscreen (shown above).
FAILURE TO MAKE THIS CONNECTION
PROPERLY WILL RESULT IN THE 64HD PCB FAILING
TO BOOT WHEN THE CONSOLE POWERS ON.
For N64 motherboard revisions 01-05 (shown
le). Use a small amount of 30 gauge wire to connect
the CTRL breakout pad on the RCP ex cable to PIN 16
on the PIF. e Reset pad isn’t populated.
For motherboard revisions 06-09 please see the next page.
e motherboard revision can be found near
the cartridge slot (shown below).

PIF 16
Page 6
Alternate PIF Location On Later Revisions
STEP 3
For motherboard revisions 06-09 you must wire the CTRL pad to a VIA located next to the PIF chip
instead of directly to the chip itself. IF WIRED DIRECTLY TO PIF 16 THE USER WILL BE LOCKED OUT OF THE
OSD. Use a gentle abrasive or razor to remove the solder mask on the VIA before tinning and making the
connection. e VIA is the 4th VIA point that is closer to PIN 15 of the PIF chip.
HDMI Daughter PCB Installation
Mount the HDMI daughter PCB to included bracket using the included M2 screws. Install the daughter
PCB’s 15 pin FFC.

STEP 4
HDMI Daughter PCB Installation
Place bracket in the bottom N64 shell(as shown above). Place bottom motherboard shielding over the
bracket.
Page 8
STEP 5
Replace the N64 motherboard. Install the no-cut A/V shroud. Install the top motherboard shield.
Remove the screws shown, line up the 64HD main PCB, and reattach the screws.
NOTE: If your motherboard is a later model that does not include these screw holes, use the included double
sided foam tape to secure the 64HD PCB down to the N64 heatsink.
