Introduction

Disclaimer

Disclaimer: 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.

Important Information

The kit is compatible with both DOL-001 and DOL-101

While the kit will work with the Panasonic Q its not outlined in the this guide. Make sure to grab Jesusburnsneon's [adapter] if you are doing a Q.

The doc assumes you are doing a no cut (Replace analog or digital port) installation in your GameCube.

If you are upgrading an existing GCDual or other installation and wanting to do the case cut you will need the 3D printed spacer [[1]] to mount.


Blueshell3D has created a very nice [printed backplate] that allows for full-size HDMI in the GCDual cut location. This is a great option for people wanting to keep both ports while keeping full size HDMI at the same time.

Disassembly

This guide will not go over the disassembly of the GC. Guides are available online.

Once the motherboard is free (Leave the heatsink attached unless you plan to replace the thermal pads), set it to the side. We now need to decide which port you would like the HDMI to replace. This install will remove the the digital port in the DOL-001. Removing the analog port is also the same procedure.

Insert the full size connector into the plastic mount. It will snap into place. Then secure the HDMI board with the M2 nut and screw. The M2 screw will need to be trimmed flush. Do not overtighten



Align the top and bottom shields and check the alignment with the HDMI connector. It needs to fit in to the hole, so mark and remove any of the metal shield.

I use side cutters and pliers to cut and fatigue bend the metal off.
