Wii Dual – HDMI, RGB and Component Upgrade

The Wii Dual is an internal upgrade for the Nintendo Wii that ads a true digital-to-digital HDMI output, using the GCVideo open-source project from Unseen.  It also ads RGB and RGsB support to all model Wii’s and improves the output quality of the component video output.

The board is based off Unseen’s GCVideo project, which reverse-engineered the digital chip in the GameCube’s component video cables.  All GCVideo solutions are zero lag in both analog and digital versions.

Purchase Options:

Wii Dual kits are available directly from the creator: https://shop.dansprojects.com
It’s a complicated installation, so it should be considered an expert-only install.  Pre-modded units should be available for sale as well.

Compatible Wii’s:

The Wii Dual is compatible with the following board revisions:

RVL-CPU-40  /  RVL-CPU-60  /  RVK-CPU-01 (K01)  /  RVK-CPU-02 (K02)

There are two ways to determine the model.  An easy way is to look for a Black, Light Blue, or Red Wii that include the GameCube ports.  Unless someone did a case-swap, those will be compatible.

To guarantee compatibility, you’ll need to remove the battery (just one screw) and read the motherboard revision.  As an example, the one shown here is not compatible:

GameCube Support

Some of the Wii revisions that this kit is compatible with are also backward-compatible with the GameCube.  Using the Wii Dual will get you the exact same high-quality output you’d get from a GCVideo solution for the GC.  It is also equal to the official Nintendo component cables.  In fact, unless you use your GC for the Game Boy Interface, you won’t even need a Game Cube after this!

Conclusion

The Wii Dual is for someone who wants the best quality audio and video from their Wii.  You can achieve dual outputs on an unmodded Wii using a component video splitter and you can get HDMI with a YPbPr-to-HDMI converter…but none will look and sound as clear as this.

This is by far my favorite way to play Wii games.
