This isn't an easy upgrade, I offer a send in service, just email me for details. david@oldskoolconsoles.com
 
Install tips:
 
Be careful not to scrape any solder mask off surrounding the vias! Its easy to create shorts this way. I've learnt this through experience. I tend to use a brand new blade to scrape away the solder mask, you'll need some kind of a microscope setup ideally to see what you're doing.
 
Testing tip:
 
To get to the diagnostics mode, you'd need to launch the GCVideo-DVI updater through the Homebrew Channel to display the video test pattern, then press L+R+X+Y on a GameCube controller to get to the GCVideo menu, select "About -> Update firmware" and immediately hold the R trigger until the diagnostics screen appears. There's some more information on it here: https://github.com/ikorb/gcvideo/tree/main/Firmware#diagnostics-mode
 
Technical Info
 
This design accepts the digital video output from the Nintendo Wii and uses ikorb’s GCVideo to output a high quality, configurable HDMI output to any HDMI compatible display! All AVE-HDMI units are sent with the latest stable release of GCVideo. Currently that version is 3.1.
 
The AVE-HDMI can easily be installed into any Wii (excluding the Wii Mini) using the on-board vias associated with the internal digital video and audio communications.

Unlike the original version of the AVE-HDMI, this product is a kit. This kit contains the AVE-HDMI, a 150mm long flex cable, and a mini-HDMI breakout board.  As of April 4th, 2023 all purchases of this kit will include an IR Sensor Board by default for Wii's that do not have a GameCube controller ports. This board can be installed in Wii's that do have GameCube controller ports, but it is not necessary.
 
This design can either be used directly as is or configured with the use of a universal remote or a GameCube controller. If you want to use a GameCube controller for configuration, then you can press L+R+X+Y and the configuration menu will open. GameCube controllers can only be used on Wii's that have GameCube controller inputs.
