Someone has just posted a project on github that allows HDMI output from a launch model Wii via GCVideo. The project is focused on cost, so it’s HDMI-only and there’s no flex-cable requiring a manual installation.
The creator says they’ve spent several hours testing it on my launch-model Wii and now would like other people’s feedback. Check out the project here: https://github.com/wmi-0/wiihdmi
If you’re wondering how this is different from the Wii Dual HDMI kit designed by Dan aka citrus3000psi, his supports RVL-CPU-40, -60, K01 and K02 revision Wii’s, none of which are the original launch model. While Dan won’t be officially supporting any launch models, last year he posted a design that showed the potential of it happening. I’m glad to see someone else step up and make it happen!
