Apologies if i'm mistaken, but can't the ADV7125 DAC add sync to any channel? At least thats what it looks like from the datasheet

The description of the /SYNC pin only mentions the green output: "Composite Sync Control Input (TTL Compatible). A Logic 0 on the SYNC input switches off a 40 IRE current source. This is internally connected to the IOG analog output."

Ah well, thats explain it. Guess there really wasn't any good option to match the original Wii YPbPr/RGB pinout whilst still supporting RGsB.
Thanks for putting up with my questions citrus3000psi and Unseen :)

Thank you all for the detailed explanations. Looks like we won't be having a cable change.

I've compiled the wiidual 1.1 3.0d with the commit changes that swap the channels back.

This is identical the master branch btw.

Anyone interested in a Wii to VGA adapter?

I have a few prototype boards ill order soon, these will be perfect for using with VGA to BNC cables for broadcast monitors or BNC matrix/switches or VGA Extron matrix systems.
Has a 3.5mm jack for audio output.

I missed the boat on the Wiidual. Will it be making a comeback production or is it done with its lifetime run?
