    Pretty much, you solder the corresponding wires to the VGA pads on your screen.

    Dumb question but how does the VGA work with 480i? I ask for 240p forcing in virtual console games.

    The Wii will output 480i video, but then it depends on your screen if it supports it or not

    So I looked into doing this and didn't realise that the multiout pins luma and chroma are actually shared with RGB and Y Pb Pr.

    I noticed that pins 14-16 are marked as japan only for d-teminal cables, I'm pretty sure that those pins aren't connected for non JAP consoles.

    So the best way to add VGA with no external alterations seems altering cheap d-terminal cable to VGA.

    Wii motherboards are all the same, it doesn’t matter what region they are from

    Sorry, most write ups I found said that those pins are only used on Japan consoles.

    Would anyone have a link to the sanded layer scans that came out a couple of years ago? I've tried searching them but have not been able to find them. Optimally I can remove a resistor or capacitor to disconnect those pins from the d-terminal lines.

    It seems R56 and R58 can be removed to isolate pins 14 and 16 of the multiout. Clean VGA mod is now theoretically possible.

    Yeah that should work. R56 and R58 are simple pulldown resistors, since it seems like the Wii only handles the D-Terminal data line 2, while the others are always pulled to GND.

    It works for the most part but I seem to be having some video issues...

    Any text has a weird haze/shading, and the right side of the screen is glitched and just stretches the image and not sure how to fix that and was wondering if any of you had a solution. Overall great though, thank you @Aurelio !

    @thedrew Im not aurelio, but are your R, G and B lines' wires shielded? It may just be interference.

    It’s not interference. You haven’t set 480p in the system menu, right?

    Actually, they are not shielded. But I've seen interference before and it usually doesn't look like this :/

    I have previously, but then later restored the wii to start fresh with softmodding it... but come to think of it, do you think restoring cleared some config files for previously setting it to 480p?

    Yeah you probably lost the configuration. I will release an homebrew to enable the 480p even if has never been selected before
