Thought it would be helpful to identify the pins/wire colours..
The orange wire is the one added to carry 5v
Black is as expected GND
Green is Green out
Blue is blue out
Yellow is Red out ..
The Red and white wires are Right and left Audio.

mate it should be schematic when doing things like that, not just pictures.

You're right of course ..
..and I was working on it when you posted ...🤣
Anyway ..this is the schematic I came up with

keep in mind if you use a premade RGB lead ..all the relevant ground connections are already linked inside the Xbox plug end ..which makes the job easier..

Dang, all that work and the end result is STILL so blurry. (Maybe can you put up a better-focused pic for that last one?)

Not at the moment sadly ..my camera is refusing to work correctly in anything but macro mode..
maybe later..

Bummer about the camera 🙁

A real nice closeup of an area with fine detail might help us see how it looks. Of course, there will be the moiré pattern but I think it might still be informative.

Borrowed a camera ..and took a few snaps of a ghibli movie ) running in 720p on XBMC..
sadly I havent worked out how to turn off the flash ..
I dont haveany Xbox games that output and run in 720p ..such as 'the matrix' so only can output games in a lower resolution ..
Hope these photos give some idea anyway..

It would appear I can also output the same movie in 1080i through XBMC ...but for some reason the audio isn't sent via HDMI ?
could be a setting in XBMC ..but I rather suspect the this might be the Wii dongle ?
There is 3.5mm jack on the Wii dongle which allows the audio to be output to external speakers..
I'll keep working on it ..
All that said You can still connect an Xbox to a modern TV via hdmi with audio to play Xbox games ..which is why I started this project ..anything else is just bonus.

Interesting. I never would've thought someone would try to make an (original) XBOX HDMI adapter. Since HDMI adapters exist for every other 6th generation console, I figured it'd be time for the original XBOX to receive the same treatment.

Some TVs will allow you to use the RCA/Composite audio jacks for separate analog audio in for HDMI since there are some devices that pass DVI video through HDMI when using an adapter, but since audio isn't carried through DVI, a separate audio connection is expected for those devices. My first instinct would be to try using a 3.5mm to RCA cable to connect your adapter's audio feed to the TV.

There are a handful of XBOX games that support outputting in HD (mainly titles from 2002-06).

In actual fact a company called Pound I think did make such an adapter a few years back ..but these are getting more difficult to find ..and I suspect aren't made any loger since the price for these has doubled if not trebled.
hence my reason for trying to come up with a cheap solution.
There is no upscaling involved ..on account most TVs take care of this internally ..
The device is simply format change and pass through.
After doing some reading..
The audio issue was also present on the 'pound' unit ..
It would appear some LCDs either dont process the hdmi audio ..or is more likely muted if not what was expected.
In fact ..some TVs will not even process and upscale the lower res signals from the Xbox via hdmi ..resulting in a blank screen ..
switch on 720p and 1080i ..and use a higher res game in the Xbox ..and the blanking problem goes away..
not sure about the audio issues.

I have ordered a cheap copy of 'the matrix' xbox game which does 1080i ..to do some tests.
certainly I cant get this homebrew adapter to output anything at lower res ..on my LG 4K Tv ..but it passes video just fine on a cheapo Toshiba HD TV ..
