It's been a while, so it's time for an update! Previously I started to integrate a different HDMI encoder; I made some progress with this but didn't get it fully working and I ran out of steam. After coming back to this project a while later, it transpires that Zwenergy had swapped out the HDMI encoder used by gbaHD to an external one and by the looks of it, the one I was trying to use!

I'm really happy with this at it saves me the effort, although unfortunately it still isn't fully compatible with my TV - again the horizontal positioning doesn't sync and there is no sound. As better compatibility is claimed, I tried something that didn't work before - hooking it up to a HDMI converter.

I recently got a CRT TV and I'm using a basic HDMI to composite converter with it, so I tried it with that. Et voila - we have video and sound! The aspect ratio is wrong as gbaHD output is 16:9 and the TV is 4:3; I'm planning to re-fork gbaHD and synthesise a version with a 4:3 ratio.

Of course, this kind of defeats the point of having HDMI output when there are other options. It still gives me the ability to use other adaptors - I have a HDMI to VGA adapter to test too - and if gbaHD is developed further then compatibility with my awkward TV may still happen!
