Idk if i would use that term, but I am capturing screen data into FPGA's SDRAM and scaling an image output.

At this time I can serialize audio into the video stream. Sometimes tomorrow Ill get controller working and might dig around for capture card.

After finding audio board and fixing backwards clock buffer (this broke a PCM and a buffer), and fixing FMT0 and FMT1 resistors to pullups, I got digital audio into the FPGA. Then I had to make an async fifo that was 48 wide for my PCM words.
Again, this took several hours for me to realize this.

So I re-implemented the hsync vsync de generation organically in the softcore but still generate coordinates externally. The hdmi softcore was broken for hours when it was supposed to carry valid audio.

I will order new board in a few weeks that is better with EMI and SI and shorten bridge FFC. Ill also begin designing the other subcarrier boards for other handhelds. If theres anything you want me to support let me know in comments please. Ill go buy one of them and study it.
