So I have finished the DAC card. It will convert YUV422, YUV444 and RGB colorspace digital video sources into analog video. The IC works with misterFPGA and direct video mode. It also works with the video from my scaler board. It will be sent to get made at same time as digital video board

NGPC update: It seems when you tear out the timing module from HDMI softcore, you may misalign everything when generating audio. ....

Shielded flex helps. I think washed out color is electrical issue...

Two very minor misalignments here but I mostly have it nailed.

I have since fixed the first scanline being messed up. It turns out issuing 3 instructions in 1 cycle depending on each other made the BRAM select double toggle. All thats left is fixing the initial garbage values popping out. Suspect SDRAM misses personally...

1/2 2026 going to be lit 🔥 Framebuffer project totally works and this is NGPC working in 1440x240. NGPC must be triple buffered because the clocks turn off in blanking just like GBC, GBA, and launch model DS. Will test 640x480 at some point today, but fairly confident it will take less than 1 hr.

Its a signal integrity nightmare but ironically works. Verified pixel accumulator logic and frame indexing/arbiting. Will have purpose built PCB in a few weeks for NGPC interfacing so this wiring nightmare go away

It seems write ptr is inaccurate and also miss writing one entire screen to region; duplicate data from only 1 screen is written to sdram. So readout is distorted.
