From here it looks like all the video inputs just go through the same circuit on this chip, so that decreases my confidence that just switching to a different input will have any effect. I might try seeing if maybe I can hook my wii up to V2 in and seeing what happens. That said, this chip doesn’t…Read more

Since the signal out from the PC-98 is this weird 640×400 @ 24 kHz h-sync that nothing supports, the OSSC is the only thing I’ve found that can decode it into anything usable, so I don’t think I can find an adapter to use either. I can possibly replace the ADC…Read more

I’ve tested the cable and the PC-98, the red and green signals are definitely making it to the OSSC, and the test screen shows the normal grayscale gradient, but anything from the PC-98…Read more
