I’m having similar issues to another user on this forum with a Magewell device and NES Capture through the OSSC. The top 15% of the screen begins to flash with black and white lines, and this only seems to happen with the NES, and not with the SNES.
No issues capturing using Blackmagic or Micomsoft cards, but would like to get this working on the Magewell. There doesn’t seem to be any option on the Magewell to allow higher input bandwidth, but I would think the signal could be cleaned up somehow on the OSSC end to handle this case?
Again, SNES seems to work just fine. I’d be grateful for any suggestions.
