Thanks for pointing that Tweet out, very interesting.

I am thinking about just purchasing a NTSC-J Mega Drive and use the RGB bypass chip on that system, seeing as it’s mainly the PAL consoles that are being affected by these issues.

I’ve continued this thread on the OG forums, but wanted to share my current situation here in case people are having the same problems. Here’s a video of my current signal when connected through a proper Packapunch RGB cable directly to my TV (as the OSSC get’s NO SYNC):

Alright, I got the Packapunch cable and tested it on my OSSC. Still NO SYNC. When I plug the Packapunch directly into my TV’s SCART I get a continually, vertically scrolling screen (from bottom to top). So I guess it must have something to do with the CSYNC signal. I’ve yet to figure out how to fix it. Does someone know why I’m getting this result?

I’ve had to use Wayback Machine to double-check what my exact cable looked like, and I guess it indeed might not be compatible with upscalers/line doublers. Going to order a Packapunch cable before I’ll report back.

Thanks, I’ve completed the steps but now I get “NO SYNC” on my OSSC. I’ve double-checked all my work, including trace cuts. Here are two pictures of my work:

I’m not sure what I might have missed. I’m using a 2017 RetroGamingCables RGB cable (pre-packapunch) for the Model 1 but am unsure about the specification of this cable. I would assume these cables should be fine.
