I decided to bring out my SFC after a couple of years on the shelf and booted up fine but the picture is noisy and I don't remember it was there last time i had it on. Is it about to give up on me or can it be something else in the chain?
Here's a video where i tried to capture it, but it was not easy to use filming the TV

It's connected with a Universal Nintendo PACKAPUNCH RGB SCART cable into the OSSC.
I also have a Mega Drive 1 that I bought last week. It got the jailbars (will probably try to mod it later) but it's not "moving noise" in the same that SFC got.
