Yes I guess so, whatever it is the videos show it pretty clearly. Any ideas?
Edit: Figured it out it was because 5x res was set to 1920×1080 both 1920×1200 and 1600×1200 don’t have the issue on my 4K TV. I’ll just use 1920×1200 as the 1600 stretches it and I don’t like that.

April 28, 2018 at 7:11 AM in reply to: Bad audio quality through SCART from Genesis (using headphone out) – OSSC 1.6 #21212I had buzzing and audio distortion of all sorts literally making my Genesis unplayable until I bought a quality properly shielded RGB SCART cable the one you linked to is almost definitely the same crappy China made one I had issues with that I bought off eBay for a similar price. The good one I got in the mail just today is a packapunch cable from retro gaming cables. My money is that is your issue. I even bought new old stock replacement power supply as I had read that could be the problem but was proven wrong when I tested it out with no change. Flawless through the good SCART cable now though!
Ah cool it is on single player Sonic 2 I saw that with. Turns out the hissing didn’t go away just was less noticeable from moving the jack. I googled it and it turns out the person who sold this Genesis 1 sold it with an SA-160A power supply that’s for Mega Drive 1’s and has different specs. IFixit has a thread where people report the wrong power supply will cause the buzzing. So I’ll get a proper power supply soon to see if that resolves it, if not I’ll do the audio mod on my Genesis and I’m pretty sure that will do the trick. Cheers!
Jiggling the cord got rid of it so I’m pretty sure it’s the headphone jack now. There’s a minor “jiggling” of image on certain parts of the screen (varies location) like on Sonic 2 I paused the game and looked close as the Score / Time in the top left was distorted and when I looked up closer it was bouncing the image back and forth ever so slightly in the one spot, everything else on the screen looks clean with none of thise jiggling, found a few examples of this but it always seems to be in just one spot on the screen. Is this also more likely a badly shielded SCART cable or am I correct in thinking capacitors may be the root problem so replacing them may resolve the picture jiggling?
Is someone able to post pictures of what the completed pin 155 fix by Borti looks like? I’ll be modding my SNES Mini soon so that would be helpful.
