I have a grey Super CDROM2 and Core Grafx II unit. I'd like to RGB mod them. However, From my experience I always get audio buzzing when using scart cables with other RGB systems. Shielded cables help but the buzz is still noticeable while wearing headphones so I usually try to separate the audio by adding separate audio jacks or other methods.
Can I do the RGB mod on the core grafx II unit itself and run a cable from the core grafx II to my monitor and run a cable from the super cdrom2's av output to my stereo? I'm hoping if I do the mod this way there wouldn't be any buzzing since the signals aren't travelling together in the same cable.
