What’s the real difference between RGB SCART and composite on the Sega Genesis?

[John.W]

I just got a CRT TV for my old consoles, and I'm trying to get the best picture from my Sega Genesis. I’ve read about using the original RGB SCART cable, but my set only has composite and S-Video inputs. Is the jump in quality from composite to S-Video really that noticeable for 16-bit games, or am I overthinking it?

I did a side by side with a CRT using composite and then S-Video when I had a spare lead. The difference was noticeable—colors looked crisper, less color bleeding, and edges felt a touch sharper on most 16-bit games.

Some folks chase RGB SCART as the holy grail, but if your TV only has composite and S-Video inputs, you’re already in a practical space. For a Genesis, the jump from composite to S-Video on a CRT is noticeable but not life changing; you’ll mainly see cleaner color separation and a bit less blurring.

Do you actually notice the difference, or is it one of those things you worry about more than it matters when you’re in the thick of a game?

I once tried a cheap RCA to S-Video adapter and the picture looked cleaner, but the setup was fiddly and the extra cable kept pulling the plug; I ended up sticking with composite because it was stable and the CRT’s native scanlines did most of the work anyway.
