In this first part of a two video series I C-Sync Mod a Sega Mega Drive for the best picture possible using an RGB Scart cable for the Sega Mega Drive.

I explain why you can't wire pin 7 (Sync) of the Mega Drive's Video AV Out DIN socket directly to a standard TV input over RGB Scart and I'll show a alternative place you can get C-Sync from.

I'll also show a before and after video showing the advantages of C-Sync for Sync compared to the more commonly used Composite Video for Sync and we'll finally eliminate the infamous Sega Mega Drive Jail Bars (ZigZag) vertical lines.
