I was wondering, does anyone know what model Mega Drive/Genesis is the best model of there, for both systems? I know that typically Model 1 systems have the best audio quality, however I've also heard model 1, model 2 and model 3 systems have different video encoder chips. Does that only apply to the Genesis where video is being converted into composite? What about the Mega Drive which is running RGB? We're wanting to try and get the best out of the system and trying to figure out which is the best way to go. Superior audio AND video quality is preferred but it seems for NA at least compromises are being made somewhere as the systems lifespan went on.
