So in August I got a Genesis. High Definition graphics model, extension port in the back. Only 1 minor scratch I'll remove eventually. It seems like I have a year 1 Genesis. A friend told me if booting it up it says "By or under license from Sega Enterprises LTD" it's one of the first. Mine does say it. If this is from the mythucam first batch is there any advtanage I have vs a later Model 1 or a Model 2?
