Shenmue 3 won't be the same unless xbox has a dreamcast quailty vga box. Because most people here probally played Shenmue 1 and 2 on vga. I know I did.

Plus the old fact that most people don't consider:
We don't even have a 100% perfect (and legal) Genesis emulator on Dreamcast yet.

Yeah but it would be easier to emulate for Sega CD since there would be no hardware to emulate because the Genesis is already their.

Why not make a Sega Genesis emulator for Sega CD. Since the Genesis and Sega CD are attached I think it would be possible.
