Speaking of Sonic the Hedgehog 2, that game also doesn't seem to have an article here. I'd highly suggest making one for that game as well, as there's ton of beta content that never made it into the Genesis orginal.

This site is pretty useful for this sort of stuff, and also has a bit of info on the Sonic Adventure beta as well.
