Blast processing! It's not a lie, it's real dammit! It's real!No, the Sonic titles could not have been done on the Super Nintendo.
You have to keep in mind, 'Sonic the Hedgehog' was designed from the very beginning to take advantage of the strengths of the Genesis system. Sega knew that the SNES lacked processing power, so they took the one area where the Genesis had Nintendo's console beat and exploited it and turned it into a marketing campaign.
It's real. :'(
