I'm assuming it would play in a tunnel like thing using the clickwheel to move side to side to collect rings?
Just a reminder that if y'all have a PC or Mac made in the last 5 years, you can run the game natively (as in, the exact game as it came on the Genesis) via emulators. Just yesterday, I downloaded a Genesis emulator and Sonic, because I wanted to play it on my Macbook. It's become somewhat of a tradition during finals week :^)
Yea people have known about desktop emulators for years now... nothing new.
