Sega has just released an iPhone version of their classic Sonic the Hedgehog, the game plays just like the original did on the Mega Drive.
The iPhone version can be played in classic mode with a smaller game screen within the iPhone screen, this uses the original resolution or a stretched mode with the game playing full screen on the iPhone.
Check out the video of it in action below.
Sonic The Hedgehog for the iPhone is available now for $5.99 from iTunes.
