Sonic Game I Never Knew?

What's this? A Sonic game I've never seen before? _|￣|○ Failure! Anyway, SEGA made this for arcades and you play it with a track-ball. Controlling Sonic with a track-ball sounds super fun! And is that co-op play I see available!? Maybe if they hadn't given this the all too knock-off sounding name of SEGASONIC the Hedgehog it might have done better.
