that game rocks, I ususally post over at mustangworld.com, and someone there said they were playing it while postering. He said for $5 he would make me a copy and mail it to me but I was trying to find it for free, haha
I have tried, and DLed a few of them, one was mexican and didnt work, one is like a whole arcade thing that doesnt actually have sonic, and the other one flashed to the dos prompt but than vanished. I wanna play that game soo bad
