Sonic 1 Swift

Sonic 1 Swift is a ROM hack of the original Sonic the Hedgehog for the Sega Genesis. We know many of you enjoy classic Sonic hacks at Y9FreeGames, so we decided to include this game in our collection. I tried this hack myself, and the first thing I noticed is how different the levels are compared to the original. The layouts are sharper, the music for each Zone is unique, and even the enemies look new with custom sprites. It gives you a new experience while holding the charm of the classic Sonic title.
