Sonic 1 - Galaxy Edition is a ROM hack of Sonic the Hedgehog for Sega Genesis, likely featuring a graphical overhaul and perhaps new level designs inspired by space and cosmic themes, hinted by its name. The core gameplay of fast-paced platforming and ring collection likely remains from the original Sonic 1. This modification, being fan-made, is not an official Sega release.
