Sonic The Hedgehog 2 With Sonic 1 Sprites (New Years Build) (Genesis) Romhack

Happy New Years everyone! Here’s hoping 2026 turns out better than 2025!

This is Sonic The Hedgehog 2 with Sonic The Hedgehog 1 sprites! This current release only features Sonic 1 styled sprites for Sonic, Eggman, the life icon, and the goalposts. Future updates will include full-on Sonic 1 sprites for things like checkpoints, monitors, spikes, etc. Yes, a beta version of this was once release, but however it was never fully finished. This is the only finished build of the hack. Hope you all enjoy! Hack by T-Bone.
