Sonic 1: Back 2 The Future is a ROM hack of Sonic the Hedgehog where you play through alternate versions of classic zones, redesigned with a futuristic twist. You control Sonic through modified acts of Green Hill, Marble, and Labyrinth zones with changes to layouts, color palettes, and enemy placement that shift the flow of gameplay. The hack keeps the original physics but introduces new level paths and sprite adjustments, creating an experience that mirrors time travel within the same engine. Your goal remains to collect rings, defeat Dr. Robotnik, and reach the end of each stage with precision.
