About this game

Sonic Debut is a ROM hack of the original Sonic the Hedgehog for the Sega Genesis. The project reimagines the game by integrating prototype and concept material from Sonic's early development rather than aiming for a retail-accurate remake. It features significant mechanical shifts, such as replacing the traditional ring-based health system with a Hit Point (HP) counter and requiring a double-tap of the jump button to enter a rolling state.
