Sonic 3 Modgen Edition

Sonic 3 Modgen Edition is a fan-modified version of Sonic the Hedgehog 3 rebuilt to operate on the ModGen engine for improved emulator performance and more precise in-game behavior. You can control Sonic, Tails, or Knuckles through zones like Angel Island, Marble Garden, and Ice Cap with consistent frame timing and refined collision detection. This version preserves the original level design while enhancing physics synchronization, animation fluidity, and special stage responsiveness. The ModGen engine allows you to experience smoother transitions between acts and more accurate mechanics without altering the core structure of the game.
