This is a ROM hack of the original Sonic the Hedgehog for the SEGA Genesis, titled Sonic the Hedgehog Plus. It was created by a hacker known as Hivebrain and released as version 0.20. The hack modifies the classic 1991 platformer, but the exact changes are not widely documented; it likely offers tweaks to level layouts, physics, or other gameplay elements while keeping the core experience intact. This is a fan-made mod, not an official release, and it runs on the same platform as the original.

How to Play Sonic the Hedgehog (USA, Europe) [Hack by Hivebrain v0.20] (~Sonic the Hedgehog Plus) Online

Getting Started: Launch the game and press Enter to start. You control Sonic the Hedgehog, a speedy blue hedgehog. Your goal is to reach the end of each level, called a Zone, while collecting rings, avoiding obstacles, and defeating enemies like the iconic Badniks. The core loop is simple: run from left to right, jump over spikes and pits, and use the spin attack (press S or X) to destroy enemies. Rings protect you from damage; if you get hit while carrying rings, they scatter and you survive. If you have zero rings and get hit, you lose a life. At the end of each Zone, you face Dr. Eggman in a boss fight. There is no save feature, so you must complete the game in one sitting or use a password system if the hack includes one. Fans of the original will find the controls and mechanics familiar; the hack may introduce subtle changes, so experiment as you play.
