🎮 Play Sonic the Hedgehog 2 (World) (Beta) (Simon Wai) [Hack by Esrael v0.23] (~Sonic 2 Delta) Online (Sega Genesis)

Sonic 2 Delta is an ambitious Sega Genesis ROM hack created by Esrael, built upon the legendary Simon Wai beta prototype of Sonic the Hedgehog 2. Rather than creating entirely new levels, this hack focuses on restoring and completing the scrapped content from Sonic 2’s development cycle. Players can experience fully playable versions of legendary lost stages like Hidden Palace Zone, Wood Zone, and Dust Hill Zone, seamlessly integrated into the standard level progression alongside the familiar retail zones.

How to Play

The objective remains true to the classic Sonic formula: race to the end of each act, collect rings to survive enemy hits, and defeat Dr. Robotnik’s badniks. The default Sega Genesis controls apply in your browser: use the arrow keys for movement, and press Z, X, or C to jump and perform your spin attack. Pressing down while moving lets you roll, and holding down and pressing jump revs up your Spin Dash.

Tips

• Explore the restored zones carefully; their layouts incorporate elements and gimmicks that didn’t make it into the final version of Sonic 2.
• Since this hack restores beta elements, some object placements and boss mechanics might differ slightly from the retail game, so stay on your toes even in familiar zones.
