Unofficial ROM hack. The notes below come from community sources and have not been verified against the patch itself, so levels, mechanics and features may differ from what is described.

This is Sonic The Hedgehog 2 RMS Edition V0.3, a fan-made ROM hack of the classic SEGA Genesis platformer. It's an early build of a mod that reworks the original Sonic 2 experience, though exact changes aren't widely documented. As a hobbyist project, it's meant for players who want to see an alternate take on the blue blur's second 16-bit outing, running on the same hardware that defined 90s side-scrolling action.

How to play Sonic The Hedgehog 2 RMS Edition V0.3 online

Getting Started

Start the game by pressing Enter. You'll see an open plains zone with loops and enemies. Hold right on the Arrow Keys and tap X to jump over pits or onto badniks. Collect rings to survive hits: if you get hit with rings they scatter, but with zero rings you lose a life.

Progress through each act by reaching the giant signpost at the end. The core loop is running, jumping, and rolling into enemies at high speed. Each zone has different obstacles and subsurface layers. If this mod introduces new level layouts or enemy placements, explore carefully since you can't rely on stock Sonic 2 knowledge alone.

Press S while running to do a spin dash - hold down then tap X to charge and release. Use this to break through corners and gain momentum. If the mod adds any custom mechanics, they're not documented here, so test each button and observe patterns.
