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.

Sonic 1 Redux is a ROM hack of the original Sonic the Hedgehog for the SEGA Genesis. It's a fan-made modification that enhances the classic 1991 platformer with quality-of-life improvements and new features. The exact creator and release date are not widely documented, but it's been available online for years as a popular way to experience Sonic 1 with modern tweaks. The core gameplay remains identical to the original: you control Sonic as he races through Green Hill Zone, Marble Zone, and beyond, collecting rings and defeating Dr. Robotnik. What Redux changes are the additions: the spin dash from Sonic 2 is implemented, allowing you to charge up and blast forward. Tails also makes an appearance as a second character option. The physics and level layouts stay true to the 16-bit original, so veterans will feel right at home. For longtime fans, Sonic 1 Redux offers a polished way to revisit the game that started it all. The inclusion of the spin dash alone makes it more playable for those used to the later entries. If you love Sonic 1 but wish it had the mobility of its sequels, this hack is worth checking out. Just know it's a simple enhancement, not a full conversion.

How to play Sonic 1 Redux online

Begin by pressing Enter at the title screen to start a new game. The goal is to reach the end of each act by running right, jumping over pits, and defeating enemies by rolling into them. Collect rings to protect yourself from damage, and grab 100 for an extra life. The Redux hack adds the ability to perform a spin dash by holding down on the D-Pad and pressing the jump button (X) to charge, then releasing to blast forward. If you choose to play as Tails, you can press the jump button again while in the air to fly briefly, which helps reach higher platforms. There is no save feature, so you must finish the game in one sitting or use the level select code (hold A, B, and C at the title screen and press Start, though this may vary in emulators). Take it zone by zone and watch out for spikes - they'll kill you instantly.
