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.

Shadow the Hedgehog in Sonic the Hedgehog is a fan-made ROM hack for the SEGA Genesis. It replaces Sonic's sprite with Shadow from Sonic Adventure, while keeping the original level design and mechanics of the first Sonic the Hedgehog game. The exact release date and creator are not widely documented, but the hack circulated online in fan communities during the early 2000s. This is not an official Sega release, but a mod built on top of the classic 1991 platformer. You play as Shadow, running through Green Hill Zone, Marble Zone, and other classic stages with the same physics and ring collection mechanics. The core loop remains identical to Sonic: accelerate, jump on enemies, collect rings, and reach the goal ring. Shadow retains Sonic's spin jump and speed, so the gameplay does not change beyond the visual swap. There are no new levels or story elements added. This hack is worth trying if you are curious how Shadow would look and feel in the classic Sonic style. It is a simple sprite replacement, not an overhaul, so do not expect new content or altered gameplay. Compared to more elaborate hacks, it is a minor tweak that demonstrates the community's lasting interest in character swaps. It is best suited for fans who want a quick, nostalgic peek at an alternate universe version of the original game.

How to play Shadow the Hedgehog in Sonic the Hedgehog online

Getting Started: Load the ROM into your emulator and press Enter to start. You will control Shadow through the same six zones as the original Sonic. Use Arrow Keys to move, X to jump, and hold S while moving to build up a spin dash. The goal is to collect rings for protection, avoid enemies and spikes, and reach the end of each act. Defeat Dr. Robotnik at the end of each zone to proceed. The menus are in English, so navigation is straightforward. The game saves no progress; you must finish in one sitting. Remember that rings do not grant extra lives - you start with three lives. If you die, you restart from the beginning of the act. This hack is identical to the original game except for Shadow's sprite.
