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.

Mighty the Armadillo in Sonic the Hedgehog is a fan-made ROM hack for the Sega Genesis (Mega Drive), replacing the original Sonic sprite with Mighty the Armadillo from Sega's arcade platformer. It is not an official release but a popular mod created by the community, designed to run on original hardware or emulators. The hack was likely created in the early 2000s or later, though exact release details are not widely documented. The hack does not alter the core gameplay of Sonic the Hedgehog. You still guide the character through Green Hill Zone, Marble Zone, and other classic stages, collecting rings, defeating badniks, and reaching the goal posts. The only change is the protagonist's appearance and a few palette adjustments. The controls remain identical: run, jump, and spin dash. There are no new mechanics or level alterations. For fans of Mighty the Armadillo or early 90s platformer crossovers, this hack offers a novel way to replay Sonic's original adventure. It is a simple but effective sprite swap that feels fresh without breaking the game's flow. If you enjoy ROM hacks that experiment with character swaps, this is a fun, low-commitment curiosity worth trying.

How to play Mighty the Armadillo in Sonic the Hedgehog online

Getting Started

This hack is based on Sonic the Hedgehog, so the core gameplay loop is the same. Press Enter to start, then choose a save slot if prompted (none exist for this hack; it auto-starts). You control the character through each zone collecting rings, jumping on enemies to defeat them, and avoiding obstacles. The goal is to reach the end of each act before the ten-minute timer runs out.

Newcomers should know that rings act as a health buffer. Getting hit by an enemy or hazard scatters your rings, and if you have zero rings when hit, you lose a life. The spin dash (hold down and press the jump button) is your main speed tool. Special stages are accessed by collecting enough rings in a level, but the hack does not alter their design. Menus are in English since the base game is Western, so navigation is straightforward.

There are no new instructions specific to the hack. Just load the ROM in an emulator or flash cart and play. If you want a fresh visual twist on a classic, this is a quick way to experience Sonic's original adventure with a different character sprite.
