ROM Hack
5· 0 votes

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 a ROM hack of Sonic the Hedgehog for the Sega Genesis, created by fans. It replaces Sonic with Kirby, bringing the pink puffball into Green Hill Zone and beyond. The exact release date is not documented, but it was likely made in the early 2000s. It is a fan-made modification, not an official release. You control Kirby through the same levels as Sonic 1. Instead of Sonic's spin dash and ring collection, Kirby uses his float ability to glide across gaps and inhales enemies to copy their powers. The goal remains reaching the end of each zone. The hack keeps the original level layouts but changes the protagonist. This hack is a fun novelty for anyone curious about crossover twists on classic games. It does not add new levels or major changes, so it is a quick playthrough. For Kirby fans, seeing him in Sonic's world is the main draw. It is a niche item in the Genesis hacking scene.
