Sonic the Hedgehog OmoChao Edition
About the Game
Sonic the Hedgehog OmoChao Edition is a fan-made ROM hack of Sonic the Hedgehog for the Sega Genesis / Mega Drive. The hack replaces Sonic with OmoChao, the floating robot guide that first appeared in Sonic Adventure 2. The original stages, enemies, and story remain intact, while the main visual change is the playable character.
This is an unofficial project created by the Sonic fan community and is not an official release from Sega.
๐ค Play as OmoChao
The most noticeable feature of this hack is the character replacement.
Instead of controlling Sonic, you play through the original adventure as OmoChao. The character uses custom sprites while following the same movement mechanics as Sonic in the original Genesis game.
The hack focuses on presentation rather than introducing new gameplay systems.
๐ด The Original Sonic Adventure
The complete Sonic the Hedgehog campaign remains unchanged.
You travel through the familiar zones:
- Green Hill Zone
- Marble Zone
- Spring Yard Zone
- Labyrinth Zone
- Star Light Zone
- Scrap Brain Zone
- Final Zone
Your objective is still to stop Dr. Robotnik and rescue the animals trapped inside Badniks.
โก Classic Gameplay
Although OmoChao replaces Sonic visually, the gameplay stays faithful to the 1991 release.
You still:
- Run through side-scrolling stages
- Jump on enemies
- Collect rings
- Search for hidden paths
- Enter Special Stages
- Collect Chaos Emeralds
- Defeat Dr. Robotnik
Anyone familiar with Sonic the Hedgehog can begin playing immediately.
๐จ A Character Swap ROM Hack
OmoChao Edition belongs to a group of Sonic ROM hacks that focus on replacing the playable character instead of redesigning the game.
The hack keeps:
- Original level layouts
- Original enemy placement
- Original boss battles
- Original progression
The primary change is OmoChao's custom sprite replacing Sonic throughout the adventure.
