Aonic brings Sonic’s Green Hill Zone to the Amiga 1200
REASSEMBLER has released the first public playable demo of Aonic, an ambitious attempt to bring the original Sonic the Hedgehog experience to the Commodore Amiga. The current build recreates Green Hill Zone Act 1 and targets PAL Amigas with the AGA chipset and just 2 MB of Chip RAM, making a stock Amiga 1200 the project’s main reference system.
Rather than simply creating a Sonic-inspired platformer, Aonic adapts code, game logic and data from the original Mega Drive version while heavily reworking the rendering system for the very different Amiga hardware. The aim is to preserve Sonic’s familiar physics, momentum and speed as closely as possible.
The demo became publicly available on itch.io on 31 August 2026 under a name-your-own-price model and remains a work in progress. REASSEMBLER has also discussed eventually investigating an Amiga 500 version, although finishing the AGA release comes first.
