Instead, the project follows the “decomp + assets” model:

What made these ports revolutionary was the "Retro Engine." It did not emulate the original Genesis hardware. Instead, it reverse-engineered the game logic and assets, running them natively on modern devices. This allowed for:

The idea is to create a single launcher or "meta-game" that can load and switch between:

Creating a Sonic 3 RSDK is not a simple copy-paste job. The Retro Engine uses its own scripting language and scene format. Developers must: Sonic 3 Rsdk

is still in alpha. Playable demos exist for Angel Island Zone (Act 1 & 2) and Hydrocity Zone. Full completion — including all 14 zones, mini-bosses, and the Doomsday Zone — is estimated to be years away, if ever.
