Sonic 3: D.A. Garden Edition is a ROM hack of Sonic 3 & Knuckles created by D.A. Garden. It aims to be a "vanilla" but complete and fully featured take on S3K, with 23 acts of new level layouts matching the scope and size of the original game. In 2020, a user named Thorn ported the hack to the Sonic 3 AIR project as a mod, allowing it to be played with the additional features AIR provides.
