To understand RSDKv3, you must understand the "Taxman" legacy. In 2011, Christian Whitehead demonstrated a proof-of-concept: a perfect recreation of Sonic CD ’s physics running at 60FPS. Sega took notice. They licensed his engine for an official remaster of Sonic CD (2011).

The project is a comprehensive decompilation of the Retro Engine v3, the proprietary engine developed by Christian Whitehead for the 2011 remake of Sonic CD . While the engine originally powered the game on platforms like Steam and mobile, the RSDKv3 decompilation allows fans to run Sonic CD with enhanced features, mod support, and better performance on modern Android devices.
