It synthesizes data salvaged from famous Sega leaks, including the iconic , Sonic 3C build 0408 , and build 0517 . The "v1.1 Update" refines these elements, addressing game-breaking bugs, adding tailored special modes, and stabilizing the gameplay loop.

The primary goal of the project is to achieve absolute historical accuracy. Rather than inventing new features, the project restores forgotten layout logic, early graphics, and authentic prototype programming.
The Sonic 3C Delta 11 prototype is a critical piece of the puzzle that explains the "Lock-On Technology." It captures the raw ambition of Sonic Team—a team that had built enough content for two games but had to engineer a software solution to deliver it to players. For anyone interested in game development, playing Delta 11 is like looking over the shoulder of a programmer in May 1994, watching history being written in code.
