Clean-Room Reimplementation
A technique in which a compatible replacement library or system is reconstructed through reverse engineering without using the original source code, producing a binary-interface-compatible alternative that allows host programs to run normally. It is commonly employed in legacy game porting and cross-platform compatibility projects.

The work of reimplementing a DLL with interfaces and behavior consistent with the original is known as "compatible reimplementation" in the field of legacy game preservation and porting
The difficulty of compatible reimplementation lies not in reproducing individual functions, but in ensuring behavioral equivalence across all host call paths, including boundary values, memory layout, error handling, and even the reproduction of undefined behavior
