About

Silent Hill is a 1999 survival horror game developed by Konami's Team Silent for the original PlayStation, following Harry Mason's search for his missing daughter in the town of Silent Hill; it has five possible endings depending on player choices. This is an in-progress, human-driven decompilation of the 1.1 US PlayStation release of Silent Hill, reconstructing C code from the original assembly across the main executable and multiple binary overlays covering engine, screen, and map logic. Reaching 100% match means every function has been accounted for, though further work on naming, data structuring, and documentation would still follow.

How it differs from the original

Unlike a typical remake or port, the project deliberately targets an exact, bit-for-bit reproduction of the original PS1 binary rather than changing or modernizing the game, and the team explicitly states it does not intend to produce a PC or other-platform port.

Known issues & limitations

• The project does not produce a port for PC or any other platform.

Additional notes

Scope note

The README states no AI-generated code has knowingly been used in the decompilation itself, though throwaway helper scripts made with AI were used for tooling.
