SILENT HILL DECOMPILATION PROJECT

An in-progress decompilation of the 1.1 US release of Silent Hill on the Playstation 1.

Progress

Due to the limited memory on the PlayStation 1, games often distribute their logic and functionality across different binary overlays. Silent Hill follows this approach by separating core engine code, some screen-related code, and map stage logic code into many distinct binaries. The main executable (SLUS_007.07 on the 1.1 NTSC release) serves primarily as a memory handler.
