Recompiled Bloodborne (PS4) into a native library with static recompilation

The bloodborne-recomp project is a static recompiler designed to transform the Bloodborne PS4 executable into native code. By reading the game's x86-64 binary and writing functions as C, the tool enables the creation of a native library that the game loads during execution. This process removes the overhead associated with dynamic translation layers, which typically simulate PS4 system calls and GPU interactions. The recompiler handles approximately 99% of the game's functions, with the remaining code processed by a CPU translator. The project utilizes Claude Opus 5.5 to assist in naming functions, identifying object layouts, and documenting engine components such as render states and GPU address readers. While the recompiled code is architecture-agnostic, the game still requires a runtime environment to handle PS4-specific system calls and GPU commands. The project maintains a fuzz testing suite to verify instruction correctness against an interpreter. The recompiler does not distribute game code; instead, it provides a launcher that builds the library locally on the user's device using a trimmed LLVM toolchain.
