bloodborne_pc

deadinside28/bloodborne_pc · ★ 3.2K

bbport is a native Linux port of Bloodborne (CUSA03173, v1.09) that runs the original PS4 executable directly on an x86-64 Linux PC. It isn't a general emulator — the game's own code executes natively, a small custom runtime replaces the PS4 system libraries, and a Vulkan renderer derived from shadPS4 handles the GPU side, including temporal upscaling with FSR 3.1/4/4.1.1.
