Engine

The package's engine is DarkIzuku/bloodborne_pc at tag v0.4.0-darkizuku-preview.1, built for Windows with two changes:

• windows-frame-rate.patch – lifts the Windows-only 30 / 60 / 90 limit in gpu/shim/core/emulator_settings.h, so 120, 144 and uncapped work as they do on Linux.
• run-windows-frame-rate.patch – lets scripts/run_windows.py pass those rates on (the uncapped patch with the sprint fix, plus the frame limiter).

Build

In the MSYS2 CLANG64 shell (packages as in the engine's README):

git clone --branch v0.4.0-darkizuku-preview.1 --recurse-submodules https://github.com/DarkIzuku/bloodborne_pc
cd bloodborne_pc
git apply /path/to/windows-frame-rate.patch /path/to/run-windows-frame-rate.patch
cp /path/to/win_compat.h gpu/
CFLAGS="-Wno-error=unused-but-set-global" CXXFLAGS="-include $PWD/gpu/win_compat.h" bash build.sh

win_compat.h supplies headers the bundled FSR 3 SDK expects transitively, which newer libc++ no longer includes. The result is out/bb-probe.exe; the package's out/ holds it with the CLANG64 DLLs it loads.

GPL-3.0-or-later, like the engine.
