A implementation of the N64 RSP for emulators. Used in Mupen64Plus and in Parallel emulators, this version is a Zilmar-spec plugin, which means its made for Project64 or other Zilmar plugin based emulators.
To build it, install MSYS2 and its Toolchain package (pacman -S mingw-w64-i686-toolchain && pacman -S mingw-w64-x86_64-toolchain) then run build_win.sh to build it for your OS.
Make sure to always build both x86 and x64 versions depending on which architecture of the emulator you're running.
