how to build the super mario 64 pc port

# Before Building
* get the sm64 US rom in z64 format, rename to baserom.us.z64 and put it
  in the sm64pc root folder
* you can also use the japanese rom (except rename to .jp instead of .us)
  and when you run make you would pass VERSION=jp

# Building on Linux

* install gcc make glfw-devel libusb-devel audiofile-devel

  make -j9 TARGET_N64=0

# Building on Windows

* install msys2 and start it

  pacman -Syu

* restart msys2

  explorer .

* copy sm64pc source code folder to the directory that opens in explorer

NOTE: in these commands when you see -j9 replace that with the number of
cores/threads to use when compiling (in my case 9)

  pacman -Syu
  pacman -S git make auto{make,conf} libtool python3 gcc \
    mingw-w64-x86_64-gcc mingw-w64-x86_64-SDL2 mingw-w64-pkg-config

  cd sm64pc

  git clone https://github.com/mpruett/audiofile/ --depth=1
  cd audiofile
  CC=x86_64-pc-msys-gcc CXX=x86_64-pc-msys-g++ ./autogen.sh --prefix=/usr/
  cd libaudiofile
  make -j9
  make install
  cd ../..

  make -C tools clean
  make -C tools CC=x86_64-pc-msys-gcc CXX=x86_64-pc-msys-g++
  make -j9 TARGET_N64=0
