Pluto does not contain a built-in asset extractor and must be compiled from source code, like many other SM64 PC ports.

You will need to obtain an unmodified, vanilla US ROM of Super Mario 64.

---

Download and install the latest version of MSYS2.

Launch the MINGW64 executable (MINGW32/32-bit is untested). If you can’t find it, search MINGW in the start menu and select the app with the blue icon.

Enter pacman -Syuu in the prompt and hit enter. Press Y whenever it asks you to update packages.

Next run this command in the terminal to install our necessary packages:

pacman -S unzip make git mingw-w64-i686-gcc mingw-w64-x86_64-gcc mingw-w64-i686-glew mingw-w64-x86_64-glew mingw-w64-i686-SDL2 mingw-w64-i686-SDL mingw-w64-x86_64-SDL2 mingw-w64-x86_64-SDL python3

Clone the source code and enter its folder:

git clone https://github.com/Llennpie/Pluto && cd Pluto

Next, run explorer . to open a new File Explorer window at Pluto’s root directory. Drop your ROM in here and rename it to baserom.us.z64.

Begin compiling:

make

(You can optionally run make -j for a faster compile but at the cost of CPU usage.)

When completed, an executable will be created in Pluto\build\us_pc\.
