Compiling on Windows
Currently, the easiest way to install Saturn is with sm64pcBuilder2. It will automatically download, update, and manage Saturn with minimal setup.
You can find a YouTube guide for this below:
In case you still want to compile the repo manually, follow the steps below.
Compiling on Windows requires MSYS2. Download it and launch the MINGW64 executable (MINGW32/32-bit is untested).
Do not launch standard MSYS2. Search "MINGW" in the start menu and choose 64-bit. It has a blue icon.
Enter pacman -Syuu in the prompt and hit Enter. Press Y when it asks if you want to update packages. This updates the packages to their latest versions.
Copy/paste this command into the terminal to install 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 mingw-w64-x86_64-curl mingw-w64-x86_64-jsoncpp
Enter these two commands separately:
git clone https://github.com/Llennpie/Saturn
cd Saturn
Copy an unmodified, vanilla ROM into the repo's directory and rename it to baserom.us.z64.
Note that MSYS2's folders are different than Windows. You can run explorer . to open Saturn's directory on your computer.
make
You can optionally append -j4 where 4 is the number of cores your computer has. This may speed up the compiling process.
When finished, an executable will be created in /build/us_pc/.
If you've already built Saturn before, but want to update to a newer version, you can do so without repeating the above steps.
First, re-enter your Saturn directory:
cd Saturn
Pull the latest commit, and then run make once more.
git pull
make
