 You will need to decompress the NTSC-U N64 Majora's Mask ROM (sha1: d6133ace5afaa0882cf214cf88daba39e266c078) before running the recompiler.
 
 There are a few tools that can do it:

 Voilà! You should now have a `Zelda64Recompiled` executable in the build directory! If you used Visual Studio this will be `out/build/x64-[Configuration]` and if you used the provided CMake commands then this will be `build-cmake`. You will need to run the executable out of the root folder of this project or copy the assets folder to the build folder to run it.
