Mario Golf Super Rush "42" file?

[DogToon64]

I figured out how to extract the "42" file. I put the files in the same folder as the "42" file, like ninetalescommander said. But instead of opening Windows PowerShell, I simply clicked on the "extract_42" file and it extracted the contents inside the "42" file (like ninetalescommander also mentioned, it will take a while to extract).

However, the python script only supports the first version of the game, the latest version isn't compatible with said script. Hopefully there will be a way to extract the files for the latest version of Mario Golf: Super Rush.
