One other thing to try: https://addons.mozilla.org/firefox/addon/video-downloadhelper (presumably also available for other browsers). Then hold shift while you reload the page, and play the media. Chances are extremely good the addon will catch it and start dancing in your toolbar. Open the addon, click the file you want to download, and it should just download.

Fitgirl’s repacks already contain the necessary files. These steps are unnecessary. There are also alternative ways of sourcing the files. :)

In what way does yuzu require a Switch? That hasn’t been my experience.
