What went wrong with the .m3u8 file? I’ve had lots of success ripping from websites using yt-dlp. For sites it doesn’t have explicit support for, it can fail if it can’t find the stream URL.

In those cases, I open the Network tab of Firefox’s developer tools and try to find something that looks like a stream URL, and then copy it out of there and give it to yt-dlp. (Don’t forget to surround the URL in double quotes if the URL contains an &)

If you provide the URL you’re trying to download from, I can try to take a look.

I use a random email address provided by DuckDuckGo for services that aren’t super important (each service gets its own random address)

I’ve never emulated PS3, but FMHY (freemediaheckyeah) is always my go-to starting point for answering this kind of question. They usually have awesome recommendations:

I’m guessing it either stores/modifies a file on your computer to let it know that it’s been installed before, or it might use an online check using some kind of hardware identifier.

If it checks online, Wireshark may help. What operating system are you using?
