I have a Pi 4B with 8 GB RAM and run Jellyfin plus some other stuff on it. Works great.

Had it first installed via repo but transcoding did not work at all. After switching to the Docker setup though, transcoding worked ok out of the box. Definitely takes a few seconds before the stream starts when having to transcode but no hiccups afterwards. Unless you jump around of course, and also I never had more than one stream trandcoding.

Now, yes. Unless this happens again.

I think I read recently about some emulator portal you can selfhost, would that be silly enough? Requires you to acquire ROMs though.

Well done you then, in this case!

I am not sure how Emudeck downloads Cemu though. I only found instructions on downgrading Cemu for Emudeck that you should download directly from Github and delete the Cemu file in the Emudeck folders.

Which might mean that Emudeck is setup to download directly from Github, not using Flathub. That would then result in a user receiving the malware if they had updated via Emudeck during this time.
