I would vouch for Thunder for Android and it has iOS version too. But I don’t think it can override the system font, so it is out of your requirement.

I only know two desktop apps on Linux, both of them are available on Flathub.

• Interstellar
• Lemonade

It looks like only Interstellar is still maintained, Lemonade last update was a year ago.

Love photon. It is quite usabale as PWA too on Android, though I use Thunder instead.

Yes, it is pretty much the same. All configs from citra can be used for lime3ds.

Very good. Now what brand of toothpaste is he using?

This is pretty ironic and tragic

AFAIK firmware update is handled by fwupd. Not sure if those wrapper included that.

While I don’t recommend using unmaintained version of an OS, you can find Fedora torrent files here. Might as well explore other distro if Fedora doesn’t work for your laptop. (I am biased with Solus).
