My understanding of a patent (in the US) is that it’s only for new, novel concepts, often difficult to design or conceive.

Prior art, in this context, are just examples of this concept already in use or demonstrated. If there are already examples of the idea in use by others, then your idea isn’t new (and therefore not patentable).

Yes, but it only works with the original client. Doesn’t appear to work with OpenMW, yet, which is superior in many ways now.

The interface on the Miyoo Mini (with OnionOS) is a lot smoother and more streamlined than anything with Android. I definitely like how easily you can switch between all your recently played games so quickly, regardless of system.

Android devices tend to be a bit more flexible/powerful with more emulator options, but the interface isn’t as complete and more tweaking is needed. It’s not perfect, but I’m enjoying Diajisho.

It seems pretty common to use a different Google account on your device than your main one. I only use it to access the Play store, then I disable all Google services until I need it again.

But there’s really no right or wrong approach here, as long as you’re playing games and enjoying it.

Retroid makes some good stuff too.

I have a bunch of devices. Steam Deck, Miyoo Mini, Retroid Pocket 3+, Analogue Pocket, modded 3DS, and various modded Gameboys.

For most retro games, I find myself reaching for the RP3+ the most. Don’t get me wrong, all the other devices are great too, but it’s a great size and works without fuss up through PSP.

And for value/$, it’s hard to go wrong with any of the trending emulation devices, be it from Anbernic, Miyoo, or Retroid.
