I can do emulation with a regular keyboardless rpi connected to my tv. You want portable emulation? I do that with a gpi case, and runs on batteries! This weird desktop approach is what doesn’t make any sense to me.

I could stream a beefier PC to it with sunshine/moonlight maybe and use it as some kind of really light desktop, but still, why would I do that and not just have the beefier PC in said desk.
