I recently repurposed an old Raspberry Pi 3 (model B+) I had laying around the house into a retro gaming machine, using RetroPie. I’m not into gaming — I haven’t owned a console since the Game Boy Advance — but I enjoy the music and visuals of old games, I find them relaxing. More specifically, I’ve been having much fun playing EarthBound.
(I have another Raspberry Pi in the house set up with Pi-hole, blocking any incoming ad at source. I rarely have issues with it except when I bought a Samsung TV: the T&Cs weren’t even loading. Serves me well for buying from a company which delivers ads in their users’ home screen).
