In recent years the term “open-source handheld” has basically drifted away from what it originally meant. Originally “open-source handheld” referred specifically to retro handhelds running open-source systems. Some were commercial products flashed with third-party firmware, like the early Subor RG97; others were open by design from the start, like the later Odroid Game series. But what comes to mind now when someone says “open-source handheld”? Generic molds, RK3566 SoCs, and a pile of messy emulators. Lately Android comes standard. Never mind whether the shell infringes on anyone’s design—the SoC’s own attitude toward the open-source community is questionable. That’s why overseas these products were never called “Opensource Handheld” but “Retro Handheld.” A handheld for playing retro games, so retro handheld. Makes sense. Today I’m talking about two retro handhelds you could call “closed-source handhelds”: the RG35XX from Anbernic (Zhou-ge), and the Miyoo Mini Plus from Miyoo, Zhou-ge’s nemesis.
