I’m trying to figure out if I wanna get one of these for the family to share and they look pretty cheap. I like that the ones I see advertised come preloaded with games so I don’t have to do all the setup and downloading. But I’m capable of doing that setup if there’s a better device that doesn’t come preloaded.
Of ones I’ve tried, Miyoo Mini Plus is excellent if you have any affinity for the Game Boy [Color/Pocket]. There are two great OS options available (MiniUI and Onion) that support the most important function: Sleep Mode that doesn’t drain your battery. It’s not the best form factor for long play sessions, but if you’re looking for some shorter hits of nostalgia, it’s wonderful.
RG35XX is similar and highly regarded, and the new SP form factor seems ideal for tossing in a bag.
To echo others: definitely get your own SD card.
