Bring back the fun and nostalgia from the days of old with the Hyperkin SmartBoy! With this device, you can turn your smartphone into a Gameboy Advance or Game Boy Color. All you need to do is to attach the SmartBoy to your device and start your favorite game. It features the classic-style tactile button set, up-scales the phone’s resolution, and does not require batteries (hell yeah!!111). It’s also compatible with other apps and games, including GBA apps from Google Play. A caveat here is that it only works with Android smartphones (with USB Type-C Version).
