Review on High-Performance Android TV Box 10.0: 4GB RAM, 64GB Storage, H616 Processor, Backlit Wireless Mini Keyboard, USB 3.0, 4K 8K Ultra HD, HDR, Dual Band WiFi 2.4GHz 5.8GHz, BT 4.0 - Set Top Box by Jeffrey Shatzel

I flashed Emuelec 4.0 to a 128GB micro SD card to play retro console games. Part, but don't expect every game to run flawlessly. I had no trouble pairing 2 Bluetooth controllers, but results may vary depending on the make/model of the controllers. One tip if you are trying to boot from a micro SD card for the first time, the reset button is hidden in 3.5. mm audio jack that needs to be pressed with a toothpick or similar while turning the device on. This should set the device to boot from the micro SD card first.
