Review by William Morrow on Dec 19th 2016:
I am not very tech savvy. So it took me a couple hours to set up the Hyperkin Smartboy. Own a Blackberry Priv with its Android apps was a no brainer for me to buy the Smartboy. After set up tested a few Gameboy and Gameboy Color games to make sure they would actually play. Very happy with the purchase so far. For anyone interested make sure you push in the front bottom button to get the usb to connect to phone. Also make sure to push in middle button on back to open up hyperkin to allow phone fit in Smartboy then lightly squeeze for snug fit. Games look crisp & sound amazing on phone and respond well with Smartboy.
