This device has not been tested by me - being sold as-is. The Hyperkin SmartBoy allows you to play real Nintendo Game Boy and Game Boy Colour cartridges on your Android phone. This device can only be used with certain phones, including the Google Pixel and Samsung Galaxy Note; please search online for all compatible phones. I do not have a compatible Android phone, so I can't test it. Being sold as-is. Asking $5, cash only.
