Tested editor Norman Chan teamed up with the engineer Brandon Farmer of TinyCircuits, an Akron, Ohio open source hardware company, while at Maker Faire 2017 to find out how they made their tiny arcade cabinet kits that actually play games while fitting in the palm of your hand. Brandon told that he and the team made the arcades to life by placing a powerful arduino board, memory, and a display screen into a micro laser-cut cabinet. You can buy these cabinets from the TinyCircuits website.
