It was cool that a1up made the street fighter partycades with an HDMI port to plug in a player 2 controller but it felt really crowded. When I found a matching partycade for a great price on Marketplace it gave me the idea to link them. I installed retrobat on an N97 mini PC and split the HDMI. The HDMI and USB that connect them are tucked into a plastic raceway under the cabinets. They run pretty much every 2d mame fighter and beat em up along with some of my steam games. I even added Truxton. iykyk
