Hi, this is a small portable ARCADE controller. It uses a SAMSUNG Galaxy Tab S4 as the computer, monitor, speakers. An ipac keyboard encoder is plugged into the usb-C port of the Tablet. It runs Mame4droid with v139 roms. It plays all the games full speed, i havent noticed any slowdowns or lag. I usually play 20 minutes to an hour and the Tablet battery barely goes down a few percent. It has Industrias Lorenzo push buttons, Sanwa JLF joysticks with cherry microswitches and oversized actuators. The 4-way joystick has an 0.5mm oversized actuator and the stock square gate set to 4-way position. The 8-way joystick has an 1mm oversized actuator and a circular gate. I made a youtube video that goes into great detail. The project started because i wanted to play the early 80s gambling type games from company GrayHound. Those games give off a goldern era vibe. Eventually it turned into this laptop playable controller that plays many types of games. I mostly play it sitting on the couch, its very comfortable to use. My main area of interest is arcade games from 1978-1984. Im an old dude, and during those years the cool thing to do was go to the arcade. Thanks
