I'm looking into getting an alpine double din headunit with video input. How can I use this to play games in the car. Reason is I end up sitting in my car a lot waiting for people. I want something I can instantly turn on/off and I have a usb nes controller. How can do this without a full onboard computer?
And are there any systems that have all the games built in? I would like to keep it the least cluttered as possible.
