Great project by aaroNiGHTS at IGN.
For a while now I’ve been wanting to do a project with the Raspberry Pi. The ultra low cost, single board computer is making roads in both education and the do-it-yourself maker scene. It’s a great platform to learn programming and basic electronics, and the heart of many enthusiast projects. After thinking about what I could make, I settled on an emulation-based arcade machine.
The new Raspberry Pi 2 pushes platform over the hump to be the ideal brains inside a homemade arcade system. Not only does it give you reasonably fast loading times and smooth menu navigation, but its quad-core Broadcom processor allows for emulation of power demanding games and platforms. The Pi platform also has a big advantage for an arcade machine – the General Purpose Input/Output pins allows standard arcade stick and buttons to be directly wired up to the unit, without any need for a keyboard simulator or any kind of USB controller. Using the Retrogame software, it’s just a matter of connecting each button or joystick direction to both an unused I/O and a ground pin.
A big factor in any arcade unit is the choice of monitor or screen. Natively the Raspberry Pi can output a HDMI signal at resolutions up to full 1080p, or an older Composite video signal like every console in the 90’s used. If you have a CRT or other older monitor you can get a cheap, sub $20, adapter to let you use a VGA connection.

Featured Adafruit Product!
HDMI to VGA Video Adapter: If you have a computer or tablet or device with HDMI output but you want to connect it to a projector, monitor or display with VGA input, you have come to the right place! This nifty adapter cable has a classic HDMI plug connector at one end and at the other end a DB-15 VGA connector (it has hex nuts that you can remove if you are trying to mate it with a cable that also has hex nuts). There’s also an audio jack on the side, this provides stereo headphone/line out (HDMI 1.3 cables carry both video and audio). You may also need a VGA DB15 male/male cable (not included but available in the shop) to connect this to your monitor. Read more.
