Figure 20 - Emulators ..........................16 INTRODUCTION Feeling retro? Well so do we! This ABRA Arcade Kit will blast you back to the past all within the comforts of your own gaming station. The added bonus is no tokens required to play! This guide will show you how to connect the buttons and joystick and turn this simple cardboard box into a realistic game station emulator.

2 – ASSEMBLY 2.1 – ARCADE BOX The first step in assembling our Arcade kit is to prepare the box. Conveniently, the box this product came in was designed to be easily converted into the arcade. Carefully cut out the slots for buttons and joystick.
In dire situations, a dab of solder, hot glue or shrink wrap can ensure the wires are properly fastened. Check the wire was done properly by testing its continuity/conductivity with a multi-meter (use the meter in diode mode and place the leads on either end of the cable. If the screen shows a value or beeps, your connection is good.) Figure 3 - Button Ground Wire You will need 1 of these.
Repeat the same step as above with 4 connections. This cable of for grounding the joystick switches. Color-coding is a good idea here. Make sure to check the continuity at each connection node and the whole length of the cable. Figure 5 - Button Ground Connection Connect the common grounds of all buttons (bottom pin) with the cable we made.
Figure 7 - Joystick Signal Connection Figure 8 - Joystick Ground Connection Play with the joystick and identify each direction of motion with respect to how it will be mounted in the box. (Don’t worry if you get this backwards, you can re-assign the directions in the software later).
With all the wires connected, we can insert the hardware into the box. Screw in the buttons and screw down the joystick. 2.3 – RASPBERRY PI CONNECTIONS At this stage, we wire the Raspberry-Pi and seal up the box. Place the Raspberry-Pi inside the box at a convenient location that allows all the wires to reach it as well as has easy access for power, ethernet and HDMI cables.
2.3.4 – GPIO The Raspberry-Pi is easier to program with nothing connected. After you’ve uploaded the operating system (skip ahead to Section 3-SOFTWARE section), we can connect the GPIO (General Purpose Input Output) pins as should below.

3.3 – SD FORMATTING It is always good practice to format a MicroSD card (old or new) before flashing a new operating system (OS) onto it. Formatting wipes the previous contents off the disk and prepares the hardware for now data entries. To prevent SD card corruption, always “Safely Remove Hardware” when the SD card is connected in the computer.
Figure 18 - Controller Configuration For each command, press the corresponding button or joystick direction you wish to assign. If you wish to skip a command, simply hold down a button for 2 seconds. You may not assign the same button to 2 commands. 4.3 –...
4.5 – SOFTWARE UPDATE The Raspberry Pi community is constantly expanding and contributing its developments. This means that there are frequent updates to this software package which can be downloaded. It is a good idea to check them out every month or so. This process does require an internet connection. Navigate to the Configuration page for RetroPie.
Figure 20 - Emulators 4.7 – ADDING ROMS Now that we have an assembled arcade box, working buttons, screen display, audio and running emulators, the last step is to add ROMs to our system. The ROMs are the game data themselves and must be obtained from a reliable and legal source which expands beyond the scope of this tutorial.
