Before mounting the components inside the case it is a good idea to connect them with one another to see whether everything works correctly. Feel free to use my attached "wiring diagram" as a reference. You might also want to try out the GPIOs of the Raspberry Pi as a controller input. Make sure to follow the second attached diagram for that. For more information about the Recalbox OS visit their site: https://www.recalbox.com/



For the audio output you will also need to create a RC filter circuit. The schematic is attached.

If you have problems with the settings of the Recalbox OS you can also use my attached configuration files as a reference or simply replace yours with mine.
