I wanted to make a case that has got the display and power ports on the back and the controller ports on the front. Like in the original.

I needed to make a small USB extension cord to get the controller port to the front of the case.

Lastly i used hot glue to keep everything in place.

This is a good time to test the USB port and the RetroPie image workings.

Put the SD card on the Raspberry pie and power it up.

On the first run you will need to configure the raspberry. Pug a USB keyboard to the Raspberry and follow the instructions given in the RetroPie site.

I will not tell you how to add games to the mini Nes. You should own the original game before downloading it in to the emulator. I'm not responsible of your actions.

The RetroPie image is how ever free to use.
