Next step is to burn our custom image onto the SD card. This image is a custom version of RetroPie / Emulation Station with some free or open source games pre-loaded, and set up to work with the Joy Bonnet.

Click the button below to start downloading the image. This is a large file and may take awhile!

While that image downloads, go ahead and download Etcher. A free piece of software that will easily allow you to flash the image onto your SD card. Head to and download/install the correct version for your operating system.

Once the custom image file has downloaded, you will need to extract it. The file is a .rar file, so if you don't have any way to extract that file type, see below.

For Windows computers, use 7-Zip to extract the .rar file.

For Mac computers, use The Unarchiver.


Once you have extracted the .rar file, you should see a file called pizerogamer.img. Go ahead and open up the Etcher app. Click the Select image button and find the pizerogamer.img file. Then pull the micro SD card out of the 8GB SD card and insert the micro SD into the micro SD card reader provided. Plug this into your computer and Etcher should automatically find the drive. If not, click the Select drive button and find the SD card. Then click the Flash! button.

This can take some time to flash. While you wait, you can install the case onto your Pi Zero. Snap the Pi Zero into the bottom of the case, then put the top on. Once you have that done you can install your Joy Bonnet over the case like this:

Once you get the Flash Complete! screen in Etcher, go ahead and remove the micro SD card from the reader and install in your Pi Zero (there is an opening in the case to slide it in).

Support Your Joy Bonnet

Thanks to a hot tip from Adafruit Forums member cvadillo, you can take the extra piece of plastic from the case that you removed over the header pins, and use that to support your Joy Bonnet. Just slide it under the Joy Bonnet like so:

And now you are ready to hammer away on those buttons without worrying about causing stress on your hammer header connection.
