That's easy - download the image from retropie.org.uk/download and install it. We don't support 3rd party images - like the one you seem to have installed.

So the only things I plan on adding are a trackball, some low profile casters for the back, and some levelers for the front. I didn't know exactly what casters I wanted before starting the build, or else I would have cut them in before I built it. It's not that big a deal to do it after the fact, but I'm worried about getting a bunch of saw dust between the plexi and the monitor which will be a royal pain to clean. Other than that, I just picked up an 8 bitdo bluetooth controller to supplement playing on some of the console systems. I haven't had time to play or sync it with the arcade yet. So far, that's about it. Maybe I'll come back with some updates once I've played with it for awhile. It seems there are always some things you would do differently once you own things for a while!

Here are some closeups of the outside and some of the inner workings.

Also, it appears as though Hyperpie Motion Blue is a 3rd party image, which are not supported here.
