Small update. I finished my work on the controllers to be used in the backgrounds. Here is a sample of what they will look like and the colors.

I was not feeling the clean vector look so I went with something more crude. These will be used in the background on the main selection screen.

If there are any requests for other emulators to be themed it would probably be the time.
