RetroBoy 5"

Here is my new built RetroBoy
It runs with Recalbox

I designed the case myself.
It was inspired by https://www.thingiverse.com/thing:2248709
but i didn't like the built in gamepad, so i designed it myself with a self built one.
Also the 4.2V to 5V Step-Up didn't work properly, so I changed it to 8.4V to 5V Step-Down.
