...where do I start?
I modified so much on this thing...
As you can see I added two more buttons on the front (actually three) and two on the back.
I also added a little Speaker and a amplifier.
The circut board from the original controller was a pain in the a#*,
and I could´t get it to fit perfectly....so I made my own with a lot of buttons.
The buttons are controlled with an old keybord circut board which is hooked to one usb port of the pi.
It was all made with parts I had lying around (except the screen...which was the only thing I bought for this project),
thats why I had to adjust nearly everything inside to fit my parts.
(Sorry Adafruit but your stuff is very expensive here in Germany)
A lot of ports were removed from the pi to make it fit better. I also used a low profile SD adapter and covered the original hole.
Printed in 4 parts, sanded and painted...(a lot of work)
This baby runs perfectly on RetroPie and is a lot of fun :)
