I have build a retropie driven GBA before, and it worked pretty good, but I was not very proud of it. So I started all over. This time I had a better understanding of components that work in small spaces and a 3D printer.
Fitting a 3.2 insch creen with controller in such a small case means that the screen, the PCB attached to it and the GBA itself needed some modifications. Everything is soldered together to save space and to create a more stable solution.
After fitting the amplifier, speakers, volume control, headphone connection, power board and battery and some software tweaking the GBA was done. Let's play!
