Sega Pico Pen Repair

When I bought a second-hand Sega Pico in 2015, I immediatly noticed that something must be wrong with it. I didn’t expect a lot of interactivity or gameplay, but at least it should let me draw something. It turned out that the pen was registering the position/movement and also made a clicking noise when pressed down, but nothing else happened. The error was quickly found and repaired (broken micro switch), but the photos have been waiting on my hard drive ever since.

This has arrived today from Ukraine: The new SD2SNES Mk.III aka SD2SNES Pro, designed by ikari_01 and manufactured by Krikzz.
