Hi All,
After more than 3 months of work (that includes a lot of waiting for chinese deliveries), I'm proud to present my Gameboy HD project!
As you can see from the pics, it runs with a pi0.
The screen is a 640x480 3.5" tft running on 5v with analog video in.
The sound is managed with a USB sound card.
If you have any question on components or wiring, don't hesitate to ask!
