I have been working on converting the LEGO Gameboy model into a functional Gameboy (well emulator). Based on a ESP32 S3 (N8R8) chip on a custom pcb.
Along the way i had to figure out how to convert PWM audio to Analog (so i could have the same kind of volume pot-meter as the DMG). I also made a rough python script for importing model from LEGO Studio (stud.io) into Rhino 3D.
There are still things that could be optimized, but i will take a small break from the microscope for now.
