This is a simple adapter to fit the Seengreat 2inch LCD display into Lego's Game Boy model (72046). You can drive the display with almost any microcontroller to show on your Lego Game Boy whatever you like. An example for running an actual emulator on a Raspberry Pi Pico (rp2350-zero) can be found at there.oughta.be/a/lego-game-boy.
The author marked this model as their own original creation.
