What makes BlockBoy unique
What sets the BlockBoy apart is the obsessive attention to detail. The 2.8 inch display is software-fitted to perfectly fill the window of the LEGO® Game Boy™ set, providing a full and crisp image. Volume and brightness are both managed via custom buttons at the original wheel positions, and the original LEGO power switch turns the BlockBoy on and off. To ensure an authentic feel, the D-pad and A/B buttons use membrane switches, just like the original Game Boy.
