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. On top of that, the V2 features a Showcase Mode. Once enabled, the software automatically cycles through your Game Boy and Game Boy Color games, booting a new title every minute to showcase the classic intro demos in a seamless, continuous loop. Powered via a rear USB port to keep the sides cable-free, it is the perfect solution for a clean and active display.
