For all those who feared their Game Boy days would be but a memory, worry no more! The Game Boy may be dead, but with the Pico-GB you’ll have a chance to revive it.
The Pico-GB is a retro-gaming emulation console that ressembles to the original Nintendo Game Boy released in 1989.
It is based on the $4 Raspberry Pi Pico microcontroller. The case and buttons are 3D printed. The screen is a 2.2-inch LCD with a resolution of 220×176 pixels and 65K colors. There are 8 buttons: 4 for the DPAD + 4 action buttons (A, B, select, start). The buttons are 6x6x6mm micro push buttons. The sound is provided by a simple piezo buzzer.
The Pico-GB can play original Game Boy DMG games using the RP2040-GB (DMG) Game Boy emulator from Mahyar Koshkouei (deltabeard).
