README
README.mdPico Gameboy
I came across with this DIY Gameboy video made of Raspberry Pi Pico and inspired me to build my own version. The fact that RP2040 has dual-core ARM Cortex-M0+ processor makes it capable of running some light emulators. So I’ll build a little handheld game console using RP2040 that can run gameboy!

Questions
How big is the Gameboy PCB?
It measures 130 × 51 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Gameboy use?
60 parts, built around the RP2040, RT6150BGQW and W25Q64JVXGIQ. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Gameboy KiCad files?
From the Hung-Chi970104/gameboy repository on GitHub, at the commit this page was made from: the board is Game_boy.kicad_pcb and its schematic Game_boy.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Gameboy design in my own project?
Its repository states no licence, so its author keeps all rights: ask Hung-Chi970104 before reusing the design.
