From the project
Portable games console, designed from scratch: CPU, graphics, PCB, and the kitchen sink
RISCBoy is an open-source portable games console, designed from scratch. This includes:
- A RISC-V compatible CPU - A raster graphics pipeline and display controller - Other chip infrastructure: busfabric, memory controllers, UART, GPIO etc. - A PCB layout in KiCad
It is a Gameboy Advance from a parallel universe where RISC-V existed in 2001. A love letter to the handheld consoles from my childhood, and a 3AM drunk text to the technology that powered them.
