> 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.

Thank you to the author for writing a GitHub page in 2026 that is entirely devoid of emoji.

Oh this is Luke Wren’s work. He’s an ASIC design engineer at Raspberry Pi. Amazing project, I love it!

This guy also designed DVI/HDMI from RP2040:

He works at Raspberry Pi, and designed the Hazard3 RISC-V core that is at the heart of the RP2350--although he did Hazard3 in his spare time. It's actually a fork of the "Hazard5" core that he designed for the RISCBoy.

The design was taped out on the first wafer.space run (see https://github.com/wafer-space/ws-run1) but I have not heard if it actually worked or not.

The programmable scanline-buffer-based rendering pipeline described in the PDF is worth a read for fans of such things.

i love the "hardware from an alternate universe" projects.

I'm surprised to see that it's OK that he has opensource AHB/APB stuff in it--I'd avoided learning them too much about them assuming that they were ARM proprietary.

AMBA has been an open standard for a really long time, I think maybe since it was released?

Does RISCBoy run Godot Engine? How can I make RISCBoy run Godot Engine?
3 hours ago
This is a much smaller device then anyone has ever exported Godot to.
More practical would be to port https://github.com/gbdk-2020/gbdk-2020 so that https://github.com/chrismaltby/gb-studio could support it.

If you set up the RISCBoy toolchain and port it then yeah.

No. You can't.

I'm quite willing to bet it can be done in this era of enabling developers with slob, which still usually works.

How can you fit Godot into 512KB of RAM? And with no GPU?
