From the GitHub page:<p>> 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.

    I mean no disrespect to Luke Wren, but he did not write it in 2026; he wrote it in 2018-2021. :)

    on the other hand having emoji on the readme is a great signal of llm-slop on my radar

      Isn't that the same hand?

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

  I think "ASIC design" engineer is under-selling him--he's working on their CPU cores too!

    Haha yeah I just went by his LinkedIn title

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

This guy also designed DVI/HDMI from RP2040:<p><a href="https://github.com/Wren6991/PicoDVI" rel="nofollow">https://github.com/Wren6991/PicoDVI</a>

  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 <a href="https://github.com/wafer-space/ws-run1" rel="nofollow">https://github.com/wafer-space/ws-run1</a>) but I have not heard if it actually worked or not.

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?
- ZiiS4 hours ago
  This is a much smaller device then anyone has ever exported Godot to.<p>More practical would be to port <a href="https://github.com/gbdk-2020/gbdk-2020" rel="nofollow">https://github.com/gbdk-2020/gbdk-2020</a> so that <a href="https://github.com/chrismaltby/gb-studio" rel="nofollow">https://github.com/chrismaltby/gb-studio</a> could support it.

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

  No. You can't.
  - emilfihlman12 hours ago
    I'm quite willing to bet it can be done in this era of enabling developers with slob, which still usually works.
    - Narishma12 hours ago
      How can you fit Godot into 512KB of RAM? And with no GPU?
