    From the GitHub page:

      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!
    • LukeShu 12 hours ago
      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:

      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.

    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?

      Its not a computer, its a small device. You dont have many unknown peripheral you dont have other programs. The memory and peripherals are there, just use them. Heap is complicated ? Preallocate everything. A peripheral is not used ? Just leave it there. Security ? Of what ? Thats the appeal of those devices.

      Why do you want an engine? Just write games

      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.

    • bananaboy 13 hours ago
      If you set up the RISCBoy toolchain and port it then yeah.

      No. You can't.
      • emilfihlman 13 hours ago
        I'm quite willing to bet it can be done in this era of enabling developers with slob, which still usually works.
        • Narishma 12 hours ago
          How can you fit Godot into 512KB of RAM? And with no GPU?
