  1. Some people asked about performance, so here is a video of #RISC_OS #Merlin booting (instantly) and running a graphics demo in #QEMU, Merlin is using its own software framebuffer in this demo, not yet GPU acceleration:

  3. #RISC_OS: I finally had a bit of time to upload a video with the first system boot into graphic demo for #MerlinOS It works fine on @raspberrypi 2, 3 and 4, but the video is from #QEMU which makes it easy to record both #kernel logs and Pi 2 display. Enjoy!

  5. Armada, a 256 bytes 3.5+ / RISC PC / RPI intro for NOVA 2026.

    640x512, 32 bpp showing XOR patterns mixed with HAKMEM 149 algorithm and a "blur" pass.

    64 instructions total

    write-up : onirom.fr/wiki/codegolf/armada/

    This was assembled on RPCEmu with a custom assembler made with a custom ARMv2

    Many great prods at NOVA, especially liked ZX spectrum "Arc", DOS "Glaze" and SNES "Niether Portal" in tiny category, also the C64 glitchy one : demozoo.org/parties/5354/

  7. #RISC_OS folks May the 4th be with you! Announcing a new Forth Compiler coming to RISC OS for this autumn (will be unveiled at the London Show this October, together with many other things). The cool bits are in the thread below 👇

  9. #RISC_OS finally after a month of battling, I have decoded and sucesfully reverse engineered the way ShareFS handle the distribution of updates to all connected clients! #ShareFSServer is now capable of updating all clients. Stay tuned for next build soon!

  11. #RISC_OS folks, new test release for ShareFSServer available to all the alpha testers. Link with all the changelogs below. To download the new build the link is the same as always. Please let me know if you find any problems.

  13. #RISC_OS : Antoher tough piece of work for Merlin, an extended and fully multi-core VDU driver. It's working and cores can do VDU requests who are being rendered correctly on the screen.

    And yes it's ugly 😂 I should find the time and make a video of the tests...

  15. #RISC_OS : Simon's PR is always quite minimalistic, so let's make this to spread please. He is working on one of the few projects to reimplement RO in a more modern fashion and today he shared that his work has finally achieved WIMP running on multi-core!!! video:
