  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:

  5. #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!

  9. Armada, a 256 bytes #risc_os 3.5+ / RISC PC / RPI intro for NOVA 2026. #demoscene

    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 #arm assembler made with a custom ARMv2 #forth

    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/

  14. #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 👇
