Someone is trying to boot Linux from a Scratch project. 😮🤯😻 In fact, it's a RISC-V emulator programmed with Scratch. Here is his journey (quoting the author):

I actually started this project with not very much understanding of RISC-V, but after a few hours of debugging I got the hang of it. The emulator was actually based of off https://github.com/cnlohr/mini-rv32ima, which i ported to Java a while back, and from Java I ported to SCPP (A programming language I wrote) and from SCPP I ported it to here [(i.e. plain Scratch)].

Regarding SCPP:

SCPP (Scratch C Plus Plus) https://github.com/Its-Jakey/SCPP

It's really interesting to see the creativity of people that learned programming with Scratch, then start exploring new horizons to eventually come back to Scratch. https://www.reddit.com/r/scratch/comments/12k8kvu/got_linux_booting_on_scratch/
