What's with the recommendation for a YouTube MP3 converter near the bottom? There seems to be no technological relation so I can only guess the author got paid to include it, but you're legally supposed to disclose if something is a paid ad
according to wayback machine the domain expired at the end of 2021. Months later it came back with the sneaky ad. Their page at github https://includeos.github.io/ does not have it. It is safe to assume whoever grabbed the domain has no association to the authors. Project has been dead for many years now btw.
I might add RISC-V support myself, as I am the author of libriscv. We'll see.
