they extended one set of assembly instructions with a bit of another. instruction sets are determined by the hardware and are called the architecture. RISCV is an extensible architecture meaning you can add in additional instructions without breaking compatibility with programs targeting the architecture.

I know as much as that and that intel has like a giant black box and gatekeeps giving people instructions (and prevents people from being able to fix their fuck ups, backdoors etc)

the x86 instruction set is public. implementing it breaks copyright law, if you aren't AMD or Intel. it has to be public or compilers/interpreters/assembly code couldn't exist.

Thanks for clarifying that, it sounded insanely impractical
