Box64 and RISC-V in 2024: What It Takes to Run the Witcher 3 on RISC-V

> At least in the context of x86 emulation, among all 3 architectures we support, RISC-V is the least expressive one.

RISC was explained to me as a reduced instruction set computer in computer science history classes, but I see a lot of articles and proposed new RISC-V profiles about "we just need a few more instructions to get feature parity".

I understand that RISC-V is just a convenient alternative to other platforms for most people, but does this also mean the RISC dream is dead?

Is there a RISC dream? I think there is an efficiency "dream", there is a performance "dream", there is a cost "dream" — there are even low-complexity relative to cost, performance and efficiency "dreams" — but a RISC dream? Who cares more about RISC than cost, performance, efficiency and simplicity?

But we define the RISC dream as a dream that efficiency, performance and low-cost could be achieved by cores with very small instruction sets?

If adding more instructions negatively impacts efficiency, performance, cost and complexity, nobody would do it.
