Emulation of RISC-V in software;

container2wasm has TinyEmu for RISC-V.

Qemu also supports 32bit and 64bit RISC-V: "RISC-V System emulator — QEMU documentation" https://www.qemu.org/docs/master/system/target-riscv.html

Emu86 emulates RISC-V in Python and also WASM now IIRC: https://news.ycombinator.com/item?id=41899475 .. https://github.com/gcallah/Emu86/blob/master/assembler/virtu... :

  class RISCVMachine(VirtualMachine):

Also:

(Box96/Box64 emulates x86 on ARM64 and RISC-V; e.g. Portal)
