I built a modern web UI around the v86 x86 emulator so you can boot classic OSes instantly—client-side, no installs. Includes Windows 1.01→XP, ReactOS, Haiku, Android x86, DSL, HBCD, plus custom .img/.iso upload. Would love feedback on performance + UX.

QEMU in general translates so called "extended basic blocks", then later "chains" them by overwriting the jump instruction [simplification].
This doesn't work well with WebAssembly, because each EBB needs its own module and chaining would be hard to implement since we can't patch existing modules. This is why currently qemu-wasm is so slow.
v86 has a different model of "jitting" the code, but it only supports x86 and each new architecture would require significant rewrites.

What exactly does yours do that http://copy.sh/v86 doesn't?
And great work ;)
Currently the closest thing is qemu-wasm, but my experiments (chrome only) show that it's still too slow: https://zb3.me/qemu-wasm-test/jspi-noffi/
