I am well aware of it having been pointed to it by a friend of mine. There's
also http://en.wikipedia.org/wiki/JPC_%28emulator%29 which is written in Java.
I tried jslinux and as cool as it is, it seemed very slow, even on my Core i3
machine. Emscripten seems to generate faster code, and since I hope the bug
getting "-O2" (or even "-O3" which is not always guaranteed to work
properly, but might work in my case) to work properly will be fixed, it may be
even faster than it currently is without any optimisations.

I wonder how usable will QEmu be after being compiled to JavaScript using
emscripten ... <evil-grin />.

Impressive.
