It's seems to be very different. box86 is user-space. Faux86 is bare metal. (minimum overhead iiuc). box86 is fully x86 ISA compliant and OpenGL. Faux86 seems now as 8086/80186.

What about porting box86 to Symbian 9.x (S60v3/S60v5)? Is it possible?

  Not really, I would think. You'd lose most of the advantage. Box86's trick is to intercept x86 system and library calls, and invoke the native ARM equivalent. Symbian, as a different underlying operating system, has no native ARM equivalents of the various x86 Linux system calls and common libraries. So you'd have to emulate those somehow, perhaps by translating them into Symbian-appropriate calls. Speaking more generally, a JIT translator would otherwise be relatively easy to port as a straight C or C++ library.

      Ah! I see what you mean there. An emulator that could take an x86 Symbian binary and translate the calls like this for ARM Symbian. Yes, that should probably be technically possible.
