 That is the special feature that QEMU provides... Full emulation.
Nothing else gives you the ability to run a processor environment that
is completely alien to the actual hardware.

Of course, there is a performance penalty but YMMV... You are
comparing ancient hardware vs full emulation on modern hardware.
