Bochs [ 10258 ]
In terms of emulation quality, bochs rates very highly. It emulates the CPU completely - so it can emulate a PC on a non-PC architecture (so you could run DOS or even windows on an Apple Mac, or a Cray-II).

It's SLOW though - because it does do the complete emulation of a CPU and associated circuitry.

Some other emulators (like VMware) don't do true emulation - they pass through a lot of instructions straight to the real CPU underneath. Which is fast, but means you can only ever run vmware on an intel box.

Because the xbox is an intel box at heart, faster passthru style emulation of an intel CPU is possible. I don't know anything about emulators on the xbox except bochs though :-)
