It is not a good example, the snes has 2 different cpus, gpu engine,
sound dsp engine ..., besides it is necessary a very accurate emulation
in order to sync the cpus. It does that it is changing from one cpu
to other very continually, around to every 2 or 3 opcodes. A simple 65816
emulation will be very fast in a old 486. Besides the snes emulators
uses interpreter cpu emulation, and it is very inefficient, the
last-generation emulators uses dynarec emulation, what is X times
faster. (good examples are ultrahle, corn or vgs).
Regards,
Carlos.
