Believe it or not, 15 years later computers got faster, fast enough to cycle accurate emulate a x86 box - if you are using a M6 cpu, which has the fast single core performance ever.
As far as I'm aware emulation tends to be CPU intensive and can't really take advantage multi core . Is a M6 cpu core roughly 200x the performance of a 15 year intel core ? Something is wrong with my assumptions.
