How do you get the AZTEC level in James Bond GoldenEye?

to get aztec you have to beat every mission in secret agent, but if you still think you are somewhat good compare to what you used to be you may as well beat everything in 00 agent and get it as well. There was a great video on youtube of this guy that beat the whole game in 00 agent in 64 minutes! pretty cool I'd say ha ha.
