WinUAE already allows you to run the emulator with 8MB Chip RAM.
As for AAA, I doubt there is any software therefore not much of a reason to write an emulator for it. Then again, MESS can emulate a C65 which was never released but working units managed to get out into many peoples hands (mine included) after Commodore was sold off. That is what gave people the ability to work up emulation of it. I don't think there are that many AAA machines around for people to poke at to come up with emulators for it. I could be wrong though. I would love to have one of those machines in my collection, but you just never see them.
