As KING COLD already pointed out you don't HAVE TO use an emulator to get a Mac version good to go... it is enough if you have the Mac core which you can find here
You must be registered to see the links
and simply download a full version of Windows - extract it's www folder - place it's content into it's respective place on Mac - and you are good to go !
If you want to use emulator though ( dependent on your rig of course ) I'd go with VirtualBox - PlayOnMac - Wine mix... ( Wine won't do if you have ARM chipset keep in mind ! )
