The other advantage of classic emulation is entropy... I got a Nintendo and all the games still, but half of 'em don't work without fiddling and cleaning for, oh, a half hour or so. Ditto for my 2600, Commidore, and Genesis. Emulation allows me to throw all of that stuff into a safe place as my personal memorabilia, and gives me back a half hour of my life which would otherwise being spent toying around with the system, cleaning, etc. Not to mention I don't have to scout the flea market anymore for the rare cart or floppy, unless I REALLY want the original copy.
