I've revisited quite a few of the emulators I discussed earlier in my Retrogaming and Beyond on Mac OS X - article on various intel macintoshes ranging from a +- 1.4Ghz Intel machine with Ati 3D accelerated graphics to a +- 2.8Ghz Intel machine with Ati 3D accelerated graphics. Just to see if those new Mac's are up to the challenge (two Powerbooks, a macmini core solo and mini core duo, an acertosh and asustosh)
