Richard Bannister is the man! He created and/or ported a but load of emulators to the MAC and everyone I tried so far works flawlessly! Check them out. http://www.bannister.org/software/index.htm There is an enhancer that works with just about all of them. It adds more features. Just thought i would share. I have been looking for a long time for good emulators for mac and I finally found them and they all work great!
