http://desmume.org/The new things in this release are a Cocoa port and translations support for Gtk-glade port.
With the Cocoa port, Mac OS X users can now fully enjoy DeSmuME on their favorite system! The Mac port doesn’t yet have all the features of the other ports but should run all games with near same compatibility. (DeSmuME running on Mac OS X)
Translations are now available on three ports: Cocoa, Gtk-glade and Windows, feel free to send us new translations (there’s instructions on how to do it in README.TRANSLATION).
