Atari800MacX is ported from the SDL version of this emulator, and added a full native Cocoa interface, including Preferences, Menus, File Associations, Help and more. Unlike the first primitive release, it now does not require libSDL to be installed seperately, but includes it within the application package. It does however require ROM image files from the original Atari systems, which are not included here.
Special Thanks go to Jacek Poplawski for writing the general SDL port, and the entire libSDL team that has made this port possible, as well as to the whole Atari800 team for their invaluable support and suggestions.
