What is Atari800MacX?
This is the the Macintosh OSX Port of David Firth's Fantastic Atari 800 Emulator. Ported is the SDL version of the Atrari800 emulator to Mac OSX, and added a full native Cocoa interface, including Preferences, Menus, File Associations, Help and more. It does not require libSDL to be installed separately, but includes it within the application package. It does however require ROM image files from the original Atari systems, which are not included.
