Thank you for your review
Email me when discounted: 
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. more...

What's New

Version 4.6.0:

Note: This may be the last release supporting PPC, 10.4, and possibly 10.5. If you have any bugs you need fixed or new features you feel you have to have for these older versions, please email me and I will consider them.

Bugs Fixed:
  • Fixed issues with arrow keys in full screen menu and some of the Atari arrow key mappings.
  • Fixed issues with assigning tab, return, and delete more...


Mac OS X 10.4 or later

Nostalgia mode on !

Searching for roms isn't particularly difficult and you are in no time in the late 80s.
What can I say? It works and it brings you back in the good-old era of computer nerds.

Thumbs up.

I just downloaded it today, and I am enjoying it. I finally found that I need to use preferences to set the joystick replacement. Now if I can only get the function keys to work for Select & Start.

I love it.

Emuparadise is full of popups that are awful in Safari. Don't touch it.

Did you go to the file menu and click "Block Pop-up Windows"??

Not one pop-up for me.

This is a good cocoa native emulator. I haven't tested compatability much, but interface and speed are good.
