Menus
Display Menu




The Display menu on the Atari800MacX emulator allows you to control the format of the display, grab the mouse input for mouse emulation, and take screenshots of the Atari screen.  It has the following menu selections:

Display Scale Factor Submenu
This submenu allows you to chose the scale factor that is used to display the emulated Atari screen in the window.  You may chose the display to be either 1x, 2x, 3x, or 4x the size of the Atari screen. This may also be set on the Display Tab page of the Preferences Window.
Display Width Submenu
This submenu lets you set the width of the emulated Atari screen in the window. You may choose between narrow, default, and full widths of the Atari screen.  These correspond to 320x240, 336x240, and 384x240 respectively. This may also be set on the Display Tab page of the Preferences Window.
Scaling Mode Submenu
This Submenu lets chose the type of  scaling to be applied to the screen.  Normal mode displays the screen without any smoothing or scanlines.  Scanline mode inserts scanlines as they might have appeared on old classic monitors or TV displays.  Smoothing mode applies a smoothing algorithm to the scaline, resulting in rounding in the scaling.  Note, however, that the smoothing mode can consume large quantities of processing time, slowing the emulation down.  You may want to check if you are able to run at full frame rate in this mode by using the "Show Frames Per Second" menu item.  This may also be set on the Display Tab page of the Preferences Window.
Artifacting Mode Submenu
This submenu lets you set choose how the emulator simulates Artifacting, which occurred when the original Atari used a TV for displaying its video.  Some games depended on the colors these Artifacting effects produced. This may also be set on the Display Tab page of the Preferences Window.
XEP80 Control Submenu
This submenu lets you set choose if the XEP80 80 Column Display adapter is connected, and if it is, to which joytick port, 1 or 2.
Toggle XEP80 mode (cmd-shift-X)
This menu item allows you to toggle between the normal Atari display and the XEP80 80 column display.  It is only enabled when the XEP80 is connected.
Toggle Fullscreen mode (cmd-F)
This menu item allows you to toggle the display between Fullscreen and Windowed modes.  More info on screen modes can be found on the Display Tab page of the Preferences Window.
Toggle FPS Display on/off (cmd-K)
This menu item allows you toggle on or off the display of the emulators frames per second in the Window Title. 
Grab Mouse mode on/off (F16)
This menu item toggles the emulators to control of the mouse for using it as an emulated Atari controller.  More information on Mouse emulation can be found on the Controllers Tab of the Preferences Window.
Screenshot (F13)
This menu items allows  you to take a screenshot of the Atari screen.  It will be stored as a .PCX format file in the same directory as the emulator executable.  Future versions of the emulator may use a more Macintosh graphics format, but for now this is the format the graphics core uses. The great Shareware program Graphic Converter may be used to read this format.
