Atari800MacX Help Preferences Window Display Tab |
These radio buttons allow you to choose to display the emulator in a standard Aqua window, or to use the entire screen for displaying the emulator. When in full screen mode, normally you will want to check the Fullscreen Always 640x480 item. This will lock the display to a fixed size. If this item is unchecked, then the Scale Factor and Display Width parameters below still apply. The emulator will attempt to find a suitable mode. Note, not all modes will work with all display adapters. If the emulator suddenly quits when changing to full screen, the Scale Factor and Scale Mode were not compatible with your graphics card and fullscreen. You can also change the Display Mode setting from the Display Menu.Renderer:
These radio buttons allow you to which renderer Atari800MacX uses to display the screen. OpenGL requires a video card that supports OpenGL, but will be much faster at scaling the screen to larger sizes than the Software mode. However, OpenGL is slower at the Smooth scaling than the Software renderer. OpenGL is also more efficient in OSX 10.4 and high, where Apple has implemented something called "coalesced updates". If you are having speed or graphics problems on your particular machine, you may want to try the other renderer from what you are currently using. The default value in Atari800MacX 3.0 and higher is OpenGL.Scale Factor:
These radio buttons allow you to choose between the standard Atari Screen Size where one Atari pixel is mapped to one Macintosh pixel, 2xAtari Screen size (one Atari pixel is mapped to four, 2x2,Macintosh pixels), 3x Atari Screen size (one Atari pixel is mapped to nine, 3x3,Macintosh pixels), or 4x Atari Screen size (one Atari pixel is mapped to sixteen, 4x4,Macintosh pixels). You can also change this setting from the Display Menu. Note, on slower Macs, you may want to change your video depth to Thousands of Colors to achieve full frame rate when using more than 1x mode. (Don't change this while running the emulator!!!).Display Width:
These radio buttons allow you to choose between narrow, default, and full widths of the Atari screen. These correspond to 320x240, 336x240, and 384x240 respectively when in 1x Scale Factor mode. You can also change this setting from the Display Menu.Use Fullscreen Monitor:
This check box allows you to select the Debug Monitor to run in Fullscreen. Without this item checked, if the Debug Monitor runs (by pressing F8), or the Emulated machine crashes, and the unrecoverable error dialog runs, the emulator will leave Fullscreen and display the monitor or crash dialog in a window. With this item checked, the monitor will appear in fullscreen. You can also select the foreground and background colors for the monitor text. Note, you can currently only use the Fullscreen if you also select the Fullscreen Always 640x480 Item.Show Frames Per Second In Window Title
This checkbox lets you choose to display the Frames Per Second (FPS) that the emulator is running at the moment. This can be used to check that your Macintosh is fast enough to run the Atari at full speed. It should indicate 50fps for PAL, and 60fps for NTSC. FPS Display is not available in Fullscreen mode. However, since Fullscreen mode always runs in 256 colors, speed is usually not an issue. You can also change this setting from the Display Menu.Brushed Metal Appearance
This checkbox lets you choose it the windows in the emulator use the Standard Aqua appearance, or if they use the Brushed Metal appearance, ala Safari or iTunes. The emulator must be restarted after a change in this setting for it to take full effect. Note, you must be using OSX 10.3 or higher to used the Brushed Metal Appearance.TV Mode
These radio buttons allow you to choose to the refresh rate of the emulator, either NTSC (60 frames per second) or PAL (50 frames per second).
This pull down allows you to choose how often to redraw the simulated Atari screen. You can choose to do it every Atari frame, or every 2nd, 3rd, or 4th one. On very slow Macs, this could be used to bring the frame rate up to full speed (50 or 60 frames per second). The checkbox then lets you determine if player/missile collisions are detected in the frames that are skipped. By default, they are.
This pull down allows you to 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.Use New Artifacting
This checkbox allows you to choose if the new Artifacting method released in Atari800MacX 3.3 should be used. It produces much clearer text, and correctly varies luminance and displays player missile graphics in artifacted mode.Color Palette
These options allow the user to customize the colors used by the Macintosh to Emulate the Atari's color palette. 8-bit Atari machines have 256 colors, and the emulator can either generate a palette, or use a pre-generated palette stored in a file. By default, it uses the real.act file stored in the Palettes folder in the application directory.
If the "Use Palette from File" checkbox is checked, then you can choose the palette file with the Choose.. button. If you wish, you may then also check the "Adjust File Palette" checkbox to adjust the Black Level, White Level, and Intensity parameters described below. These adjustments do not affect the file itself.
If the "Use Palette from File" checkbox is not checked, then the emulator will generate a palette using the values you enter for the following 4 parameters:
- Black level adjusts brightness of Atari colors 0, 16, 32, etc. (darkest ones),
- White level adjusts brightness of Atari colors 15, 31, 47, etc. (lightest ones),
- Intensity adjusts saturation of all colors,
- Color shift adjusts hues to be used for Atari colors 16-255 (0-15 are always gray). A hue is used for colors 16-31, next one for colors 32-47, etc.
Each parameter must be an integer within range 0-255.Disk Leds
