This pulldown allows the user to chose the type of Atari machine emulated, and it's RAM size.Disable Basic
This checkbox determines if the Atari Basic cartridge is disabled when the emulator boots.Enable SIO Patch
The SIO (Serial Input/Output) patch is meant for speeding up disk operations. Originally, data between Atari computer and a disk drive is sent using slow, serial transmission (19200 bits per second). The Atari800 core emulator fully emulates the disk drive, so unlike other emulators it does not require the patch. However, it is much faster, if the emulator can immediately transfer data between a disk image and the Atari’s memory, skipping serial transmission emulation. The patch is only a change in the Atari OS, it does not disable real drive emulation.Enable H: Patch
This checkbox determines if the Hard Disk Drive Device patch is applied to the OS. The H: ('Hard Disk') device gives access to every file on your Macintosh to every Atari program. The device number specifies the base directory to be used and if the text conversion is applied:Enable P: Patch
Currently only ‘read file’ and ‘write file’ operations are supported by the H: device (delete file, rename file etc. won’t work).
- H0: – program directory, no conversion
- H1: - H4: – directories #1-#4, no conversion
- H5: – program directory, text conversion applied
- H6: - H9: – directories #1-#4, text conversion applied
This checkbox determines if the Printer Patch (P:) is applied to the emulator. When the patch is enabled, the user may then specifiy the command used to print. Within the command, %s is used to represent the file name of the temporary file generated during printing. For example, if you wanted the printed text to be opened in BBEdit, you would enter "bbedit %s" (without quotes) in the box. By default, the OSX command "open %s" is used, which will open the printed text in TextEdit by default, unless you have changed your file associations. The temporary files used for printing are created in your boot disks /tmp directory. Also, if you have UNIX priting set up, you could directly print using "lpr %s"Enable R: Patch
This checkbox determines if the Serial Port Patch (R:) is applied to the emulator. When the patch is enabled, the user may then specifiy the TCP port number to use to "dial-in" to BBS software using telnet in place of the original modem connection. Currently only dial-in capability is present. "Dial-Out" will be added in a future release.Boot From Cassette
This checkbox determines if the emulated Atari will boot from the emulated cassette when it is rebooted. After the boot, you must press the space key to start the cassette (like pressing Play on the actual recorder).Limit To Normal Atari Speed
This checkbox determines if the speed (in frames per second) of the emulator is limited to 50 or 60 (PAL or NTSC), of if it can free run, allowing it to run as fast as your Macintosh able. This feature can also be controlled from the Control Menu.Enable Sound
This checkbox determines if the playback of Atari Sound is emualted. This feature can also be controlled from the Sound Menu.Use Hi-Fi Sound
This checkbox determines if the new Hi-Fi version of Sound Emulation is used. The Hi-Fi sound will require more processing power, so you may not want to use it on slower machines. Changing this option requires the emulator to perform a coldboot, so you will loose what you are currently running on the Atari.Ignore Header Write Protect Bit On ATR Disk Images
This checkbox should be checked to ignore the Header Write Protect Bit that is set in some ATR disk images. It is unchecked by default, and should only be checked if the user needs to be able to write to an ATR image that has the bit set. When this box is checked, the user will be able to set the drive to either read-only or read/write in the Drive Management panel.
