13. Preferences

Sigma Chess will store most of the menu and dialog settings in its preferences file (Sigma Chess 6 Prefs) in the System Folder. The Preferences Dialog, which is opened via the Preferences... command in the File menu, provides access to some less frequently used options. Some of these have already been mentioned above.

The settings are divided into the following groups:

General
Where you should enter your name, and control if the 3D board should be enabled (disabling it will save some memory).

Games
Where you can control how games are opened, and if "game saves" should be confirmed, etc.

Collections & PGN
Defines various options for Collections and PGN importing and formatting.

Scores & Analysis
Defines the formatting of Sigma Chess's scoring and analysis.

Messages & Sounds
Where you can choose, for example, if Sigma Chess should announce mate, be able to resign, etc. Also you can enable move sounds.

Misc
Contains a few miscellaneous options.

Memory
Where you control how much memory to reserve for general use (e.g. opening games and collections). Only available/necessary under OS 9.

Transposition Tables
Where you control the maximum transposition table size per engine "instance".

The Default button resets the dialog settings with the default values. This operation does not affect the menu settings.
