Sigma Chess will store most of the menu and dialog settings in its preferences file (Sigma Chess 5 Prefs) in the System Folder. The Preferences Dialog, which is opened via the Preferences... command in the File menu, provides access to some more seldomly used options. Some of these have already been mentioned above.
The settings 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.
Messages : Where you can e.g. chose if Sigma Chess should announce mate, be able to resign etc.
Sound Effects : Where you can enable move sounds etc.
Analysis Format : Where you can specify how the analysis text is to be formatted (when analyzing games and collections).
Memory : Where you control how much memory to reserve for general use (e.g. opening games and collections).
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.
