SNOOKER.DAT contains timestamps for all active games, and maps these to a 11-DWORD block (44 byte) each. This is used for making TRN files.

The file is located in the WINPLAN directory.

 +0     WORD    Number of the current entry (1..40), telling which of the
                timestamps was added last.
 +2  40 RECORDs of 18 bytes each, containing the time stamps of unpacked
                turns.
+722 40 RECORDs of 44 bytes. These entries correspond with the timestamp
                entries and contain random values.

When unpacking a result file, Winplan checks if it already knows the time stamp and if not adds a record containing the timestamp plus 44 random bytes to this file.

When making TRN files, the Id block in the TRN will contain the corresponding 44-byte block. Winplan will neither load nor MAKETURN for games not "registered" here ("Game data is stale").

This is a testing version.
It may be incomplete, and have more bugs (or features) than the public live version at planetscentral.com.
