Data Decoding for Memory Items
Memory items have a typical count of 0x0C (for memories about an object) or 0x0D (for memories about a sim, including the owner) DataWords. The following list shows the structure of the Data:
0x0: Quality (0 = Positive (Green), 4 = Negative (Red)) 0x1: Year (seems to start in 1997, or 0 for no date) 0x2: Month (1 to 12, or 0 for no date) 0x3: Day (1 to 31, or 0 for no date) 0x4: Owner Instance 0x5: Subject GUID (low-order 16 bits) 0x6: Subject GUID (high-order 16 bits) 0x7: Initial Value (typical values seen: -100, -75, -50, 0, 50, 75, 100) 0x8: Minimum Value (typical values seen: 0, 5, A) 0x9: Daily Decay (some of the values seen: 25, 42, 96) 0xA: Current Value (absolute value should be between Minimum Value and Initial Value) 0xB: Unknown 0xC: Subject Instance (Optional. Subject Instance should be present when the Subject GUID refers to a sim.)
Owner Instance and Subject Instance are the Sim Description SDSC instance number for this sim.
Gossip is a memory where the Owner (in the Memory Data) is not the Sim who owns the NgbhSlot. In this case, the Sim who owns the NgbhSlot has a memory about the Owner.
The Current Value of a memory is a relative score of how the memory affects a sim's mood. Positive values improve mood, negative values make it worse. The Current Value of a memory starts at the Initial Value and decays towards zero over time. The Minimum Value is the closest to zero a memory can decay. Minimum Value and Daily Decay are normally unsigned values; their sign appears to be taken from the Initial Value.
