[edit] Notes

The 1-byte Goto statements in 8001-8006 appear to use the same codes as was used in The Sims 1:

  • 0xFD as Error
  • 0xFE as True
  • 0xFF as False.

The 2-byte Goto statements in 8007-8009 use these Goto codes:

  • 0xFFFC as Error
  • 0xFFFD as True
  • 0xFFFE as False.

The 8007-8009 formats can contain more than 256 seperate instructions, thus the use of 2-byte Goto statements.

[edit] Notes

Number of each signature type (0x8000 - 0x8007) contained in (original) objects.package:

  • 0x8000 - 1
  • 0x8001 - 2
  • 0x8002 - 25
  • 0x8003 - 75
  • 0x8004 - 4
  • 0x8005 - 285
  • 0x8006 - 1,357
  • 0x8007 - 15,507
  • 0x8008 & 0x8009 introduced later
