Entry Format
The signature defines the structure of the each instruction.
8000, 8001 & 8002
(instruction length: 12 bytes)
- WORD
- Function/OpCode

- Goto on true
- Byte
- Goto on false
- 8 bytes
- Operands
8003 & 8004
(instruction length: 20 bytes)
- WORD
- Function/OpCode
- Byte
- Goto on true
- Byte
- Goto on false
- 16 bytes
- Operands
8005 & 8006
(instruction length: 21 bytes)
- WORD
- Function/OpCode
- Byte
- Goto on True
- Byte
- Goto on False
- Byte
- Node version (Flag - 0x00 or 0x01)
- 16 bytes
- Operands
8007 & 8008
(instruction length: 23 bytes)
- WORD
- Function/OpCode
- WORD
- Goto on true
- WORD
- Goto on false
- Byte
- Node version (Flag - 0x00 or 0x01)
- 16 bytes
- Operands
8009
(instruction length: 24 bytes)
- WORD
- Function/OpCode
- WORD
- Goto on true
- WORD
- Goto on false
- Byte
- Node version (Flag - 0x00 or 0x01)
- 16 bytes
- Operands
- Byte
- Cache flags
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.
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
