Disassembler

Disassembler Syntax

This picker allows to choose how disassembler outputs commands. You can select between opcodes, command names and classes.

Labels and Variables

Disassembler will transform label and variable names to selected format.

Label Name Format

Global Offset

A label name is numeric e.g. @12345. The number is the offset of the label from the beginning of the source file.

Script+Local Offset

A label name includes a name of the script where the label is located (as defined with the script_name command) and the offset from the beginning of the script, e.g. @MAIN_12.

Script+Global Offset

A label name includes a name of the script where the label is located (as defined with the script_name command) and the offset from the beginning of the source file, e.g. @MAIN_12345.

File Name Format

This field specifies the path and name for disassembled text files using placeholder variables:

• $dir – input file directory path

• $name – input file name (without extension)

• $ext – input file extension

Example: Input file: C:\MyDir\main.scm

• $dir = C:\MyDir

• $name = main

• $ext = .scm

Using format $dir\$name.txt creates output file: C:\MyDir\main.txt

Options

Replace mission numbers

When this option is checked, the disassembler replaces mission numbers in start_mission with their names. The mission name is the label name defined in the file header. This name also could be used to quickly navigate to the mission code.

Insert original mission names

When this option is checked, the disassembler adds the mission title as a comment for the opcode start_mission and for the line DEFINE MISSION in the file header.

Disassemble with IF AND / IF OR

Disassembler replaces the number of conditions in the IF opcode with AND or OR

Always overwrite output file

This option determines how the disassembler treats the output file when a file with the same name exists already. By default the disassembler keeps the existing file and creates a new one with the extra number in the name (e.g. main[0].txt).

When this option is checked the disassembler replaces the existing file with a new file.

Manual IMG opening

When the disassembling process starts, the program searches the file script.img containing some game scripts. If this file is not present in the same folder with the .SCM file or in the San Andreas\data\scripts folder, the error message is displayed. If this option is enabled, a file select dialog appears and you can provide another script.img file manually.
