wstrt where

A list of addresses in hex format is expected as input. The segments in which the specified addresses are located is calculated for each region. The result is output as a human and machine readable table.

This command is well suited to converting addresses into file offsets and vice versa.


1.   Syntax

wstrt WHERE address...

2.   Options

Option Param Description
--order pujk The parameter is scanned for the first appearance of letters P (for PAL), U (USA), J (JAPAN) and K (KOREA) to define the order of the output. Case is ignored. Missing letters are added automatically. The default is 'PUJK'.
-0 --no-0x Suppress 0x prefix of hex numbers.
-H --no-header Suppress the table header and footer and output exactly 1 line for each specified address. This makes the output more machine-readable.
-B --brief Same as --no-header.
-l --long Print file offsets too.

3.   Description

The command expects a list of keywords and addresses in hexadecimal notation with or without 0x prefix.

Keywords are PAL, USA, JAPAN, KOREA, or any abbreviation of them. The case of the keywords is not relevant. They select the region for following file offsets. The region can be changed in the middle of the command line. If the region is not specified, PAL is used.

The hex numbers are interpreted as addresses independent of the active region, or as file offsets dependent of the active region. If the number begins with M or m, then it is interpreted as an offset for file main.dol. If the number begins with S or s, then it is interpreted as an offset for file staticr.rel. If a number with exactly 6 digits and without the 0x prefix is entered, the value 0x80000000 is added. This makes it easier to check cheat codes, where often only 6 digits are used for the address.

In addition, a single minus sign is accepted to display a separating line.

The result is output as a human and machine readable table. Option --no-header (short: -H) improves machine-readability. Option --no-0x (short: -0) suppresses the output of the 0x prefix. If option --long (short: -l) is set, the file offsets are printed too.
