There are no .qrc compilers, the | There are no .qrc compilers, the commonly used method to modify them consist in patching the text strings of the .MNU settings or to inject the custom files with a hexeditor overriting the original .qrc file | ||

==== Patching strings in hexeditor ==== | |||
Mostly used with the settings inside .mnu files | |||
First extract the files with the CXML decompiler script, look at the main .xml to identify the file names, open the .mnu file you want to modify in notepad++ to be able to read the settings in a easy way | |||
Select the string you want to modify and "copy" his name | |||
Open the .qrc file in a hexeditor (after ZLIB decompression if needed) and use the search funtion to locate the string you copyed previously | |||
*Notes | |||
**Most of the settings inside .mnu files are repeated several times inside the .qrc file because are used in several .mnu files... be sure to patch the correct .mnu file by comparing the rest of the data at his side | |||
==== Injecting files in hexeditor ==== | |||
Similar than patching a text string, but with a bigger chunk of data | |||
