Data Table

Default entry size is 60 bytes (0x3C), but the first entry is smaller, the last entry is a bit special because is not linked to a file, and it looks like there is a padding at the end of the table

Filename Table

Each entry is composed by:

Offset	Length	Example	Name	Notes
0x0	0x4	00000038	Data Table entry offset	Same value than in the Data Table
0x4	variable	lib/rhm/Clear.fpo	File name
variable	0x1	00	NULL byte

• The end of the table has a padding to align to 0x10 bytes

File Table

The table starts with 0x20 bytes, are always present in all the .qrc files

Offset(h) 00 01 02 03  04 05 06 07  08 09 0A 0B  0C 0D 0E 0F
00000440  71 72 63 00  66 69 6C 65  2D 74 61 62  6C 65 00 66  qrc.file-table.f

• Marked in red: padding to align to 0x10 bytes

After this, the files are concatenated in the same order than in the Filename Table

Tools

ZLIB archivers

QRC files are compressed in ZLIB, and has 8 bytes added at the start of the file. To be able to use a generic zlib archiver is needed to remove this 8 bytes (and is needed to add them in the last step when rebuilding the QRC file)

SimplyZip

Windows archiver able to extract and create zlib files. http://www.paehl.de/cms/simplyzip

• Usage:
  • Open the program and click in the tab at top: [External progs] ---> [ZLIB (pack/unpack)]
  • A window opens where you can select the file
  • Choose [Decompress] or [Compress], then click in [Start]

QGL converter

This tool can decompress a QRCC to QRCF and compress a QRCF to QRCC (it crops/generates the first 8 bytes and manages the zlib decompression/compression)

https://raw.github.com/wargio/ps3tools/master/QGL.c (just run make to compile it)

QRC Extractors

After the ZLIB decompression (needed for all .qrc files except icontex.qrc) the contents can be extracted individually using different tools

• Notes
  • Some of the images are inverted vertically (only .dds?)

P3Textractor

Is posible to use a theme extractor to extract the contents from .qrc files, but first is needed to replace the characters / by _ of the text strings inside the Name table with a hexeditor (e.g: the string override/black/ICONS.mnu needs to be replaced by override_black_ICONS.mnu) This patching of the text strings can be automated by selecting the whole Name table in hexeditor and the function "replace string" (replacing the text string / by _ automatically only in the selected area)

P3Textractor manual: http://www.psdevwiki.com/ps3/Themes_(.p3t)#P3Textractor

• Notes
  • P3Textractor renames .dds file extensions to .gim in the extraction process... so is needed to change back the file extensions manually to .dds for further edits in other programs
  • This same trick with P3Textractor can be used with .raf files

Raw extractors

Generic Tiny little extractor

Theses generic tiny little tools extract blindly & embedded files and are means to be tiny and independent. Heavily based on an MPO splitter by Christian Steinruecken. Formats supported DDS/MNU/JPG/MPO/PNG (and virtually any other by modifying the source code)

http://rghost.net/49340892 (include Code-Compile-Credit. Drag and drop your file into them) & mirror links: http://mir.cr/0R78ED3U

QRC Compilers

There are no compilers for .qrc files, the commonly used method consist in patching settings values in text strings (or to inject the modded files) with a hexeditor over the original .qrc file

This limits the mods to patches than never exceeeds the size of the original data... in the case of patching an area with an smaller patch is recommended to fill the original "trash" data with zeroes

Patching strings in hexeditor

Mostly used with the settings inside .mnu files

First extract the files with some of the extractor tool, open the .mnu files 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 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
