Editing Talk:Resource Container (RCO)

All RCO files contains a version number, the version increases with bigger firmwares but not for every firmware and is not directly associated with it. The same versioning method is used in PSP and PS3 RCO's

It seems all the RCO's of a specific firmware shares the same version (verifyed for firmware 4.76) and seems to be the version of the "rco set", or the version of the "rco tool" used to compile the whole "rco set". RCOmage v1.1.1 (latest stable) identifyes the version with a list of hardcoded values

switch(rco->verId) {

case 0x70: fputs("1.0", fp); break;

Example... sysconf_plugin.rco from PS3 firmware 2.00 with version 0x106

<RcoFile UMDFlag="0" rcomageXmlVer="1.1" type="ps3" minFirmwareVer="unknownId0x106">

all OFW 1.00-4.75 hashes: https://www.mirrorcreator.com/files/7KCMQKWQ/RCO-hashreport.7z_links <--- please someone convert this in a "human readable wiki table"

*PSP 6.60 and 6.61 firmware contains 63 .rco files (same files for both firmwares). Two of them are specific for PSPgo model (bluetooth_plugin.rco, slide_plugin.rco)

*Only 10 of them are compresed with ZLIB (dd_helper.rco, dnas_plugin.rco, htmlviewer_plugin.rco, lftv_rmc_univer3in1.rco, lftv_rmc_univer3in1_jp.rco, lftv_rmc_univertuner.rco, lftv_rmc_univertuner_jp.rco, lftv_tuner_jp_jp.rco, lftv_tuner_us_en.rco, oneseg_plugin.rco). All the others are compressed with RLZ (and RLZ decompression is not supported by rcomage, is needed to use Resurssiklunssi v0.3 to rebuild them)

***The converted files will have '''minFirmwareVer="2.6"''' (the original value is lost in the conversion)

This is a temporal section for tests using rcomage to create frankensteins .rco files smallest as posible that could serve as an explain of his structure. Will contain the source xml file used to create the rco, a big table with ALL the values of the structure, and a sample in hexview of the created rco. Eventually one (or a couple) of this tables will be moved to front page but by now this is a shared notepad and experimentation to see how to make that tables intuitive, pretty, and smallest posible, feel free to add other examples

The .xml below is the RCOXML source file used to create the .rco. The file '''image_test.gim''' is a dummy of 8 bytes filed with 8888888888888888

<RcoFile UMDFlag="0" rcomageXmlVer="1.1" type="ps3" minFirmwareVer="unknownId0x130">

<MainTree name="test">

**<span style="background:#7777ff;">00 00 00 F4</span> the offset where the image data starts, because the area before the image data has been compressed his position has been displaced

**<span style="background:#ffff00;">00 00 00 44</span> <span style="background:#ffff00;">00 00 00 A4</span> <span style="background:#ffff00;">00 00 00 00</span> the info about the compressed area that comes next (composed by: lenPacked, lenUnpacked, and lenLongestText)

==ImageTree with 2 images==

This example is intended to replace the previous one (but by now i dont want to delete the previous one). It can help to see how the offsets are cummulated and the optional paddings to align to boundary

The .xml below is the RCOXML source file used to create the .rco. The file '''image2_test.gim''' is a dummy of 2 bytes filed with 2222 and the file '''image3_test.gim''' is a dummy of 3 bytes filed with 333333
