RCO versions

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

Code Sample

After extracting the contents of the RCO with RCOmage, the version is stored for rebuilding purposes in the RCOXML descriptor file as an attribute with the name minFirmwareVer

If the version is unknown is stored as unknownId0x%x using unknownId to specify the fact that is unknown + the real hex value 0x%x

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

Code Sample

Hashreports

PS3 all versions

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 6.61

  • 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)
  • Resurssiklunssi rebuilds the .rco files and allows for two rebuild modes:
    • TRIANGLE or CROSS - only rebuilds
      • The converted files will have minFirmwareVer="1.5" (the original value is lost in the conversion)
    • SQUARE or CIRCLE - rebuilds and recompress in ZLIB
      • The converted files will have minFirmwareVer="2.6" (the original value is lost in the conversion)
Code Sample
  • PSP 6.60 and 6.61 firmware. RCO hashes after resurssiklunssi rebuild (cross option)
Code Sample
  • PSP firmware 1.00 contains only 21 .rco files (all them uses ZLIB, none of them uses RLZ)
Code Sample

Examples

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

Also, i think rcomage has several problems (no offense intended is a great tool everybody loves) in how the areas of the structure are divided, some names that can be improved, some definition of lengths of partially known or unknown values, etc... the examples are going to look pretty similar to the examples i wrote at the bottom of CXML Containers page (the concept of how it works is the same)--Sandungas (talk) 18:48, 10 September 2016 (UTC)

ImageTree with 1 image

The .xml below is the RCOXML source file used to create the .rco. The file image_test.gim is a dummy of 16 bytes filed with 88888888888888888888888888888888
