Editing Talk:Resource Container (RCO)

==RCO versions (aka minFirmwareVer in rcomage)==
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

{{Boxcode|code=<syntaxhighlight lang="c">
		switch(rco->verId) {
			case 0x70: fputs("1.0", fp); break;
			case 0x71: fputs("1.5", fp); break;
			case 0x90: fputs("2.6", fp); break;
			case 0x95: fputs("2.7", fp); break;
			case 0x96: fputs("2.8", fp); break;
			case 0x100: fputs("3.5", fp); break;
			//case 0x107: fputs("ps3", fp); break;
			default: fprintf(fp, "unknownId0x%x", rco->verId);
		}
</syntaxhighlight>}}

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

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

Example... sysconf_plugin.rco from PS3 firmware 2.00 with version 0x106
{{Boxcode|code=<syntaxhighlight lang="xml">
<RcoFile UMDFlag="0" rcomageXmlVer="1.1" type="ps3" minFirmwareVer="unknownId0x106">
</syntaxhighlight>}}

==unknownByte==
In the xml representation of the .rco structure... every image inside the imagetree uses an unknown attribute named '''unknownByte'''. Is an attribute related with the image format and is equal to 0 in most of the PS3 images (very rarelly used)

*After searching in ALL the images contained inside ALL .rco files from firmware 4.76... there is a total of 72 images using '''unknownByte="1"''' (and 3098 images using '''unknownByte="0"''' for a total of 3170 images inside .rco's)
**7 images inside [[eula_net_plugin]].rco
**34 images inside [[newstore_plugin]].rco
**29 images inside [[regcam_plugin]].rco
**2 images inside [[system_plugin]].rco

from [[system_plugin]].rco
{{Boxcode|code=<syntaxhighlight lang="xml">
			<Image name="tex_optionmenu_bg" src=".\RCO 476 ofw\system_plugin\Images\tex_optionmenu_bg.gim" format="gim" compression="zlib" unknownByte="1" />
			<Image name="tex_optionmenu_base" src=".\RCO 476 ofw\system_plugin\Images\tex_optionmenu_base.gim" format="gim" compression="zlib" unknownByte="1" />
</syntaxhighlight>}}

*The 2 .gim files found using '''unknownByte="1"''' has some things in common:
**The size of both .gim file is exactlly 452KB (463.232 bytes)
**The resolution of both images in pixels is 512x206
**The first 0x80 bytes of the header in both is exactlly the same (see example below)

Is not specific for .GIM image format because other image formats uses it too, here are a couple of examples from newstore_plugin.rco where is used with .JPG and .PNG
{{Boxcode|code=<syntaxhighlight lang="xml">
			<Image name="BackGround" src=".\RCO 476 ofw\newstore_plugin\Images\BackGround.jpg" format="jpg" compression="uncompressed" unknownByte="1" />
			<Image name="ScrollButtonRich" src=".\RCO 476 ofw mod 5\newstore_plugin\Images\ScrollButtonRich.png" format="png" compression="uncompressed" unknownByte="1" />
</syntaxhighlight>}}

Is specific for PS3 (not used on PSP) as can be seen in the comments of the source code of rcomage [https://github.com/zingaburga/RCOMage/blob/master/src/rcofile.h here] in line number 188
 PS3 RCOs seem to have this extra element - probably something to do with planes/frames??

==UMDFlag==
This attribute was named UMDFlag unofficially because it was found used in the .rco files contained inside PSP UMD discs only

The name seems not accurate enought (because PS3 cant read UMD discs) so maybe is something more generic like "disc media", though never has been found a PS3 disc containing .rco's and the '''HYBRID_FLAG''' used in the bluray contents descriptor file [[PS3_DISC.SFB]] for "music bluray" and "photo bluray" are completlly speculative

*Speculation. Maybe is::
**0 = system rco
**1 = external rco (disc media, etc)

=Hashreports=
==PS3 rco's 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 rco's==
*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)

=Examples (rcomage builds)=
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 [https://www.youtube.com/watch?v=G4SuybRqji4 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)--[[User:Sandungas|Sandungas]] ([[User talk:Sandungas|talk]]) 18:48, 10 September 2016 (UTC)

==ImageTree with 1 image==
This is a basic example of how the files are stored inside the container, similar method is used for all files (images, models, sounds, and fonts ?)

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

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
