rcomage innacuracies, mistakes, bugs, or unsupported rco specifications

Rebuild verification

There is an easy way to verify if the building methods used by rcomage are exactlly like the ones used officially by sony, it basically consists in rebuilding an official rco, the hashes of the original and rebuilt .rco should match exactlly... in other words, after the rebuild the .rco file should be exactlly like the original

  • Requirements for this to work
    • the files needs to be extracted in "raw" format (if using "rcomage gui" in the DUMP tab uncheck all the checkboxes for GIM, VAG, VSMX)... long story short this is to avoid mistakes with the conversors
    • the rco TOC (aka what rcomage names "header compression") needs to use the same compression method than the original (if using "rcomage gui" in the COMPILE tab choose the correct "header compression" from NONE, ZLIB, RLZ)
      • rcomage doesnt keeps a record of this "header compression", so the way to identify it is by opening the original .rco in a hexeditor and check the value stored at absolute offset 0xC. See Resource Container (RCO)

This method is specially usefull with the .rco files that doesnt have "header compression" because is easyer to find the differences in a hexeditor, oldest PS3 firmware .rco's (like the ones in firmware 1.02) are not compressed

official dummy language string pointers not managed by rcomage

Found in xmb_plugin_normal.rco firmware 1.02 (and probably most others using language text strings, is just in this one is more obvious where the problem happens) 

illuminati event one, theory one (in the track)
-----------------------------------------------
<sandungas> just found an "innacuracy" of rcomage when rebuilding files
<sandungas> im not calling it a mistake because it doesnt breaks the format
<sandungas> is an (seems stupid) padding sony adds in the original files.... but rcomage doesnt
<sandungas> the point is maybe is not so stupid and is based on how the contents are mounted in the console ram, aligned to memory blocks and stuff like that
<sandungas> actually, maybe this is dependant of the console (ps3 or psp) because the different ram management, hmmmm
<zecoxao_> you need ZingaBurga
<sandungas> yep :/
<sandungas> and i remember him talking about this
<sandungas> someone asked him why the rebuilding was not perfect... and he mentioned some "weird" padding sony did but he could not understand why it happens
<sandungas> i think i know why :)
<sandungas> is a dirty trick, not efficient because adds padding, but assures you the text pointers are aligned properlly
<sandungas> something like this...
<sandungas> if total numer of languages inside .rco is not multiple of 4..... add "dummy" languages until it reaches a multiple of 4
  • xmb_plugin_normal.rco firmware 1.02 original and rebuild at absolute offset 0x50, is indicating the language pointers table starts at absolute offset 0x7EC
    • the size of this same table (indicated at offset 0x54) in original has a size of 0x90... and in rebuild 0x78 (after rebuild is smaller, rcomage has "lost" some bytes from it)

The table contains the pointers for every text string for every language, PS3 firmware 1.02 supports up to 10 languages, and every language contains 3 text strings... this makes a total of 30 pointers, every pointer is 4 bytes size, so the whole table of language text pointers should be 120 bytes length (0x78 in hex)... this is what rcomage does

But sony added 6 more pointers to the end of the table (of 4 bytes length each) all filled with zeroes... can be considered padding, but also can be considered "dummy pointers" because belongs to the table of pointers

Now... the question (and the reason why rcomage doesnt adds this pading) is.... why sony added that "dummy pointers" ?

  • It needs to be verifyed further in other .rco files but my theory is this: --Sandungas (talk) 00:56, 21 September 2016 (UTC)
    • the table of pointers needs to be aligned to 0x10 bytes boundary (from the start of the table itself), but trying to calculate the padding before building the file is a pita (because there can be lot of languages and lot of text strings for every language, is needed to read every text, multiply by language number, then calculate padding, etc... is not efficient)... so they decided to add this "blind alignment prevention". The thing consists in creating the table by cummulating "pointer placeholders" that contains ALWAYS groups of pointers that are a multiple of 4 based in the number of languages stored inside the .rco (this way the number of strings for every language doesnt matters at all, the table will always be aligned to 0x10 bytes)
    • As example, in the worst scenario posible... if the rco only contains one language, and only one text string for that language... at building time the table of pointers is created with a size of 0x10 bytes (to store 4 pointers for 4 languages minimal)... then the first pointer is filled... and because there are not more pointers to store the other areas are kept filled with zeroes
    • Another example, with 5 languages... the table is created for 8 languages (rounded to the next multiple of 4) so pointers are added to the table in groups of eight




  • There are other innacuracies when rebuilding this file... not sure if are related with text strings too though... are hard to see where is the problem because the areas are displaced by the problem explained above
    • as example... the last event in the "events table" in original is native:/Bar::onCursorMove (seems to be stored in a different order)

RCO format version 0x55 (used by PSP firmware 0.6.5)

PSP firmware 0.6.5 uses a primitive version of the rco format, this is an example of the rco header (first 0x94 bytes) of system_plugin.rco, most notable change is the header is smaller (so is missing some areas for features that was not implemented yet). I dont plan to look for all the changes but this little example hopefully will show what areas are missing to have an overall idea of the order of how features was implemented in the rco format. This version of the rco format is not compatible with rcomage... but it should by deleting the "unknowns" in the definitions of the source code (lines 51 and 76 of rcofile.h) then compile it (not tested, other errors can happen but this should work) the idea doesnt works, compiler returns other errors http://paste.ubuntu.com/23207840/

Original header (remember PSP uses little endian so some bytes are swapped)

objattribdef-ps3.ini

This file defines the names of the object attributes used in the XML descriptor at the root of the .rco

onInit, onPush, buttonPush, btnClick, onButton, onLoad... sometimes are used as a generic "run" command and can replace any of the other events (as example on some menues of xmb settings column when moving right is taken as a push) so is hard to identify the official name that are replacing. For this reason the list here keeps some counters of how many times have been found in official firmware. The counters works as a justification of why some names has been changed based in the number of times used

onPanelCommand seems to be an special event that can replace some of the standard events (used as a Button attribute)

Standard object attributes

onLoad           onInit <---------- used 5485 times in 4.76 firmware, most with "OnInit" or "nothing"
