In other words, all the rco files updated in 4.89 are storing his values over line 2580 of the layout.txt files (and the other rco files not updated are storing his values before line 2580 in the layout.txt files), thats a rought identification of his location inside the layout.txt files but better this than nothing

===XMB layout references inside SPRX files===
In between firmwares 4.88 and 4.89 sony made some minor changes to the XMB that required to update the source code of a couple of sprx files and the content of his associated rco files to add a couple of [[RCOXML Objects]] in them. The new RCOXML objects added for 4.89 required to store 7 new values at line 2580 (from a total of 4602 lines) in the XMB layout files. The new values added at an intermediate position of the XMB layout files caused a displacement of +7 units in all the references to the values located after line 2580 of the layout files. As a consequence of that displacement it was needed to update 76 sprx files and 43 rco files to increase in +7 units the XMB layout references inside them. See: [[4.89_CEX#dev_flash|4.89 Changelog]]<br>
The way how works the XMB layout references inside rco files has been documented before, but the way how works inside the sprx files has been just an unproven theory since many time ago. This experiment is a sample of how it works, it throws an small ray of light at how the sprx files applyes "patches" over the [[RCOXML Objects]]<br>
The theory behind this experiment is based on the hipotesys that in between 4.88 and 4.99 there was maaaaany sprx files where the only thing that was updated in them is just a couple of bytes "here and there" that are the references to a line number of the XMB layout files, and the hipotesys that there are many times where the rco is storing the values inside the XMB layouts consecutivelly (so it could happen that the rco and the sprx could store all his values consecutivelly). So for this experiment it was needed to find a guinea pig where both, the sprx and the rco was updated in 4.89, also his function should be something trivial just to be sure sony was not trying to update anything important, and the last consideration was to find the files with the smallest size posible just to simplify the research with hexeditors/IDA... and the winner combos are... eula_hcopy_plugin.sprx (27 KB) / eula_hcopy_plugin.rco (60 KB)... and...  eula_cddb_plugin.sprx (29 KB) / eula_cddb_plugin.rco (125 KB)
The samples below are stripped versions from the main XML file generated by rcomage, where has been left only: the [[RCOXML Objects|RCOXML Object name]] (e.g: <IList>), the unique name (e.g: list_eula_start), and the attribute that difers in between 4.88 and 4.89 (the "overrides", responsibles of loading a value from a line of the XMB layout .txt files)
The references to the XMB layouts in the xml file generated by rcomage are in little endian, to convert them to "human readable" needs to be splitted in 2 chunks of 2 bytes each, first chunk is the "grid" and second chunk is the "factor". In this sample it can be seen how all the references to the "grid" was increased in +7 units
In the "human readable" conversion for rco values im adding a +1 because in code the first line of a .txt file is line 0, but in a text editor the first line is 1... so im guessing is also neeed to do this +1 addition in the values from the sprx<br>

From this behaviour in the order of how the values are stored in the XMB layouts we can deduce that "the sprx stores first" (and the slave rco stores last) but maybe this is just a coincidence and not an strict rule<br>

The description "Standard (NTSC)" and "Standard (PAL)" coud be confusing for someone (me included), but this paragraph from the user's guide indicates '''Standard (NTSC) is 480i''', and '''Standard (PAL) is 576i'''
The video resolution is selected in order of priority as follows: 1080p > 1080i > 720p > 480p/576p > Standard (NTSC:480i/PAL:576i).
So for clarification purposes this strings from inside sysconf_plugin.rco could be customized as:
<source lang="xml">
<Text name="msg_sd_ntsc">480i (Standard NTSC)</Text>
<Text name="msg_sd_pal">576i (Standard PAL)</Text>
</source>
==Coldboot script logic==
Inside the coldboot.raf there is a [[Coldboot.raf#Script | script]] that detects the current display resolution, and based on it applyes some transformations (scale and position) to the coldboot logos. In it can be seen how the PS3 XMB groups the ED and SD resolutions together<br>
The other video modes with a width different than 720 pixels doesnt falls into this "if-else" statements
*The screen resolution detection logic starts with the statement <code>if (System.resolution->0 == 720)</code>. It seems this includes all this video modes:
**576p and 576i (4:3 aspect ratio) '''720'''x576 (PAL anamorphic)
**480p and 480i (3:2 aspect ratio) '''720'''×480 (NTSC anamorphic)
*After that, the next logic stament is <code>if (camera.aspect == 4.0 / 3.0)</code>, this includes only:
**576p and 576i ('''4:3''' aspect ratio) '''720'''x576 (PAL anamorphic)
*Else is:
**480p and 480i ('''3:2''' aspect ratio) '''720'''×480 (NTSC anamorphic)
