RCO versioning
All RCO files contains a version number, the version increases with bigger firmwares but not always and is not directly associated with it. The same versioning sequence is used with rco's for PSP and PS3
It seems all the rco's of the same firmware shares the same version (speculative, not verifyed in all firmwares). Initially seems to be the version of the "rco set" or the version of the tool used to compile the whole "rco set" for a specific firmware
Is posible to create a correspondecy between the rco versions and the firmwares versions where it was used. RCOmage v1.1.1 (latest stable) identifyes the version based in a table with hardcoded values associated with a "system firmware version". The list was made for PSP and later was added the value 0x107 for PS3 (from an old ps3 firmware, newer firmwares has bigger versions)
Code Sample
After extracting the contents of the RCO with RCOmage, the version is stored for rebuilding purposes in the RCOXML descriptor file as minFirmwareVer
If the version is unknown, the version is stored as unknownId0x%x using unknownId to specify the fact that is unknown + the real value 0x%x in hex
Example... sysconf_plugin.rco from PS3 firmware 2.00 using version 0x106
Code Sample
Speculation
There is some formula to make a direct conversion from the hex value to the system firmware ?. I dont see it --Sandungas (talk) 15:19, 17 April 2015 (UTC)
PS3 RCO versions
If there is no formula, the only thing we can do is to make a list with the versions used in the "rco sets" from all PS3 firmwares. Probably this list will be included in the next version of rcomage to improve PS3 compatibility so please help completing the collection
| Console | "RCO set" version | System firmware version |
|---|---|---|
| PSP | 0x70 | 1.0 |
| PSP | 0x71 | 1.5 |
| PSP | 0x90 | 2.6 |
| PSP | 0x95 | 2.7 |
| PSP | 0x96 | 2.8 |
| PSP | 0x100 | 3.5 |
| PS3 | 0x106 | 2.00 |
| PS3 | 0x107 | ? |
| PS3 | 0x120 | ? |
| PS3 | 0x130 | 4.70 |
