XRegistry.sys

Description

xRegistry.sys is the PS3 system registry, used to store settings, located in path /dev_flash2/etc/xRegistry.sys.

It holds settings such as PSN account details (user settings), devices attached to the Playstation (registered peripherals), the HDD model and serial number (console settings), etc...

Somes settings are sent to registered devices such a PSP (PSP/flash1/registry/).

Rebuild, regenerate, restore processes

The PS3 system always tryes to keep a record of everything that was made before (like the number of users that was created by storing his number in a cumulative counter that never decreases). For this reason when new info from another xregistry.sys needs to be added to the local xRegistry.sys the system does a selective "merging" of his values

This processes changes the values inside xRegistry.sys, but also can involve a whole rebuild of xRegistry.sys when new entries are added (like when going from 1.00 firmware to 4.66 firmware)

Backup copy

Backup located at /dev_flash2/etc/backup/xRegistry.sys

• Unknown purpose

Restore default settings

Some settings of xRegistry.sys (the ones that appears in XMB column) can de restored to his default values by rebooting the PS3 in Recovery Menu and using the option 2: Restore Default Settings

Backup and Restore from a HDD backup

When a HDD backup is restored some settings from the "source" xRegistry.sys (included in the HDD backup files) are not copyed in the xRegistry.sys of the "target" PS3, like the HDD model and serial

Regenerating a new xRegistry.sys

The option 5: Restore PS3 System (from Recovery Menu) doesnt cleans xRegistry.sys completly, some settings from the "old" xRegistry.sys are added in the "new" xRegistry.sys. One of the settings that are kept is the (annoying) user counter that never decreases, and some "trash" data from other previous erased users

• To kill the contents of xRegistry.sys eficiently the method depends of the flash type:
  • For NOR flash. xRegistry.sys is stored in VFLASH (a fake virtual flash stored in HDD)... by formatting the hdd in PC the xRegistry.sys is lost forever
  • For NAND flash. xRegistry.sys is stored in real FLASH... unknown kill method

Structure

Header

The header consists of a 0x10 bytes (seems to be static).

BC AD AD BC 00 00 00 90 00 00 00 02 BC AD AD BC

Offset	Length	Name	Example	Notes
0x0	0x4	header mark	BC AD AD BC
0x4	0x4	?	00 00 00 90	Unknown
0x8	0x4	?	00 00 00 02	Unknown
0xC	0x4	header mark	BC AD AD BC

Index Entries

Offset	Length	Name	Example	Notes
0x0	0x2	?	25 A0	Entry ID (?)
0x2	0x2	string length	00 20
0x4	0x1	string type	00	0 = Unlocked / In use 1 = Locked / Inactive 2 = Hidden / Never used 3 = Directory
0x5	variable	string	/setting/parental/passwordNumber
0x5 + string length	0x01	null	00	Separator

The last entry is marked with 0xAABBCCDDEE0000. This entry can also be used several times inside the table to mark a "break point" for some specials "subentries" (or subfolders)

• Notes
  • The entry 0xAABBCCDDEE0000 can be used inside the table to overwrite and old entry, the rests of the old entry are visibles after the seventh byte (etting... instead of /setting)... in the examples found seems to be related with the users that has been created/erased before... it can be an error of the process that updates the file, or maybe are the rests of groups of entries that was erased or disabled

Data Entries

The entry data begins at 0xFFF0. There is a 2 byte marker here (0x4D26) indicating it's the data section, continued by a table of data entries.

Offset	Length	Name	Example	Notes
0x0	0x2	?	00 00	Flags (?)
0x2	0x2	relative entry offset	00 86	+ 0x10 of the static header = absolute entry offset
0x4	0x2	?	81 2D	Entry ID (?) (isn't the same as file name entry id)
0x6	0x2	data length	00 04
0x8	0x1	data type	01	0 = boolean 1 = integer 2 = string
0x9	variable	data	00 00 55 53
0x9 + data length	0x1	null	00	Separator

The end of the table is marked with the entry 0xAABBCCDDEE0000. This entry can also be used several times inside the table to mark a "break point" for some specials "subentries" (or subfolders)

Settings

The settings are pretty cryptic in name, you might not notice anything after changing one. If you do notice a change please add to this table.
