Lv1.self

From PS3 Developer wiki
Jump to navigation Jump to search

This is the Hypervisor (see Hypervisor Reverse Engineering) and follows the SELF file format.

Embedded Files Segment

lv1 contains many embedded selfs inside of a special segment "Embedded Files Segment". This is a segment within the program itself, loading in a hex editor gives a small file table which appears different from the others that sony has used.

File Table

The file table follows this structure

  • 4 bytes = number of entries
  • 4 bytes = table length

then the file table:

  • 4 bytes = index
  • 4 bytes = start
  • 4 bytes = length

then follows a null terminated string for each file commonly:

  • pme_init
  • sysmgr_ss.fself
  • pme_init.conf
  • ss_init.fself
  • updater_frontend.fself
  • ss_server1.fself
  • ss_server2.fself
  • ss_server3.fself


Files common on lv1

lv1.self delegates a lot of his work to the embedded selfs wich it loads to different process (see Hypervisor Reverse Engineering).

Dump lv1 embedded ELFs script

I did this script quickly to extract the embedded files within lv1. This script doesn't use the file table, is ugly, but works... anyone feel free to improve it --PsiCoLeO 16:11, 22 May 2011 (CDT)

How to use it

1) Save the script in a file named:

dump_lv1_embedded_files.sh

2) Give it execute permisions:

chmod +x dump_lv1_embedded_files.sh

3) Feed it with decrypted lv1.self:

./dump_lv1_embedded_files.sh lv1.elf
#!/bin/bash
# PsiCoLeO 2011
#
# Script to extract the embedded files from lv1.self
# There is no warranty that this script will work for you
# I can not be held responsable of what you do with this script or any damage you get from using it
# Use it as you please
