Some findings for PS4 PKG's and information i gathered around.
|
||||
|
||||
# PKG General Info
|
||||
|

|
||||
|
||||
A PS4 PKG looks like this:
|
||||
|
||||
|
||||
|
||||
First 4.096 bytes (0x1000) are the PKG Header. PKG header appears to be in Big Endian (like it was in ps3) although PS4 generally is a Small Endian machine.

# PKG File Table
|
||||
|
||||
The file table is a list of file entries. File entries start from **pkg_table_entry_offset** field of pkg header and it's increasing by 0x20 for each file entry . **pkg_table_entry_count** field of pkg header indicates the number of file entries. File Table values are **also Big Endian**
