PS4 SLB PUP container format - SKFU

 /* file structure of SLB goes as following, if unpacking make sure you use 64 bits little endian on windows os */
 typedef unsigned char u8;
 typedef unsigned long int u32;
 typedef unsigned long long int u64;
 
 typedef struct{
 	u32 offset; //1 block is headersize (512 padded)
 	u32 cryptSize;
 	u64 reserved; //probably file alignment
 	u8 fileName[32];
 } fileEntry;

SLB PUP Files

These files are contained inside of SLB2 containers. They contain data pertaining to system firmware. All inner pup files begin with the same bytes:

Offset(h) 00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F
00000000  4F 15 3D 1D 00 01 01 12 04 00 00 00              O.=.........

After that the bytes begin to differentiate. It could be a file count, or a hash used later on to decrypt the inner pup files.
