SLB2 structure
/* 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 long int u64;
typedef struct{
u32 offset; //1 block is headersize (512 padded)
u32 cryptSize;

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.
