PlayStation 4's Operating System

Name: ORBIS OS
Based on: FreeBSD 9.0
Platform: 64 bits (x86_64)

Disc vs Download

PUP files on PS4 discs are 1GB, regardless of version, as they are zerofilled at the end of the file, just like PS3 PUP were zerofilled to 256MB. Hence, their hash will differ.

PS4 Playstation Update Packages links use the same structure as the PS Vita and PS3:

http://d<TLD>01.ps4.update.playstation.net/update/ps4/image/YYYY_MMDD>/pre_<md5>/PS4UPDATE.PUP?dest=<TLD>
(TLD=2 region letter abbreviation (jp,us,..), YYYY_MMDD is release date, md5 is 22-digits long HASH)

SLB2 structure

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 */
/* If you have any revisions, feel free to make them. ~Jakes625 */
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;

typedef struct{
	u32 magic; //SLB2
	u64 version; //1
	u32 fileCount;
	u32 blockCount;
	u8[12] reserved;
	fileEntry files[10];
} ps4pup;
