PUP

PUP (Playstation Update Package) is the file format of the PSP, PS3, PSVita and PS4 system software update packages.

PUP embed updates for devices such as the GameOS, Syscon, Wi-Fi, Bluetooth, Communication Processor, Southbridge, BD drive.

Structure

PS4 PUP is special because it embeds single other PUPs.

Header

Have a feeling the header for the new PS4 PUPs ends with a LZMA dictionary and file size… (ie a normal lzma header without the properties byte) anyone else done research into that? As in:

struct PUPPS4Header {
	uint32_t magic;			// PS4PUPMAGIC "\x4F\x15\x3D\x1D"
	uint16_t version;		// Big Endian (??)
	uint16_t unknownOne;
	uint16_t unknownTwo;
	uint16_t unknownThree;
	uint32_t dictSize;		// LE afaics
	uint32_t uncompressedSize;	// LE afaics
}

Tools

Decrypter (first step)

• ps4-pup_decrypt by idc

Unpacker (second step)

• ps4-pup-unpack by idc
• ps4-pup-unpacker by Zer0xFF (based on ps4-pup-unpack by idc)
