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)
Unpacker (second step)
- ps4-pup-unpack by idc
- ps4-pup-unpacker by Zer0xFF (based on ps4-pup-unpack by idc)
