PUP are the file format of the PSP, PS3, PSVita and PS4 system firmware update packages.
They embed the OS, the syscon firmware, the WIFI, BT firmware, and on PS4 the EAP firmware.
PS4 PUP is special because it embeds single other PUPs.
PS4 PUP layout
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
}
