Firmware Packages

File Header

All values are in big endian format.

 typedef struct {
   u32 0x00, 0x53434500// magic
   u32 0x04, 2		// version
   u16 0x08, 0		// sdk type?
   u16 0x0a, 3		// SCE header type; pkg
   u32 0x0c, 0		// meta offset
   u64 0x10,           // size of sce_hdr + sizeof meta_hdr
   u64 0x18, 0x80      // + content_size_real
 }


Game Packages

All game packages are signed with the ECDSA signature. The public key for it can be found in download_plugin.prx or in nas_plugin.prx (this also applies to NPDRM SELFs). Usually game packages are signed with two signatures - one for the header and the other for the entry table.

File Header

All values are in big endian format.

 typedef struct {
   u32 magic;
   u32 pkg_type;
   u32 pkg_info_offset;
   u32 pkg_info_size;
   u32 header_size;
   u32 item_count;
   u64 total_size;
   u64 data_offset;
   u64 data_size;
   char contentid[0x30];
   u8 digest[0x10];
   u8 k_licensee[0x10];
 } PKG_HEADER;
