Spsfo (signed param.sfo) file is located in game cartridge at path gro0:gc/param.sfo. It can also be loaded from host0: on DevKit. It has 3 parts: CF header and certification, plain SceSpsfoHeader and plain SFO (maybe reduced).

typedef struct SceSpsfoHeader { // size is 0x200 usually
    int version;                  // ex: 1
    SceSize size;                 // header size
    uint64_t system_version;      // ex: 0x0330000000000110
    char titleid[0x20];
