int sceSblAuthMgrCloseForKernel(int ctx);

sceSblAuthMgrStartForKernel

Version NID
0.931-0.990 0xCAA38DF7

Create SceSblAuthMgrZlibHeap.

int sceSblAuthMgrStartForKernel(void);

sceSblAuthMgrStopForKernel

Version NID
0.931-0.990 0x6C1F5048

int sceSblAuthMgrStopForKernel(void);

sceSblAuthMgrAuthHeaderForKernel

Version NID
0.931-3.60 0xF3411881

Issues F00D command 0x10001

SceSblSmCommContext130 type is defined in SceKernelModulemgr.

?Read caller SELF Info using sceKernelGetSelfAuthInfoForKernel? then writes it to context_130->caller_self_auth_info.

Calls smc_137 and smc_134 that interact with F00D. F00D set context_130->called_self_auth_info.

//ctx - obtained with sceSblAuthMgrOpenForKernel
int sceSblAuthMgrAuthHeaderForKernel(int ctx, const void *pSelfHeader, SceSize SelfHeaderSize, SceSblSmCommContext130 *ctx130);

sceSblAuthMgrSetupAuthSegmentForKernel

Temp name was sceSblAuthMgrLoadSelfSegmentForKernel, sceSblAuthMgrLoadSegmentForKernel.

Issues F00D command 0x20001

// ctx - obtained with sceSblAuthMgrOpenForKernel

0.931-1.50
int sceSblAuthMgrSetupAuthSegmentForKernel(int ctx, int segment_number, int segment_size, void output_buffer, int program_size);

3.60
int sceSblAuthMgrSetupAuthSegmentForKernel(int ctx, int segment_number);

sceSblAuthMgrAuthSegmentForKernel

Version NID
0.931-3.60 0xBC422443

Temp name was sceSblAuthMgrLoadSelfBlockForKernel, sceSblAuthMgrLoadBlockForKernel.

Issues F00D command 0x30001

// ctx - obtained with sceSblAuthMgrOpenForKernel
int sceSblAuthMgrAuthSegmentForKernel(int ctx, void *buffer, SceSize len);

sceSblAuthMgrLoadSegmentInternalForKernel

Version NID
0.990 0x15248FB4
// ctx - obtained with sceSblAuthMgrOpenForKernel
int sceSblAuthMgrLoadSegmentInternalForKernel(int ctx, int a2, unsigned int a3);

Issues F00D command 0x80001.

Spsfo (signed param.sfo) file is located in game cartridge at path gro0:gc/param.sfo. 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];
    uint64_t parent_authority_id; // ex: 0x2800000000000030
    uint64_t process_authority_id;
    char reserved[0x1C0];
} SceSpsfoHeader;
