get_5018_data

Version	NID
3.60	0xBB70DDC0

This function copies first 0x20 bytes of the buffer of size 0x34 to destination.

Buffer is obtained with KIRK command 0x20

int get_5018_data(char* dest);

memcmp_5018_fast

Version	NID
3.60	0x22FD5D23

This function verifies that last 0x14 bytes of last response of size 0x34 from the game card (cmd56) are valid

CMD56 response is obtained with Buffer is obtained with KIRK command 0x20

For example it is called from sceAppMgrGameDataMount

int memcmp_5018_fast(char* in_data);

This is a timing safe memcmp. Xyz (talk) 10:02, 1 May 2017 (UTC)
