ACF is a data structure stored in PS4 Kit System Flash at offset 0x1C9080.

ACF certainly stands for Activation Code/Control/Console File/Flag.

Structure[edit | edit source]

Total length is 0x68 bytes.

From	To	Description
1C9080	1C9083	Magic "acf\0"
1C9084	1C9087	Format Version Constant 4 bytes. (format_ver, format_minor_ver)
1C9088	1C9097	Activation Key
1C9098	1C909B	Issue Number. Ex: 3, 15.
1C909C	1C909F	Start Date 4 bytes. Little Endian.
1C90A0	1C90A3	Expire Date 4 bytes. Little Endian. Usually 90 days since Start Date.
1C90A4	1C90A7	Reserved Always zeroed.
1C90A8	1C90E7	Key_Hash Unique 64 bytes.

 typedef struct SceAcf {
     char magic[4];
     uint32_t format_ver;
     char activation_key[16];
     uint32_t issue_no; 
     uint32_t start_date;
     uint32_t expire_date;
     uint32_t reserved;
     char key_hash[64];
 } SceAcf;

Example[edit | edit source]

Structure and constant bytes are for every Dev / Test the same. Example:

Magic bytes: red.
Constant bytes: blue.
Unique bytes: green.

+ACF certainly stands for Activation Code/Control/Console File/Flag.
-There is a structure in it. It hase a Magic of 4 bytes, then there are constant 4 bytes following by unique changing 16 bytes. Then again constant 4 bytes following by unique 8 bytes and a third time, constant 4 bytes following by unique 64 bytes.
