Found in the System Flash on offset [http://www.psdevwiki.com/ps4/Flash-Main#0x1C9080_ACF_.28Dev.2FTest.29 0x1C9080] and only present on Dev / Test Dumps.
ACF is a data structure stored in PS4 Kit System Flash at offset [http://www.psdevwiki.com/ps4/Flash-Main#0x1C9080_ACF_.28Dev.2FTest.29 0x1C9080].


Total length = 0x68 ~= 104 bytes.
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.
See also [https://wiki.henkaku.xyz/vita/AFV PSVita equivalent].


Structure and constant bytes are for every Dev / Test the same. Example:
= Structure =
 
Magic Bytes == Red.
 
Constant Bytes == Blue.


Unique Bytes == Green.
Total length is 0x68 bytes.
