Question about "*.ttarch2" file signatures
 

Hi all,

Does anyone know the significance of the different file signatures found in various ".ttarch2" archives? So far I've found "NCTT", "ECTT" & "ZCTT". I'm not sure if this is a feature present in more recent titles utilising the "Telltale Tool" engine, as so far I've only had a look at the title, "Batman: The Enemy Within". I've yet to test actually packing these archives as I'm unsure of whether the decryption has worked, as QuickBMS throws out a handful of errors, one of which being the lack of a "ECTT" file signature at the first 4 offsets, in most of the input archives.
