I have a friend who has Koei games I want to extract models from, and offered to send me their game data off their PS3/PS4. Am I correct in telling them to make an ISO and send me that, or can they just send me whatever save data they have? What if they have DLC they want to send me; what formats would they have to use so that I received the correct data to extract?
They told me that ' Orochi doesnÔÇÖt have a System Data file that DW has. Just the Save Data.' But the save data is like 1MB, and I told them that's not what I needed...right? They were trying to transfer their data from their PS3 to their PS4 and something went wrong somehow...I don't know; I don't have a PS4 to know what they're going through.

But yeah, I really just want to tell them to make an ISO and send it to me. But I have no idea where installed game data is stored on PS3/4's and how they could bundle all that up and send it someone online.
