I saw this early today, but didn't consider it to be the answer as I thought it was just a way of downloading from the Sony servers, but using a PC instead of having to use the console. Is this not true? I ask, because the updates for these games were never on the Sony update servers, they were held on the online game servers hosted by the game manufacturers. Of course, these are now gone. So no more update downloads available. I own both these games, and when I put the disc in to the machine and search for updates, they come up with nothing, and that's as far as it goes. I have DLC for both these games, and again, they are useless and don't work without the necessary game update patch files from the online servers. Even the dualshock 3 joypads don't rumble without the game update patch files! Very frustrating!
I'll have a further look at what you've linked tonight, thank you.
