I've noticed, when I downloaded a PKG update for a game (fall out new vegas), and go into "Install packages" after putting the .pkg on my root drive on a USB, it installs, and if you go to "Game Utility" it says the updated version number, but when you go into the actualy game, the games version number dosen't change :/ It's like it's not even updating, I haven't tested it, but if you look at this post, I think it's the correct way of updating a game offline; Retail PS3 Updates? - PS3 NEWS - PlayStation 3 News - PS3 Forums I don't think updating retail packages are as easy as just plugging into into your USB and installing.
Is there something bugged with updater when it comes to old games? I have version 1.41 and can't download updates for Motorstorm1 BCUS98137 and Resistance1 BCUS98107. I know for a fact that both of these games have updates available.
