Yep - my original post is located here: http://www.ps3news.com/forums/ps3-gu...er-112443.html
It's a little outdated and I've learnt some new things - some of those 'ideas' are a little wrong - mainly the creation of the unique key [can't even remember the proper name for it lol]
But the hex editing it what you'll need to do. Changing the Game ID is a fairy simply method and looks to be the best bit. The other copy of info is probably over kill, but I wanted to make sure that people were hidden from Sony.
Using a PSN game or demo is best because they can be installed. As far as renaiming things - you can kinda do that - once you learn about the inner workings of a PKG file, you'll see images that could be replaced for your own. Just make sure that the Game ID is that off a game. The whole reason is to log that ID so that it looks legit and not LAUN12345
Also note - the tutorial is old and Mods might not want it to be re-opened, so if anyone has any troubles they can contact me here or email, or open a page in the help section. Best of luck.
