A lot of items which are used in the game of Spellborn are inside the packages.
The different allready give a hint which items are available, but basicly a package is just a file which can contain different assets (Items).
When items contain links to code inside other packages or even DLL or EXE files then you might get errors which can give strange behaviour of the game.
As far as I've seen the gameguard has no influence on the contents of the packages, it might just do a check if it's the correct content.
In other words if we're able to work around the gameguard protection we can use the latest version of the client and it's fixed networking code.
This might mean that we need to change some things in our current server code, but my guess is that no big changes have been made.
