    If we include console online, I'd like to see WKC servers up again.

    Also kinda wished I got back to POTC online before they shut down. Never get to know rest of story now.

    Part of the problem with trying to bring a game back online is when the traffic is encrypted. Let's say you had dumps of a game while it was online but the traffic was encrypted. Those packets are essentially garbage.

    Fragment was a little different in that it didn't use something like RSA (public/private key). If you take a look at the _00.elf you will find the encryption key in plain text. Having that and then figuring out how they did the encryption can make that a lot easier. Don't get me wrong, I am not saying it's easy, but having that information can make things easier.

    If you aren't able to do that your next bet is disabling the function that does the encrpytion / decryption of the packets on the client end. While this can work, the problem comes down to security and compatibility. If you are not able to restore the encryption to how it was now you have to issue a patch to all clients. On the pc this isn't an issue but for the ps2 you could be looking at something as simple as a codebreaker code or having to re-distribute patched ISO.

    The other problem (at least for ps2 games) is the fact that DNAS no longer exists. There is the packet replay server and that will get most games past DNAS but for any game that relied on DNAS for more than just authentication, you are out of luck. (I think there was only a handful of games that used it for more than that).
