Game data
You can find game data in the following directories:
\Program Files\Flagship Studios\Mythos\data_mythos(contains DAT archives)\Documents and Settings\Morgan\My Documents\My Games\Mythos(contains logs, settings, and local saves)
Unpacking the DAT files
Mythos DAT archives can be extracted using the UnHell command-line tool, which was originally developed for unpacking the DAT files for Hellgate: London.
To be safe, copy all of the .dat files (and their associated .idx files) you wish to extract into a separate folder before extracting.
Protected data
Specific files that can be extracted from the DAT archives are protected by SHA1 hash digests. These protected files are listed with their associated hash values in the ntlfl.cfg file located in the \data_mythos directory. Other files, which have the extension .cooked, cannot be viewed using any standard text editor.
You can verify the hash values of protected files using the Microsoft File Checksum Integrity Verifier command-line tool. You can also create your own hash digests with this tool; however, you cannot modify a protected file and the file's associated hash value in ntlfl.cfg. Mythos will start up, but the hash value will be checked against the value stored by the server. Mythos will automatically restart and ntlfl.cfg will be reset to the defaults.
