Modding

From The Mythos Wiki

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.

Protected data

Specific files that can be extracted from the DAT archives are protected by SHA1 hash digests. These protected files are listed with the first 16 bytes of their associated hash digests in the ntlfl.cfg file located in the \data_mythos directory. These partial digests are verified against the remaining bytes stored on the server. Other files, which have the extension .cooked, cannot be viewed using any standard text editor.

You can verify the hash digests 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 digest in ntlfl.cfg. Mythos will start up, but the hash digest will be checked against the digest stored by the server. Mythos will automatically restart and ntlfl.cfg will be reset to the defaults.
