You unpack the client .dat files using the Mppack program which can be found along with the public chapter 4 server files, it is also used to repack the client, however some servers have modified client encryption to stop you from using Mppack without some of their changes.

Hello friend. Can you please provide some detailed information about the techniques in your following post:


I'd like to know how did you open script.dat and got through it for questui.lua for it's editing possibility. What software have you used?

And how do you 'pack' it back so the game would start without any errors related to 'corrupted' .dat files.

Thank you in advance.
