[HOW-TO] Work with Data.000

Ok, so below I will detail the retail method of patching the files (thanks for advice @ Dustin [Exiled] and Glandu2 for the righteous advice you guys so willingly give.)

1. Reading the Data.000

The structure of Data.000 is as follows:

Code:
public List<IndexList> IndexEntry = new List<IndexEntry>();

IndexEntry Class


2. Using the afore mentioned Data.000 structure you will simply use a binaryreader (c#) to load the data.000 file into a List<IndexEntry> of data000 entries

Load Class:


XOR Class


3. This will give you a List<dataIndexEntry> which you can the iterate through.
(You can tell if an incoming update is bigger by comparing update file size againt the data000_entry.size)
if the update file size > the data000_entry.size then you will append it's data.xxx file starting with the ending offset (see Update method for example)

Update Class


WriteFile Class


StringCipher Class


4. With the above Update method the data.xxx file will be updated appriopriately and a corrected Data.000 file will be returned (which you should then write to disk) [ The reverse of loading ]

Save Class


You now know how to update the clients data.xxx files EXACTLY as the retail launcher does (I won't explain the retail launcher as Glandu2 has done it before, just google it.)

Again I would just like to give a phenomenal thanks to c1ph3r and Pyrok and Glandu and Exiled for making this community better and helping me to be a better developer!

Coming soon a new Auth Emu by Glandu2 and I will explain in full the OTP Login process!
