Well i made this tutorial so that i can help at this part of client side modification.I know those all that i write have been already said in forum but well i hope this is more compiled and it can help both new and old members.Anyway there it goes...

 

1) Download the DecPack from HERE

 

2) Patch the system with patcher

 

3) Now we will decrypt the desired file.Lets say for example systemmsg-e.dat

Opem cmd.exe and type: l2encdec.exe -s systemmsg-e.dat

 

and u will get this

Now u will have a file named dec-systemmsg-e

 

4) Delete the systemmsg-e.dat and rename the dec-systemmsg-e.dat to systemmsg-e.dat

 

5) Now from the following part there are 3 ways to decode/encode the dat files,the two are with L2clientdat and the other with L2asm/disasm

 

 

Way 1

 

We will do this with L2Clientdat_en or L2Clientdatfull (its the same thing)

 

a) Open the L2ClientDat_en (of the pack folder) and do Decode of systemmsg-e.dat.Now u will get a txt file with name systemmsg-e.

 

 

b) Open the txt and change whatever u want

c) Do your changes and save the txt

 

d) Open again L2ClientDat_en ,choose systemmsg-e and press encode

 

 

                              -----------------

Way 2

 

On way 2 we will use L2ClientDat.exe.

 

a) With the pack there are 2 folders with names "cn"and "en".There are the txt of some .dat files.Lets say u want to change something in the systemmsg-e.dat.

 

b) Open the txt inside the en folder and change the thing u want in the systemmsg-e.txt and save it

 

c) Open now the L2ClientDat.exe and choose from english the systemmsg-e.dat

 

 

d) Now press restore and u are done

 

                             ----------------------

Way 3

 

Now we will use l2asm/disasm

 

a) Open cmd.exe and type: l2disasm.exe -d c4\zonename-e.ddf zonename-e.dat zonename.txt   and u will get this

 

 

b) U will have now a txt with name zonename.txt.Open it and do the changes u want and save it

 

c) Now open cmd.exe and type this: l2asm.exe -d c4\zonename-e.ddf zonename.txt zonename-e.dat

 

 

                                ----------------------

 

6) Now time for the header.When u will have the encoded files (using one of the 3 ways) u open cmd.exe and type this: l2encdec.exe -h 413 systemmsg-e.dat

With this u will get a file named enc-systemmsg-e (.dat file) and its the one we want

 

7) Delete the systemmsg-e.dat file that u have and rename enc-systemmsg-e to systemmsg-e (it must be 33,9 kb)

 

Ok thats it you are done.With this way u can change whatever .dat,.ini,.int files (for the .ini or .int files u dont need to decode/encode just decrypt-change-encrypt)

 

Note:Some ppl say that for those -s doesnt work on decryption.Try -g

ermm...why not fileedit? :ooooo

yes fileedit is much easier way but thanks for other ways you mentioned.

Yeah fileedit,is easier,anyway you've done excellent work....I think that this should go Sticky..

 

 

*Webpage don't work*pls reupload it else..

nice i realy need this

man is that patcher create problem to gg like the other?

this very old very anyway is a nice share and your guide is very explained gj mate
