With this module i released maybe yes for walker...
For the latest updated version it is immposible...
I looked in the Bot that server shares...there is a .exe file that is called loader
This files is inline Patching the L2Walker OOG and makes it able to connect to the server...but many functions are destroyed
I have the idea to edit this patcher they made and make it patch a Walker only for passing the Login and other functions stay intact...But there is no time for me to do this...i have to much work to do :-/
Mpj if you know people that know from assembly i am sure they can understand and help you make L2.NET connect to this Server normally
