Connect C4 client to C6(IT) server

[Pandragon]

I am trying to use the IT branch to connect to C4 client.

I have bumped to this issue.
Almost all packets opcodes are easy to replace, but there are 2 files that confuse me and need help.

loginserver/serverpackets/Init.java
C4 http://svn.l2jserver.com/branches/L2_Ga ... /Init.java
IT http://svn.l2jserver.com/branches/L2_Ga ... /Init.java

loginserver/serverpackets/ServerList.java
C4 http://svn.l2jserver.com/branches/L2_Ga ... rList.java
IT http://svn.l2jserver.com/branches/L2_Ga ... rList.java
