im not sure if rathena supported those client. also NEMO does not work on the older version of client. k3dt's diff patcher or ShinsDiffPatcher might work. it so hard to find diff patch of old client not.some of it is already patched and will work on specific old server emulator.
and also most of the important svn link is no longer working for older version of clients repo because it was already remove by assembla svn. that's why is so hard to find server and client files.
