I have created a packet editor specifically for Ragnarok since RPE and WPE is not working with protected Ro clients.
this program is a proxy instead that ro client connects to the Ro server it will connect to this program and all information sent by ro client will be forwarded to the ro server so, no need for injecting dll that may crash the client.
the program is 60% finish and its usable, the program uses vbscript to manipulate packets so anyone who is good with vbscrpt can help create a scrpt.
the normal filter is not finish and it doesn't support encrypted ro server yet.
I haven't try this in other RO server that's why I'm releasing it even though it's not yet finish
here's the link
video tutorial file:
to use the program you need a GRF editing tool that can be found here
working on servers:
if you download the program and it's working on your server post it so I could update the list of server.
