Setting up for private RO Server.
Ok this is how it is going to work.
You need to make a folder inside your current iRO folder called data.
In there you need to make a .xml file with the follow information in it.
Note: You can just rename a .txt to xml to change it to that.
<?xml version="1.0" encoding="euc-kr" ?>
<clientinfo>
<desc>Ragnarok Client Information - Taiwan Version</desc>
       <connection>
<display>saiRO</display>
<desc>None</desc>
<address>ip address</address>
<port>6900</port>
<version>18</version>
<langtype>1</langtype>
<registrationweb>http://ragnarok.gameflier.com</registrationweb>
</connection>
Then go to make a shortcut of your ragexe.exe file
And then go to properties and change it so it looks like so:
Gravity\RagnarokOnline\Ragexe.exe -1rag1
And then your done.
