Xml files have many uses.
My shortcut is named "Classical" and has the following Properties
Target: "C:\Games\Gravity\Ragnarok Online\clragexe.exe" 1rag1 /account:asdf.xml.
Start in: "C:\Games\Gravity\Ragnarok Online"
Shortcut Key: None
Run: Normal Window
the asdf.xml (or any other name you used) needs to have
<?xml version="1.0" encoding="euc-kr" ?>
Where the address & port are the same as the ones in your config.txt
This goes in your \data\ folder in the RO installation folder
When you start the shortcut, it will start RO using that address and port which is the one your kore will be emulating as.
