Change the world the client connects to

Here's how to set your client to automatically connect to the same world every time on Windows.

1. Click Start, and search:

   oldschool.prm

2. Right click the file and select 'Open file location'
3. Edit "oldschool.prm" in Notepad
4. Look for the line that says:

   Dcom.jagex.config=http://oldschool.runescape.com/k=3/l=$(Language:0)/jav_config.ws

5. Change the line to:

   Dcom.jagex.config=http://oldschool##.runescape.com/k=3/l=$(Language:0)/jav_config.ws

6. Replace ## with the world number minus 300 you'd like to connect to.  (e.g. to connect to world 306, you would replace the line with oldschool6 )
7. Save and close Notepad editor
