Step One:

To avoid server conflicts, delete everything inside your "C:\Program Files\Gravity\RO" folder EXCEPT "sdata.grf" and the "BGM" folder. If already have other servers downloaded and you skip this step then you will have problems so do not skip this step.

Step Two:

Download the ScytheRO Server Files and extract them to:
"C:\Program Files\Gravity\RO"

Download ScytheRO Server Files
ScytheRO Server Files include everything except "sdata.grf" and the "BGM" folder.
Requires WinRAR to Extract Files

Step Three (Optional):

In the newest version of Korean Sakray (0616 or later), there is a specific file.
"sdata.grf" - This is a very large (1GB+) file required to play any updated RO server.

If you do not have the newest version then you will not even be able to log in.
This file needs to be in the same folder as ScytheRO.
If you already have it, move it to C:\Program Files\Gravity\RO.
You probably will not have it so download from one of the following links:
