Merge Data

A tool that patches custom data files into your Ragnarok Online client using a simple batch script.

How It Works

You place your chosen data files alongside your current roverse.grf inside the Tools/ folder, run a batch script, and it merges everything into a single patched roverse.grf ready to use in your game.

Prerequisites

  • Windows 10 or later
  • Ragnarok Online installed
  • Your roverse.grf from the Ragnarok game folder

Setup

Step 1 — Download & Extract Tools

Download the Tools package below and extract it. You will get a Tools/ folder containing all merge scripts.

Windows Security Warning Windows may flag this file as a threat. It is safe — click Keep to proceed.

Step 2 — Choose Your Data

Browse the available data packs in the table below. For each pack you want, right-click the .grf and .bat files → Download.

Step 3 — Prepare the Merge

Place all of the following inside the Tools/ folder:

  • The .grf file(s) you downloaded
  • The .bat file(s) you downloaded
  • roverse.grf copied from your Ragnarok game folder

Step 4 — Run the Script

Double-click the .bat file that matches your chosen data pack. Wait until the process reaches 100%.

If you selected multiple packs, run each .bat file one at a time.

Step 5 — Apply to Game

Copy the merged roverse.grf from Tools/ back into your Ragnarok game folder. You are done.
