Replay Viewer

Drop in a .rrf recording and watch it play back on the real map, with the monsters, skills and damage numbers. Then save it as an MP4 to share.

CSV Encoder & Decoder

Client tables keep every cell as Base64. Drop the .csv here to read it in plain text, and drop it back when you are done to encode it again. Whole folders at once.

Programs you install on Windows. Each button opens the maker's own release page, so you get their build, not a copy of ours.

GRF Editor icon

GRF Editor

by Tokeiburu · free · Windows

Your Ragnarok client keeps everything in one big .grf file: every sprite, map, texture and sound. GRF Editor opens it.

What you can do with it

Look inside

Browse the archive like a folder and see every file your client uses.

Take things out

Pull out one sprite, one map, or a whole folder at a time.

Put your own in

Drop files in, save, and the client uses them. It can build a new .grf too.

Good to know. It also opens .gpf and .thor patch files, and it reads the newer kRO archive format that older tools refuse to touch. Who needs it: server owners, anyone editing a client, and anyone who is simply curious what is inside their own installation. We use it here as well. The official map layouts and the headgear sprites behind the in-game viewers on this site came out of a client with it.

Where these come from. Every Download button opens the maker's own release page. We do not repack anyone's software, so you always get the current build the way its author published it, and the download still counts for them.
