Replay

 is the name of the integrated recording feature designed for Ragnarok Online. It allows players to record gameplay sessions for the purpose of playback review or for submission to a publisher's support team for reporting ill-mannered behavior.

Recording
To access the feature, click on the  button in the game's UI menu.

Playback
To playback your files, initiate the RO launcher and select the  option instead of the regular client. Once you agree to the prompt that follows, the client will present you with a list of all your  files. All files must be located in the  folder in order to show up on this list.

To stop playing the file, click on the stop button and the client will reset the file back to the beginning. To switch to another file, click on the "Exit" button and it will return you back to the  list window.

Troubleshooting
If you are unable to load a file, it may be attributed to one of these issues:

Your client is outdated.
 * If your client is missing game assets (sprites, maps, audio, etc) that the has recorded, the file will be unable to load. Update your client to the latest patches to fix this.

The was recorded on a client with mods activated.
 * If someone recorded a file and add-ons were used during the recording, the  file won't load unless you have the same add-ons on your computer.

You're playing a file that was recorded on an illegal server.
 * Illegal servers run on different programming from official servers, therefore from illegal servers will be incompatible with official servers.
