Introduction

OpenKore Packet Length Extractor is a program which generates recvpackets.txt for you. If you're having server problems, such as:

  • you get messages like "Unknown packet 022C",
  • after login you get disconnected after a few seconds,

then generating a new recvpackets.txt might solve the problem. This program is also compatible with VisualKore.

If you want to distribute this program to other people, please link to this page! Thank you.

I'm still having problems after using this program!

[edit]

What is recvpackets.txt?

The network data that the server sends to Kore, is a byte stream. Kore must be able to recognize messages inside that byte stream to be able to do something with it. But the size of the messages can vary from to server to server. Recvpackets.txt contains information about the size of each message, so Kore can correctly split the byte stream into messages. See also the detailed explanation.
