The Deep Dive: Mastering Nostale with a Packet Logger

How to use it

  1. Compile the code.
  2. Run the logger. It listens on 4006 (or whatever port you choose).
  3. Launch NosTale. You usually need to modify the shortcut target or use a loader to force the game to connect to 127.0.0.1 instead of the real server IP.
    • Example Argument: NostaleClientX.exe 127.0.0.1 4006
  4. The logger will intercept the traffic, allowing you to see packet IDs (like walk, attack, chat).

Option 1: Universal Sniffer + Script (For Experts)

Tools like Wireshark with custom Lua dissectors can work, but require heavy scripting. You would filter by UDP/TCP on port 4000, then manually decode the binary. Not recommended for beginners.

Prerequisites:

  • Windows 10/11.
  • Official Nostale client installed.
  • Administrator privileges.
  • Basic understanding of hex.

Decoding Nostale Packets (Example)

A known Nostale packet (login response): nostale packet logger

Hex: 0x01 0x00 0x0C 0x00 0x00 0x01 0x2A 0x00 0x00 0x00 0x00 0x00
Interpretation:
- Header: 0x01 (Login response)
- Length: 0x0C (12 bytes)
- Result: 0x00 (Success)
- Character slot count: 0x01
...

Community-maintained opcode lists exist for old Nostale versions (e.g., 0x03 = move, 0x05 = chat, 0x0E = attack). The Deep Dive: Mastering Nostale with a Packet
