PSO2 Packet Library

GitHub crates.io docs.rs

Library that aims to provide easy(er) interaction with the PSO2 (Phantasy Star Online 2) protocol.

Targeted versions

  • Pre-NGS (Global: 6.1253.3, JP: 6.1201.0, Vita: 6.1001.2)
  • NGS

Compatability with other languages

This library has an FFI. It allows for working with packets using JSON or MessagePack.


  • Because a lot of information about the protocol is unknown, expect breaking changes (such as adding/deleting/renaming of struct's fields).
  • Any contributions are welcome (e.g. code style suggestions, comments, additional packet information, etc.)

Unless you explicitly state otherwise, any contribution intentionally submitted for inclusion in the work by you, as defined in the Apache-2.0 license, shall be dual licensed as above, without any additional terms or conditions.
