This project is obsolete

AFAIK, no alternatives exists and I won't be maintaining this project anymore.

Some changes in the server code is required to make it work (confirmed 19/11/2024)

⚓ Belfast

Belfast is a private server reimplementation for the mobile game Azur Lane, written in Go using Gorm, HTMX, Hyperscript and Gofiber. Currently in early development, Belfast works on both iOS and Android without requiring jailbreak or root access, making it a tamper-free alternative to the official game server.

Warning

To bump the version of the game, you need to load the index of Belfast's web UI through a browser or curl.

Warning

Protobuf messages are not automatically updated. You need to update them manually, yet.

Important

Some packets have invalid / no names.

Tip

The import_pcap.py script can help you import packets from a pcap file into Belfast's dissection tool.

🌟 Features

Belfast currently has:

• A cool looking web UI to tinker easily with the game.
• A low-level multiplexed TCP server, which allows multiple connections at once.
• The ability of following game updates, along with importing ship, items, ... data automatically (US version).
• A small API that allows you to quickly implement new game messages without head scratching.
• A great dissection tool in which every packet is stored, along with a protobuf -> json deserializer (available in the web UI).

🌠 State

Belfast reimplements these features from the game:

• Custom server list
• Player bans
• Commander's dock (owned ships).
• Commander's depot (owned items).
• Build (you can start / end / edit builds).
• Resources (collection / consuming).
• Mails (along with custom sender, body, title, attachments, read / important states).
• Retire ships.
• Buying / equipping skins.
• Propose ships.
• Game's public chatroom.
• Secretaries (add, remove, moving is buggy but 'works').
• Lock / unlock ships.
• Rename proposed ships (features the 30d cooldown too).
• Custom notices
• Fleets management (add / remove / move ships & rename)

🚀 Roadmap

As I just started opening this project to the public I want to do these things:

1. Clean the code.
2. Refactor the web UI.
3. Add unit tests.
4. Create a repository for the Belfast's website in general.
5. Add a web UI tab for game's notices.

Before continuting the implementation of the game's protocol.

📦 Python requirements

To use the dissection tool (import_pcap.py), you need to install the following python dependencies:

• psycopg2
• scapy
• python-dotenv

⚠️ Note

While I'm proud about the progress made, I can't deny the code quality is less than ideal. This entire thing was hacked in over the course of just five days.

I initially had no plans to make this project public or open-source. It was simply a fun challenge that I undertook in my free time starting in December 2023. While the code quality may not be perfect, my hope is that it can serve as a starting point for others looking to get into Go development or explore Azur Lane's netcode. Let's see where this journey takes us!
