EMAX EMU: Custom Multiplayer System Development

Job ID: 39855449

Budget: €250 – €750 EUR

Hi there,

I’m looking to bring back online functionality for an old PC racing game that no longer has active servers. I would like to host a custom multiplayer environment under the name "EMAX EMU."

I already have VPS infrastructure and domain resources set up. I’m now seeking an experienced developer or team capable of analyzing game network behavior and building a compatible multiplayer system that allows players to connect, compete, and track progress.

Project Overview:

Analyze the game’s multiplayer protocol using network capture

Configure redirection of network traffic to a custom server

Develop a compatible backend system that enables online gameplay

Implement required client-side modifications (if needed) to support custom server communication

Build a web-based user registration and login panel

Users log in with a simple username and password

Create online leaderboards and lobby system

Support up to 25–50 concurrent users

Required Skills:

Network protocol analysis (e.g., with tools like Wireshark)

Experience working with online multiplayer systems

Proficiency in C/C++ or similar system-level languages

Understanding of low-level client/server communication

VPS setup, server configuration, and Linux environments

Web development (HTML/CSS/JS + backend language)

Experience with SQL-based databases (MySQL, PostgreSQL, etc.)

Deliverables:

A working multiplayer server environment that interfaces with the game

Web-based account system (register/login)

Lobby and leaderboard features

Deployment on VPS with basic documentation

Testing results (stability, user handling, etc.)

Payment Terms:

All payments will be processed via Freelancer milestone system.
I’m not offering any upfront payments before initial work demonstration.
A small, paid test task may be assigned to confirm technical ability.
Advance or bonus payments are possible once trust is established.
Only experienced and professional developers are encouraged to apply.
