Pixel Legacy on NixOS

This repository documents how to configure NixOS to connect to Pixel Legacy fan servers for Pixel Worlds.

Pixel Legacy is a community-run continuation of Pixel Worlds, hosted on custom servers. Connecting requires two changes to your system:

1. Redirecting specific game domains to the Pixel Legacy server IP.
2. Trusting the Pixel Legacy Root CA certificate so the game accepts the server’s HTTPS/TLS connections.

This README walks you through doing this the NixOS way — fully declarative, reproducible, and without running imperative scripts.

📋 Prerequisites

• A working NixOS installation
• Basic familiarity with editing configuration.nix and rebuilding your system
• The Pixel Legacy Root CA certificate file (rootCA.crt) from the Pixel Legacy setup files

🛠 Setup

1. Get the Pixel Legacy Root CA certificate

Download the certificate file (rootCA.crt) from the official Pixel Legacy Discord or website and place it in the same directory as your configuration.nix.

(rootCA.crt is inside "Pixel Legacy Automated For PC" -> "Install Pixel Legacy (Steam)" -> "Step 2" in the archive.)

2. Edit your NixOS configuration

Open /etc/nixos/configuration.nix (or the relevant module if using flakes) and add:

{
  networking.hosts = {
    "74.208.102.182" = [
      "lambda.us-east-1.amazonaws.com"
      "ec2-34-237-73-93.compute-1.amazonaws.com"
      "cognito-identity.us-east-1.amazonaws.com"
      "prod.gamev92.portalworldsgame.com"
    ];
  };

  security.pki.certificateFiles = [
    # rootCA.crt must be in the same folder as the configuration file containing these lines if you wish to copy and paste the configurations as is.
    ./rootCA.crt
  ];
  # Optional, most likely doesn't do anything except for creating an environment variable.
  environment.variables.PW_APPID = "636040";
}

TODO

• Putting this in a flake and writing an option to make it easy for others to use
