Skill by ara.so — Daily 2026 Skills collection.

What This Project Is

MinecraftConsoles is a C++ reimplementation/continuation of Minecraft Legacy Console Edition v1.6.0560.0 (TU19), targeting modern Windows (and unofficially macOS/Linux via Wine). Goals include:

• Multi-platform base for modding, backports, and LCE development

• Quality desktop experience with keyboard/mouse and controller support

• LAN multiplayer and dedicated server software

• Splitscreen multiplayer support

Repository: smartcmd/MinecraftConsoles

Primary language: C++

Build system: Visual Studio 2022 solution (.sln) + CMake support

Quick Start

Prerequisites

• Windows (primary supported platform)

• Visual Studio 2022 with C++ desktop workload

• Git

Clone

git clone https://github.com/smartcmd/MinecraftConsoles.git
cd MinecraftConsoles

Build with Visual Studio

• Open MinecraftConsoles.sln in Visual Studio 2022

• Set Startup Project to Minecraft.Client

• Set configuration to Debug (or Release), platform to Windows64

• Press F5 or Ctrl+F5 to build and run

Build with CMake (Windows x64)

# Configure
cmake -S . -B build -G "Visual Studio 17 2022" -A x64

# Build the client
cmake --build build --config Debug --target MinecraftClient

# Build the dedicated server
cmake --build build --config Debug --target MinecraftServer

See COMPILE.md in the repo for additional platform-specific notes.

LAN Multiplayer

LAN multiplayer works automatically on the Windows build:

• Hosting a world auto-advertises it on the local network

• Other players discover sessions via Join Game menu

• TCP port: 25565 (game connections)

• UDP port: 25566 (LAN discovery)

• Use the Add Server button to connect to known IPs

• Username changes are safe — keep uid.dat to preserve your data across renames

• Splitscreen players can join LAN/multiplayer sessions

Dedicated Server in Docker (Linux/Wine)

Recommended: Pull from GHCR (No Local Build)

# Start (pulls latest image automatically)
./start-dedicated-server.sh

# Start without pulling
./start-dedicated-server.sh --no-pull

# Equivalent manual command
docker compose -f docker-compose.dedicated-server.ghcr.yml up -d

Local Build Mode (Optional)

Requires a locally compiled Minecraft.Server.exe:

docker compose -f docker-compose.dedicated-server.yml up -d --build

Docker Persistent Volumes

Host Path Container Path Purpose

./server-data/server.properties /srv/mc/server.properties Server config

./server-data/GameHDD /srv/mc/Windows64/GameHDD World save data

Docker Environment Variables

Variable Default Description

XVFB_DISPLAY :99 Virtual display number

XVFB_SCREEN 64x64x16 Virtual screen size (tiny, Wine needs it)

Common C++ Patterns in This Codebase

Adding a New Key Binding (Keyboard Input)

The project added keyboard/mouse support on top of the original controller-only code. When extending input:

// Typical pattern for checking key state in the input handler
// Find the keyboard input processing file and add your key check:

bool isKeyPressed(int virtualKey) {
    return (GetAsyncKeyState(virtualKey) & 0x8000) != 0;
}

// Example: adding a new toggle key
if (isKeyPressed(VK_F7)) {
    // toggle your feature
    myFeatureEnabled = !myFeatureEnabled;
}

Registering a Launch Argument

Follow the existing -name / -fullscreen pattern:

// In the argument parsing section (typically in main or init):
for (int i = 1; i < argc; i++) {
    std::string arg = argv[i];

    if (arg == "-name" && i + 1 < argc) {
        username = argv[++i];
    }
    else if (arg == "-fullscreen") {
        launchFullscreen = true;
    }
    // Add your argument:
    else if (arg == "-myoption" && i + 1 < argc) {
        myOption = argv[++i];
    }
}

Reading server.properties

#include <fstream>
#include <sstream>
#include <map>
#include <string>

std::map<std::string, std::string> loadServerProperties(const std::string& path) {
    std::map<std::string, std::string> props;
    std::ifstream file(path);
    std::string line;

    while (std::getline(file, line)) {
        if (line.empty() || line[0] == '#') continue;
        auto eq = line.find('=');
        if (eq == std::string::npos) continue;
        std::string key = line.substr(0, eq);
        std::string val = line.substr(eq + 1);
        props[key] = val;
    }
    return props;
}

// Usage:
auto props = loadServerProperties("server.properties");
int port = std::stoi(props.count("server-port") ? props["server-port"] : "25565");
std::string serverName = props.count("server-name") ? props["server-name"] : "DedicatedServer";

Writing server.properties (Normalize / Auto-generate)

void writeServerProperties(const std::string& path,
                            const std::map<std::string, std::string>& props) {
    std::ofstream file(path);
    for (auto& [key, val] : props) {
        file << key << "=" << val << "\n";
    }
}

// Normalize level-id from level-name
std::string normalizeLevelId(const std::string& levelName) {
    std::string id = levelName;
    // Remove unsafe characters, lowercase, replace spaces with underscores
    for (char& c : id) {
        if (!std::isalnum(c) && c != '_' && c != '-') c = '_';
    }
    return id;
}

Troubleshooting

Build Fails: Missing Windows SDK

• Open Visual Studio Installer → Modify → add Windows 10/11 SDK

• Make sure the platform is set to Windows64 (not x86)

CMake Can't Find Visual Studio Generator

# Confirm VS 2022 is installed, then:
cmake -S . -B build -G "Visual Studio 17 2022" -A x64
# "17 2022" is the generator name for VS 2022

Game Launches But No Display / Crashes Immediately

• Ensure you're running from the directory containing all game assets

• Check that your GPU drivers support the required DirectX version

• Try Debug build for more verbose error output

Server Not Visible on LAN

• Check firewall rules allow TCP 25565 and UDP 25566

• Verify lan-advertise=true is NOT required for dedicated servers (it's for LAN broadcast; clients discover via Join Game)

• Ensure both client and server are on the same subnet

Docker Server: Wine Can't Display

• The XVFB_DISPLAY env var must match what Wine uses

• The container uses a minimal 64x64x16 virtual framebuffer — don't change this unless you have a reason

Username Reset / UID Issues

• Do not delete uid.dat — it stores your unique player ID

• If you rename yourself via -name or username.txt, your existing uid.dat keeps world data linked to your account

macOS / Linux (Wine)

• Download the Windows nightly .zip

• Run via wine Minecraft.Client.exe or CrossOver

• Stability issues (frametime pacing) are known and community-reported; not officially supported

Contributing

Read CONTRIBUTING.md before submitting PRs. Key points:

• Follow existing code style and naming conventions

• Console build compatibility should not be broken without discussion

• Security fixes are always welcome

• Check open issues (535+) for good first tasks

• Join the Discord for contributor discussion
