# Marie's Wonderland

An open-source server implementation for mobile game NieR Reincarnation.

## Requirements

#### PC
- [.NET 10 SDK](https://dotnet.microsoft.com/download)
- [Visual Studio 2026](https://visualstudio.microsoft.com/downloads) or [Rider](https://www.jetbrains.com/rider/)
- [Android Platform Tools](https://developer.android.com/tools/releases/platform-tools) (`adb`)

#### Phone
- An Android device or an [Android Studio](https://developer.android.com/studio) emulator (physical device not required)

## Setup overview

### 1. Run the server
Open `MariesWonderland.slnx` and run the project.

The server listens on the standard HTTP and HTTPS ports on localhost:
- `http://localhost` (port 80) - used for HTTP asset serving
- `https://localhost` (port 443) - used for gRPC (HTTP/2)

### 2. Expose the server
The game communicates over gRPC (HTTP/2). You do not need ngrok or an external tunnel if your emulator or device can reach your machine directly.

- If running on an emulator: configure the emulator to reach the host (Android Studio emulators usually can reach the host).
- If running from a remote device or across a network: open ports 80 and 443 on your firewall/NAT and ensure those ports are forwarded to the machine running the server so the game can reach `http(s)://<your-host>`.

Ensure any network path supports HTTP/2 for gRPC traffic on port 443.

## Configuration
Server settings live in `src/appsettings.development.json`:

```json
{
  "Server": {
    "Paths": {
      "AssetDatabase": "<path to extracted asset revisions>",
      "MasterDatabase": "<path to extracted master data>",
      "ResourcesBaseUrl": "http://<your-host>/aaaaaaaaaaaaaaaaaaaaaaaa"
    },
    "Data": {
      "LatestMasterDataVersion": "1234567890",
      "UserDataPath": "Data/UserData"
    }
  }
}
```

- The `ResourcesBaseUrl` value must be exactly 43 characters long.
- If you change the length of that segment, you may also need to update the server-side minimal API that serves the short path (the `/aaaaaaaa...` handler) so its expected length matches your new value.
