What It Does

1. Finds the game - Automatically searches Steam library folders
2. Downloads the mod - Fetches the latest release from GitHub
3. Installs MelonLoader - If not already installed (required for mods)
4. Installs mod files:
   • Main mod DLL to Mods/
   • UnityAccessibilityLib.dll to game root
   • UniversalSpeech.dll to game root
   • nvdaControllerClient.dll to game root
   • Localization data to UserData/ (if applicable)

Building

Requires .NET 8.0 SDK.

# Build
dotnet build -c Release

# Publish standalone executable
dotnet publish -c Release

The standalone executable will be in bin/Release/net8.0-windows/win-x64/publish/.

Adding New Games

To add support for a new game, create a new GameConfig entry in Games/GameConfigs.cs:

public static GameConfig NewGame { get; } = new GameConfig
{
    DisplayName = "Game Display Name",
    GameId = "shortid",
    SteamFolderName = "Steam Folder Name",
    ExecutableName = "Game.exe",
    GitHubOwner = "YourOrg",
    GitHubRepo = "RepoName",
    ModAssetPrefix = "ModZipPrefix",
    ModDllName = "YourMod.dll",
    HasDataFolder = false,
    UserDataSubfolder = null
};

Then add it to the All list in the same file.
