RRT3SaveManager

A simple Avalonia-based save game manager for Railroad Tycoon 3 (RRT3).

Features

• Select and persist a save game folder (remembered across sessions)
• List .gmc save game files in the selected folder
• Rename save game files inline (double-click to edit, confirm/cancel)
• Duplicate save game files (automatically avoids name collisions)
• Delete save game files, with an animated drop-down confirmation dialog
• Fluent/Material icons for the UI via FluentIcons.Avalonia

Usage

1. Build and run:

   dotnet build
   dotnet run --project RailroadTycoon3SaveManager.Desktop

2. Select your save game folder using the browse button at the top.
3. Manage your save files:
   • Hover over a file to reveal the duplicate/delete buttons
   • Double-click a file to rename it
   • Use the check/cancel buttons to confirm or cancel renaming
   • Confirm deletion in the drop-down alert that appears

Requirements

• .NET 10.0 SDK or later
• Avalonia UI 11.x
• CommunityToolkit.Mvvm

Project Structure

This is split into a shared UI project and a desktop launcher:

• RailroadTycoon3SaveManager/ — Core Avalonia application project
  • App.axaml, App.axaml.cs — Application entry point and resources
  • ViewLocator.cs — MVVM view resolution
  • Views/ — Avalonia XAML views (MainWindow, SaveGameControl, DropDownAlert)
  • ViewModels/ — MVVM logic (MainViewModel, SaveGameViewModel)
  • Models/ — Data models (SaveGame)
  • Services/ — App settings persistence (AppSettings)
  • Helpers/ — Value converters (corner radius, path display formatting)
  • Assets/ — Icons and other resources
• RailroadTycoon3SaveManager.Desktop/ — Desktop entry point (Program.cs) and app manifest

Development

• All UI logic follows the MVVM pattern
• Uses ObservableCollection<SaveGameViewModel> for file lists
• Settings (last used save directory) are persisted as JSON via AppSettings
• Custom converters for conditional UI
• No automated test project currently exists
