## Overview

Eishockey Manager Redone is a C# recreation of a classic hockey-management game, using a user-supplied DOS game copy for original assets and data. A player configures a game, manages a club and roster, advances matchdays and seasons, and can follow optional live matches; results and state feed competitions and season progression. The desktop app hosts palette-based UI screens, while Core owns game rules and Formats reads legacy assets. README-documented save/load, audio, and emtool capabilities are included. Unsampled subsystems are represented at directory level; edges are limited to documented or indexed relationships.

Main entry points: [`src/EishockeyManager.Core/GameState.cs`](https://github.com/kaaasi/eishockey-manager-redone/blob/main/src/EishockeyManager.Core/GameState.cs) (Game state), [`src/EishockeyManager.Desktop/DesktopGame.cs`](https://github.com/kaaasi/eishockey-manager-redone/blob/main/src/EishockeyManager.Desktop/DesktopGame.cs) (Desktop host), [`src/EishockeyManager.UI/Screens`](https://github.com/kaaasi/eishockey-manager-redone/tree/main/src/EishockeyManager.UI/Screens) (Game screens), [`src/EishockeyManager.UI/Assets.cs`](https://github.com/kaaasi/eishockey-manager-redone/blob/main/src/EishockeyManager.UI/Assets.cs) (Asset loading)
