Download [cnc-ddraw.zip](https://github.com/FunkyFr3sh/cnc-ddraw/releases/latest/download/cnc-ddraw.zip) and extract it into your game folder 2. Start the game Wine (Linux/macOS) only: override `ddraw` in [winecfg](https://wiki.winehq.org/Winecfg#Libraries) If you use cnc-ddraw with a game that got its own windowed mode built in then **make sure you disable the games own windowed mode** first. You can enable windowed mode via cnc-ddraw config.exe instead. **If the game starts but it doesn't work perfectly** then open the config program and check the **Compatibility settings**. **cnc-ddraw does not support Direct3D/Glide**, it will only work with games that use a **DirectDraw (Software)** renderer. Usually you can tell by the look of the game if it's a 3D game or not, but you can also let cnc-ddraw generate a debug log and search for "IDirect3D" - Link: https://github.com/FunkyFr3sh/cnc-ddraw/issues/44 Some games may require additional steps before they can be used with cnc-ddraw, please check the [wiki](https://github.com/FunkyFr3sh/cnc-ddraw/wiki) for more details. **If the game doesn't start at all or it's crashing**, [then please generate a debug log file and upload it.](https://github.com/FunkyFr3sh/cnc-ddraw/issues/44) ### Hotkeys * [Alt] + [Enter] = Switch between windowed and fullscreen mode * [Ctrl] + [Tab] = Unlock cursor * [Right Alt] + [Right Ctrl] = Unlock cursor * [Alt] + [Page Down] = Maximize window ### Supported Games - Command & Conquer Gold - Command & Conquer: Red Alert - Command & Conquer: Tiberian Sun - Command & Conquer: Red Alert 2 - Captain Claw - Carmageddon - Carmageddon 2 - Warcraft 2 - StarCraft - Diablo - Diablo 2 - Age of Empires - Age of Empires II - Theme Hospital - Populous: The Beginning - Outlaws - Dungeon Keeper - Dark Reign: The Future of War - Star Wars: Galactic Battlegrounds - Atomic Bomberman - Dune 2000 - Oddworld: Abe's Oddysee - Commandos - Red Baron 3D - F-16 Multirole Fighter - F-22 Raptor - Nox - ...
