1. Download cnc-ddraw.zip and extract it into your game folder
2. Start the game

Wine (Linux/macOS) only: override ddraw in winecfg manually or run cnc-ddraw config.exe once.

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: FunkyFr3sh#44

Some games may require additional steps before they can be used with cnc-ddraw, please check the 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.
