Download
Everything you need to play CirrusRO. Set them up in the order below.
1. CirrusRO Full Client
The client is a full folder, not an installer. Just download it and extract the folder anywhere (for example, your Desktop). There's nothing to install. Inside the folder you'll find two programs:
- CirrusRO Patcher: run this to update to the latest files. Run it first, and any time there's a new patch.
- CirrusRO: run this to launch the game directly.
2. Visual C++ Redistributable
A required Windows runtime. Install this if the client won't launch.
3. dgVoodoo
A graphics wrapper for newer Windows PCs that run on integrated graphics (iGPU) only, with no dedicated graphics card (Intel or AMD). On those machines the game can show graphical glitches or fail to render, and dgVoodoo fixes it. If your PC has a dedicated GPU, you can skip this.
Setup order
Extract the Full Client folder → install the VC++ Redistributable → apply dgVoodoo only if you're on an integrated-graphics (iGPU) machine (or get graphical glitches). Then run CirrusRO Patcher to update, and CirrusRO to play. See Getting Started for account registration.
