Turn Your Phone Into Any Gaming Controller

Perfect For Multiple Use Cases

🔬 Kernel-Level Emulation via ViGEmBus

zController Desktop integrates with the ViGEmBus (Virtual Gamepad Emulation Bus) driver, which operates at the Windows kernel level. This sophisticated architecture allows zController to create virtual gaming controllers that are indistinguishable from physical hardware to the operating system. Unlike user-space solutions that may suffer from compatibility issues, kernel-level emulation ensures that games receive input through the exact same pathways as genuine controllers, guaranteeing 100% compatibility. ViGEmBus has become the industry standard for controller emulation, used by numerous professional gaming applications and recognized by the gaming community as the most reliable emulation framework available.

📡 Advanced Communication Protocols

Our custom communication stack is optimized for minimal latency and maximum reliability. WiFi mode utilizes UDP (User Datagram Protocol) for real-time input transmission, with packet prioritization ensuring controller inputs take precedence over other network traffic. The protocol includes error correction, automatic reconnection handling, and adaptive quality adjustment based on network conditions. USB mode leverages direct serial communication channels, bypassing network stack overhead entirely to achieve sub-5ms latency that rivals or exceeds wired controller performance. Both modes implement efficient data compression and batching algorithms to minimize bandwidth usage while maintaining responsiveness.

📱 Sensor Fusion Technology

Modern smartphones contain sophisticated sensor arrays including MEMS (Micro-Electro-Mechanical Systems) accelerometers and gyroscopes capable of detecting movements as subtle as 0.01 degrees. zController implements advanced sensor fusion algorithms that combine data from multiple sensors to create smooth, responsive motion control. Kalman filtering techniques reduce sensor noise and drift, while calibration algorithms ensure consistent behavior across different device models. This technology enables precise steering wheel simulation, accurate camera control in first-person games, and authentic Wii-style motion controls that rival or exceed original hardware responsiveness.

🔄 Real-Time Screen Sharing

zController's screen sharing feature utilizes efficient video compression and streaming protocols to deliver real-time PC screen mirroring to your phone. The implementation uses hardware-accelerated encoding when available, adaptive bitrate streaming based on connection quality, and intelligent frame skipping to maintain controller responsiveness even during intensive graphical scenes. This allows you to monitor gameplay, manage downloads, or control media playback from your phone while maintaining low-latency controller input simultaneously. The feature is particularly valuable for couch gaming setups where your PC monitor may not be easily visible.

🛡️ Security & Privacy

zController prioritizes user privacy and security. All communication occurs locally on your network - no data is transmitted to external servers. WiFi connections use your local network exclusively, and USB connections create direct point-to-point links. The application requires no special permissions beyond basic network access and USB debugging (for USB mode only). We maintain a strict no-telemetry policy, meaning your gaming habits, controller usage patterns, and personal information remain completely private. The open-source nature of the underlying ViGEmBus framework provides additional transparency and security assurance.
