Native macOS app for streaming, viewing, and controlling your Commodore 64 Ultimate device with real-time CRT shader effects.

Motion clarity CRT simulation using multi-stage Fibonacci-weighted exponential phosphor decay — an extended BFI approach with richer persistence curves than simple black frame techniques. Gamma-space processing, Voodoo2 16-bit quantization and Bayer dithering, adjustable scanlines. Optimized for consistent performance across hardware. MIT license.
