WebFritzi has announced that GUI64 v1.9 Preview is on the horizon, and it’s set to impress Commodore 64 enthusiasts who love mixing retro charm with modern usability. The new release introduces two editions: a classic Windows-style interface and a sleek new design inspired by the Macintosh aesthetic.
GUI64 is an open-source graphical user interface that runs on the Commodore 64, giving the machine a modern windowing experience without straying from its vintage personality. It lets users open, move, and resize windows while managing files through a mouse-driven interface reminiscent of early desktop systems.
This upcoming version builds on that foundation with improved visual consistency and smoother user interaction. The video demonstration showcases the new Mac-like theme in action, complete with rounded window corners, refined icons, and softer colors that make navigation more intuitive. The familiar Windows-style layout remains for users who prefer a more traditional setup.
The GUI64 v1.9 Preview also teases performance refinements under the hood. Faster screen updates, responsive mouse input, and better compatibility with disk drives give the interface a more polished feel. These subtle changes contribute to a cleaner and more responsive desktop experience while staying faithful to the Commodore 64’s character.
Whether you’re running GUI64 on real hardware or through an emulator, this update shows that even decades later, developers continue finding creative ways to extend what the C64 can do. WebFritzi’s dedication keeps the system relevant for both nostalgic users and new retro computing fans eager to see how far the classic machine can go.
Watch the video to see GUI64 v1.9 Preview in motion and witness how this familiar desktop takes on a whole new personality.
