VirtualC64 for Mac

Overview — C64 on macOS

VirtualC64 brings the Commodore 64 to modern Mac computers by closely reproducing the original machine's behavior. This free emulator aims to provide an experience comparable to using real C64 hardware, letting users boot software, play legacy games, and run classic applications with high fidelity.

Emulation Accuracy

VirtualC64 models the internal timing and operations of the C64 down to individual clock cycles, which helps preserve the way software originally relied on hardware quirks. It reproduces the key subsystems — processor, video, and audio — so demos and games behave as intended.

Controls and Convenience Features

• Save and restore emulator states for quick resumption of sessions.
• Fully remappable input so you can customize keyboard and gamepad layouts.
• Multiple display modes and aspect options to match CRT look or modern screens.
• Simple file loading and library management for your C64 collection.

Supported Formats and Loading

• D64 and G64 images for disk archives.
• PRG files for single-program binaries.
• T64 tape collections and CRT cartridge images.
• Drag-and-drop loading plus a browser for organizing software.

Who will enjoy it

• Enthusiasts seeking faithful reproduction of old C64 behavior.
• Players who want to revisit classic titles on a Mac with modern conveniences.
• Developers and demo coders who depend on cycle-accurate timing.
