VirtualC64 turns an Apple Macintosh into a Commodore 64 emulator, supporting PAL and NTSC systems with emphasis on PAL accuracy and cycle-accurate emulation. It includes a built-in debugger and supports the PAL C64, NTSC C64, C64 II PAL, and C64 II NTSC variants. Media formats include D64, T64, PRG, P00, G64, TAP, and CRT. Joystick input can come from the keyboard or an external USB device; named options include Sony DualShock 4 controllers and the RetroFun! USB adapter for original Commodore joysticks. VirtualC64 is free and open source under the GNU General Public License, while its CPU core uses the MIT license. The core is designed for WebAssembly and can run in a browser, although macOS is the listed supported platform. On first launch, users are prompted to add four ROM images, which are not pre-installed because their copyright status is unclear. Recent versions include free ROM replacements from the Mega65 project, installable through the ROM configuration panel.
