C64net review
A focused Windows emulator with core C64 hardware and D64 support.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
C64net is a C# implementation of a Commodore 64 emulator for Windows. It is aimed at users who want a basic way to emulate the Commodore 64 with core hardware coverage, keyboard and joystick input, D64 disk-image loading, and emulator-state saving. Its open-source model and free availability make it a straightforward option for Windows users who value access to the project and its implementation details.
The emulator's main strength is its coverage of fundamental C64 components. C64net includes cycle-based emulation, MOS 6502 and 6510 CPU emulation, VIC-II graphics emulation, CIA chip emulation, IEC serial-bus emulation, and 1541-II disk-drive emulation. This gives it a focused hardware-emulation scope rather than a broad platform ecosystem. Input support covers both keyboard and joystick control, while D64 loading addresses a central disk-image workflow. Saving and loading emulator state adds a practical way to resume sessions.
C64net is less suitable for users who need a complete feature set or broader compatibility. The project is described as abandoned, and SID audio, REU, and tape emulation remain incomplete. It also does not provide verified debugger, cartridge, or netplay features, and its platform support is limited to Windows. Choose C64net when free, open-source C64 emulation with core CPU, graphics, disk, and input support meets your needs. Choose an alternative if audio, tape handling, cartridge support, debugging, netplay, or another operating system is important.
