Zinc64
Zinc64 is a free Commodore 64 emulator toolkit for Linux and Windows.
What Zinc64 is
Zinc64 is a free Commodore 64 emulator toolkit for Linux and Windows. It can be used as a standalone emulator or as a library for building emulators, and models PAL and NTSC C64 systems. Its emulated hardware includes the MOS 6510 CPU, MOS 6526 CIA, MOS 6581 SID, and MOS 6567/6569 VIC chipset, along with C64 devices and peripherals. Components can be replaced through a custom ChipFactory. The project lists cartridge, datassette, keyboard, and joystick support as done, as well as BIN, CRT, P00, PRG, and TAP formats. A remote debugger is available over telnet, and the README documents connecting radare2 through RAP server support. The zinc64-system crate can run without the Rust standard library in bare-metal environments. The project marks D64 and T64 formats, floppy and mouse support as not started; its Raspberry Pi 3 bare-metal port and OpenGL client are in progress. Building requires Rust and Cargo; Windows setup calls for Microsoft Visual C++ Build Tools 2017 with the Visual C++ build tools workload.
Good
- Runs as an emulator or an emulator-building library.
- Models PAL and NTSC C64 systems.
- Includes a telnet remote debugger.
- Supports BIN, CRT, P00, PRG, and TAP formats.
- Free under the GNU General Public License version 3.
Watch out
- D64 and T64 formats are not started.
- Floppy and mouse support are not started.
- Raspberry Pi 3 port and OpenGL client are in progress.
- Building requires Rust and Cargo.
Who it suits
Zinc64 suits users interested in running or building a C64 emulator who are comfortable building software with Rust and Cargo. Its component-swapping design may also suit people exploring emulator implementations.
Verdict
Zinc64 offers a free, extensible toolkit with a remote debugger and several listed C64 formats. Some formats and components remain unfinished, so check the status table against the features you need.
