sharpninja is an independent software publisher distributing open-source projects through its GitHub presence at https://github.com/sharpninja. The publisher's catalog currently contains one package, ViceSharp, a Commodore 64 emulator that is compatible with VICE, the widely established Versatile Commodore Emulator project. ViceSharp provides a graphical user interface built with Avalonia, the cross-platform .NET UI framework, which allows the emulator to run consistently across Windows, macOS, and Linux desktop environments. As an emulation product, ViceSharp falls into the software category of system emulators and retro computing tools, a segment that serves users who wish to run software originally written for classic 8-bit hardware on modern machines. Typical use cases include running vintage Commodore 64 games and applications, preserving and experiencing historical software, testing and debugging homebrew C64 programs during development, and supporting educational or hobbyist exploration of classic computing platforms. Because it is VICE-compatible, the emulator can leverage an established ecosystem of disk images, tape archives, and cartridge files, making it suitable for both casual retro gaming enthusiasts and developers who need a dependable emulation environment with a modern, accessible interface. The choice of Avalonia for the presentation layer reflects a contemporary .NET development approach, separating the user experience from the underlying emulation core while remaining portable across operating systems. As an open-source offering hosted on GitHub, the project also invites community inspection, contribution, and extension, aligning with the collaborative culture common in the emulation and retro computing communities.
