Emu64 is an open-source Commodore 64 emulator for Windows and Linux, aimed at desktop users who want broad image-format support alongside developer-oriented tools. It provides C64 emulation with SDL2 audio and video output, Qt5 or Qt6 graphical interfaces, and support for D64, G64, CRT, TAP, T64 and PRG files. Its scope suits retro-computing users, software preservation work and developers examining Commodore 64 programs.

File and debugging support are the strongest parts of the package. Emu64 handles disk, cartridge and tape images, while its built-in debugger and disassembler provide tools for inspecting and working with software at a lower level. GeoRAM and REU memory expansion support adds further configuration for users interested in varied C64 memory setups. Audio can be configured with either the Emu64 or reSID engine, giving the emulator a choice of sound implementations rather than a single fixed option.

Platform fit is straightforward for desktop users: the project provides Windows binaries and a Linux AppImage, with SDL2 handling audio and video output and Qt providing the graphical interface. The project is distributed under GPLv2, which aligns with its open-source model but may not fit every proprietary distribution plan. Choose Emu64 if you want a C64-focused desktop emulator with extensive image handling and integrated debugging. Users seeking a broader range of Commodore variants or platforms beyond Windows and Linux should consider a different emulator.
