What Hemulator is
Hemulator is a free, open-source desktop emulator for classic gaming systems, available for Linux, macOS, and Windows. The project lists 17 emulated systems, with support at different stages of development. It detects ROM formats and system types automatically and provides five save-state slots per game. Display options include software and OpenGL-accelerated CRT effects such as scanlines and phosphor filters, and audio playback is integrated through rodio. Users can configure controls, window dimensions, video backend, and display filters. Developers can use headless command-line tools for debug dumps, instruction tracing, logging, and benchmarking; the documentation also describes using them for automated testing and regression checks. Windows and Linux downloads include 32-bit and 64-bit builds and Debian packages. Users must provide their own legally obtained ROM files; the project does not include or distribute copyrighted game data. NES emulation supports 14 mappers, so games using unsupported mappers will not work. Help and community support are directed through GitHub bug reports, feature requests, and Discussions.
