Hemulator
What it is
Hemulator is free, MIT-licensed open-source software for emulating classic gaming systems on Linux, macOS, and Windows desktops. The project lists 17 systems, with support at different development stages. It identifies ROM formats and system types automatically and provides five save-state slots for each game. Display settings include software and OpenGL-accelerated CRT effects, including scanlines and phosphor filters, while integrated audio playback uses rodio. Players can customize controls, window dimensions, video backend, and display filters. Headless command-line tools provide debug dumps, instruction tracing, logging, and benchmarking, with documentation describing CI/CD use for automated testing and regression checks. Windows and Linux downloads include 32-bit and 64-bit packages plus Debian packages. Users must supply legally obtained ROM files because the project does not include or distribute copyrighted game data. NES emulation supports 14 mappers, so games requiring unsupported mappers will not work. Help is available through GitHub reports, feature requests, and Discussions.
