Hemulator vs higan

Hemulator is a free, open-source emulator for classic gaming systems on Linux, macOS, and Windows. The project lists 17 systems, with support at different stages of development. It detects ROM formats and system types automatically, and gives users five save-state slots for each game. Display settings include software and OpenGL-accelerated CRT effects such as scanlines and phosphor filters; audio playback is integrated through rodio. Users can adjust controls, window dimensions, video backend, and display filters. Headless command-line tools provide debug dumps, instruction tracing, logging, and benchmarking. The documentation also describes using these tools in CI/CD for automated testing and repeatable regression checks. Windows and Linux packages are listed, including 32-bit and 64-bit builds and Debian packages. Users must supply their own legally obtained ROM files; Hemulator does not include or distribute copyrighted game data. NES emulation supports 14 mappers, so games that rely on unsupported mappers will not work. The project directs users to GitHub bug reports, feature requests, and Discussions for help.

higan is a free, standalone multi-system emulator for Windows, macOS, Ubuntu Linux and FreeBSD. It focuses on accuracy, preservation and configurability, and emulates systems including Famicom, Super Famicom, Game Boy, Game Boy Color, Game Boy Advance, Mega Drive, PC Engine, MSX, ColecoVision, Neo Geo Pocket and WonderSwan. Official releases are available through the project’s GitHub releases page. Automated nightly builds are also listed for Windows, macOS, Ubuntu Linux and FreeBSD, but those builds are untested. The distribution includes icarus, a game library importer, along with the libco, nall, ruby and hiro components. The project was originally developed by Near. higan is free software under the GNU General Public License version 3 or a later version. The license states that the software comes without warranty. For community support, the project links to a discussion forum and a Discord chat. Its standalone format is listed as an emulation format, and the supported desktop systems include more than the general Linux, macOS and Windows platform listing.
