HalfNES is a free, open-source emulator for NES and Famicom software, aimed at users who want classic console support on Windows or Linux. It is distributed through a public GitHub repository, with Windows executables and Java JAR builds for other platforms. Its feature set covers core emulation needs while adding support for both NTSC and PAL system types, making it suitable for users focused on NES and Famicom compatibility rather than a broad multi-console front end.

For input and display, HalfNES offers remappable controls plus DirectInput and XInput joystick support. Full-screen mode, an NTSC display filter, and shader support provide additional presentation options. The emulator also includes an NSF music player, extending its use beyond game playback. Support for numerous NES mapper types and battery-backed game saves helps it accommodate cartridges that depend on different hardware mappings or persistent progress.

HalfNES is a strong fit for users who prioritize a free, open-source NES emulator with mapper support, PAL compatibility, controller flexibility, and straightforward display features. The main trade-off is the absence of save states, so users who rely on quick snapshots rather than battery-backed in-game saves should choose an alternative. Packaged versions require Java 8 or newer, and Windows and Linux are the explicitly named platforms, while other options depend on Java compatibility.
