What puNES is
puNES is a Qt-based Nintendo Entertainment System emulator that also plays NSF, NSF2, and NSFe music files. It is available for Linux and Windows, with work-in-progress builds including a Linux x86_64 AppImage and 32-bit and 64-bit Windows versions for OpenGL or Direct3D 9. The project also documents compiling it for FreeBSD and OpenBSD. Listed capabilities include save states, rewind, shaders, and cheat support. Optional FFmpeg support enables audio and video recording, with formats including WAV, MP3, AAC, FLAC, MPEG, H.264, WebM, and AVI; recording may be disabled or unavailable with older FFmpeg versions. Portable mode can be set through a configuration file beside the executable, a special executable name, or a command-line option. The project describes its current executables as works in progress, so core changes may introduce bugs. It also warns that save states from version 0.110 or earlier do not work with current work-in-progress builds. puNES is free, with no free trial listed.
