Here you will find Windows binary files of the most stable and feature-rich of each of the main re-recording emulators.

NES/Famicom - FCEUX version 2.1.0a
FCEUX merges elements from FCE Ultra, FCEU rerecording, FCEUXD, FCEUXDSP, and FCEU-mm into a single branch of FCEU. As the X implies, it is an all-encompassing FCEU emulator that gives the best of all worlds for the general player, the ROM-hacking community, and the Tool-Assisted Speedrun Community. This version includes Lua scripting (along with luabot) and the new .fm2 movie format, as well as all previous FCEU features. Download FCEUX 2.1.0a
