<p>FCEUX is a Nintendo Entertainment System (NES), Famicom, Famicom Disk System (FDS), and Dendy emulator. It supports NTSC (USA/JPN), PAL (European), and NTSC-PAL Hybrid modes. It supports both Windows and SDL versions for cross compatibility.</p>
<p>The FCEUX concept is that of an "all in one" emulator that offers accurate emulation and the best options for both casual play and a variety of more advanced emulator functions.
For pro users, FCEUX offers tools for debugging, rom-hacking, map making, Tool-assisted movies, and Lua scripting</p>
<p>FCEUX is an evolution of the original FCE Ultra emulator. Over time FCE Ultra had separated into many distinct branches.</p>
<p>The concept behind FCEUX is to merge elements from FCEU Ultra, FCEU rerecording, FCEUXD, FCEUXDSP, FCEUXDSP CE, and FCEU-mm into a single branch of FCEU.</p>
<p>As the X implies, it is an all-encompassing version of the FCEU emulator that provides the best of all worlds for the general player,
the ROM-hacking community, and the <ahref="http://tasvideos.org">Tool-Assisted Speedrun Community.</a></p>
