FCEUX Emulators #45 Emulators

FCEUX is an evolution of the original FCE Ultra emulator. Over time FCE Ultra had separated into many distinct branches. 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. 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 Tool-Assisted Speedrun Community.
