FCEUltra is one of the top emulators for the classic 8bit Nintendo Entertainment System. It brings back some of the original games associated with the platform in a stunning color palette. Accuracy is extremely good, not to mention the overall gaming experience. Despite the ancient profile of original NES games, the platform is widely used by many gamers. It allows a deep customization, proper joystick support, great sound and even ICP/IP networking games for small groups of friends.
There are plenty of commands, keyboard combinations and shortcuts for gamers. At the same time, the emulator supports Windows and SDL versions for cross playing. Despite bringing back old games, the emulator is still being updated on a regular basis, so potential bug reports and suggestions are still being taken into consideration. The download is available for free, while professional users can also benefit from debugging features, map making or tool assisted movies.
