NES Emulators for Retro Gaming: The Best

The world of retro gaming emulation is hard to navigate, but the best NES emulator holds the key to unlocking years of classic games.


Modern gaming hardware is very powerful. Lightning-fast SSDs and high-end GPUs with ray-tracing performance support the latest consoles and PCs. However, with all their hardware, these systems struggled to run games designed for older platforms. Other platforms just offer an extremely limited selection of retro games. That’s where emulators come in.

Instead of trying to use brute force to play retro games on modern hardware, programmers create programs that simulate conditions on older platforms. Colloquially known as emulators, these apps trick game ROMs into functioning properly. However, since different ROMs are designed for different hardware, there is no one-size-fits-all emulator. If you don’t have a suitable emulator, you won’t be able to play some ROMs. In fact, some emulators are designed for different users. Some are simple enough that anyone with a little computer skills can play, while others are designed for techies and can be modified to hell and back.


Because of these different design philosophies, some emulators are better than others. Even those trying to emulate some of the best NES games as “easy” might find that there’s a huge difference between a good NES emulator and one that technically works. That’s why here are the best emulators for anyone in the mood to play NES games.

How to use the NES emulator responsibly

Before continuing, you need to heed an important caveat: using an emulator falls into an ethical (and sometimes legal) gray area. The emulator itself is 100% legal. Heck, Nintendo uses Kachikachi and Canoe emulators for the NES and SNES Classic consoles. The only problem is that emulators are more or less digital consoles. An NES emulator without a ROM is as pointless as an NES without a game cartridge, and downloading ROMs from the internet is illegal.


The only legal way to get game ROMs is to use special tools like INLretro Dumper-Programmer to extract them from game cartridges you already own. If you plan to use any of the programs listed in this article, doing so legally will save you a lot of trouble. Also, this method ensures that you don’t have to worry about downloading malware-infected ROMs from shady websites.

Also note that each emulator works differently. If so, you should check the emulator’s terms of service and basic instructions before deciding to download and use the emulator. The more you know about the emulator you want to use, the happier you will be.


Most emulators only work with one type of game ROM. So if you like to play Sega Genesis games, you cannot use the Sega Genesis emulator you use to play NES games. Retroarch solves this little problem.

Retroarch is one of the only exceptions (if not) to the “no one-size-fits-all emulator” rule I mentioned earlier. This program is not so much an emulator as it is a front end for all your emulation needs. Retroarch does this by using different “cores” for different ROMs. For example, Retroarch can use the popular Dolphin core if you want to play Gamecube or Wii games. To play NES games, Retroarch uses Nestopia UE. However, you can choose the kernel you want from the emulator’s built-in online updater.

If Retroarch only offered an all-encompassing emulation service, that would still be enough to make it an emulator for most gamers, but it actually does much more than that. The program includes a built-in video recorder, analog shaders, how NES games look on different CRT TVs, and even auto-save states. Retroarch includes so many options and features that it’s almost impossible to provide comprehensive documentation on how to use it properly, which is the only downside of the emulator. However, if you’re willing to figure out a few things for yourself, this is a great option.


The purpose of most major emulators is to recreate the look, sound and feel of classic games. The closer an emulator gets to this goal, the more likely it is to be featured in the competition.

Mesen is widely regarded as one of the most accurate NES simulators. The program comes in two variants: Vanilla Mesen for NES games and Mesen-S for SNES, Game Boy and Game Boy Color games. Additionally, Mesen is compatible with over 290 games.

Like other emulators, Mesen offers a variety of additional features that players can use to optimize their experience. The emulator even comes with archives, video filters and built-in cheat codes. Additionally, if you’re looking to try “romhacking” (i.e. modifying the game) for the first time, Mesen includes a number of debugging tools that you can use to create your own custom titles. But unlike other emulators that have more options, Mesen is a breeze to download and set up. When you run the emulator for the first time, a handy configuration wizard runs to guide you through configuring controls and folder locations. It’s that easy.


Modern game consoles are designed to be zoneless. You can buy a PlayStation 5 game in Japan and it will run smoothly on a PS5 console you bought in the US. Knowing Japanese or not is another matter. Unfortunately, older consoles are less acceptable. For example, NES cartridges from European countries will not work on North American NES consoles. Fortunately, FCEUX did not encounter this problem.

FCEUX is arguably the closest thing to a truly versatile NES emulator. Unlike Retroarch (which “cheats” by using various emulators’ kernels), FCEUX supports all types of NES ROMs, including European PAL, US NTSC, and Famicom. However, all this dedicated support comes at a small price. Unlike Retroarch, FCEUX’s palette leaves a lot to be desired. The colors aren’t terrible, but they don’t match other emulators.

What FCEUX lacks in color accuracy, it makes up for in functionality. The emulator has all the bells and whistles that Mesen and Retroarch have, such as: B. Debugging and logging tools, but FCEUX also includes dedicated tools to aid speedrunning. Unlike other emulators, FCEUX even supports joysticks.

Nestopia UE

As mentioned, Retroarch uses Nestopia UE cores for NES ROMS. Of course, this fact makes you wonder how this emulator works on its own. Well, if the core of Nestopia UE sucked, gamers wouldn’t consider Retroarch one of the best emulators out there, would they?

Nestopia UE is an open source emulator written in C++ that supports NES and Famicom Disk System games. The program is fairly accurate in rendering and reproduction, and is easier to install and use than Retroarch. Since Retroarch uses Nestopia UE, if you only emulate NES games and want an experience comparable to Retroarch, simply download Nestopia UE to avoid the headaches of more complicated emulators.

In addition to being easy to install, everything gamers love about Retroarch is included in Nestopia UE. The emulator features auto-save, multiplayer online gaming, in-app recording, and a dedicated cheat dashboard. The only objective issue with Nestopia UE is the occasional drop in performance. The emulator has a small screen tearing issue that can be easily fixed by turning on VSync. However, when you turn on VSync, the game experiences input lag. This is where you choose your poison scene.

Nesbox Emulator

Before anyone can actually use an emulator, it usually has to be downloaded and set up. Depending on the emulator chosen, the process is not always easy. To make matters worse, you always run the risk of accidentally loading malware onto your computer. If only an emulator would allow you to play ROMs without additional installation. Fortunately there is.

The Nesbox emulator is a program that can be accessed through a browser. Just visit the emulator’s website, load the ROM and start playing, no downloads required. Well, that’s only half the story. You don’t need to download and install Nesbox, but you need to provide your own ROM via OneDrive. Fortunately, the emulator accepts NES, Sega, SNES and Game Boy ROMs.

Unfortunately, since the Nesbox emulator is a browser-based program, it offers a fairly simple experience. The emulator provides save state, local multiplayer, and gamepad or keyboard support, but that’s about it. Nesbox may be the least functional of any emulator out there, but it’s a small price to pay for its unparalleled accessibility.
