The '''[https://en.wikipedia.org/wiki/Nintendo_Entertainment_System Nintendo Entertainment System]''' (NES) is an 8-bit, third-generation console originally released as the '''Family Computer''' or '''Famicom''', in Japan, on July 15, 1983. The Famicom retailed for ¥14800. The console would be redesigned as the NES and released on October 18, 1985 in North America. The NES retailed for {{Inflation|USD|179.99|1985}}. It had a Ricoh 2A03 CPU at 1.79 MHz with 2 KBs of RAM.

The earliest games released on the Famicom suffered from significant hardware constraints due to the way the Famicom was designed: limited memory addressing (which meant games had a small maximum ROM size), how the graphics were loaded onscreen, just the native sound processing was available, no saving... To solve this problem, Nintendo came up with two solutions:

* The '''Family Computer Disk System''' (FDS). A Japan-only [[#Peripherals|add-on]] that played games from a semi-custom variant of Mitsumi's Quick Disk format. It offered slightly higher data storage and slightly enhanced sound processing. It also had a microphone never found anywhere else. There were plans to release it in the US; however, since the NES had its launch delayed to late 1985, and the mapper solution obsoleted it, the [[#Peripherals|add-on]] was never exported, and some of its exclusives were ported as regular cartridge releases.
* '''Memory Management Controllers''' (MMC), also known colloquially as '''[[#Mappers|mappers]]'''. They solved every aforementioned problem with bank switching for much more data, onboard FM audio chips, and much more. Most games released after 1986 that really pushed the system to its limits used mappers. A similar solution was used for the Game Boy.

Emulation for the Famicom/NES is robust, with many high-quality emulators for various systems and cycle-accurate emulation possible on even moderately powerful devices.

==Emulators==
Like for [[Game Boy/Game Boy Color emulators|Game Boy/Color]], tons of NES emulators exist. For a list of open-source projects, see this [https://github.com/search?utf8=%E2%9C%93&q=nes+emulator&type=Repositories GitHub query].

===Comparisons===
*[[Mesen|Mesen]] is a [[Emulation_accuracy|cycle-accurate]] NES emulator. Also, it is very user-friendly and supports lots of [[#Enhancements|enhancements]], [[#Peripherals|peripherals]], [[#Hardware_variants|variants]] and [[#Mappers|mappers]] that other emulators are missing. It also supports [[GoodTools|goodmerged]]. Latest versions require [https://dotnet.microsoft.com/en-us/download/dotnet .NET 6]. This is the most compatible NES emulator of the cycle-accurate variety.

*[[puNES]] is another [[Emulation_accuracy|cycle-accurate]] NES/FDS emulator. It is deemed as the second most compatible NES emulator of the cycle-accurate variety.

*[[Nestopia]] also is a [[Emulation_accuracy|cycle-accurate]] NES/FDS emulator. Nestopia has issues with [[Wikipedia:The_Young_Indiana_Jones_Chronicles_(video_game)|''The Young Indiana Jones Chronicles'']] and doesn't display the status bar in [[Wikipedia:Mickey%27s_Safari_in_Letterland|''Mickey's Safari in Letterland'']] correctly (among other problems). Nestopia Undead Edition is a fork of Nestopia meant to keep it alive and fix the aforementioned bugs. This version is generally recommended over vanilla. Even the libretro core for Nestopia is the Undead Edition.

*[[Nintendulator]] also is a [[Emulation_accuracy|cycle-accurate]] NES/FDS emulator. NintendulatorNRS is a fork of Nintendulator that supports the Famicom Disk System, rare mappers, VRT chipsets, and many unlicensed and bootleg carts and systems.

*[[FCEUX]] is a [[Emulation_accuracy|highly-accurate]] NES/FDS emulator and it supports lots of [[#Mappers|unlicensed mappers]], on top of this it's a [https://tasvideos.org/EmulatorResources recommended emulator on TAS Videos]. The New PPU implementation is more [[Emulation_accuracy|accurate]] than the Old PPU implementation. The emulator is very useful; thanks to its robust Lua scripting and incorporating FCEUmm into its feature set.

*BeesNES is aiming for [[Emulation_accuracy|subcycle accuracy]]. Currently it is a work-in-progress, but it is already including [[#Enhancements|enhancements]] like; [[NTSC_filters#NTSC-CRT_by_LMP88959_.28EMMIR.29|NTSC-CRT]], [https://github.com/L-Spiro/BeesNES#other-features debugger, disassembler, assembler and various TAS features].

*breakNES is aiming for [[Emulation_accuracy|gate-level accuracy]]. Currently it is work-in-progress and requires [https://dotnet.microsoft.com/en-us/download/dotnet .NET 6].

*MetalNES is aiming for [[Emulation_accuracy|transistor-level accuracy]], however it is currently work-in-progress.

*For official emulation, there is Nintendo's own [[Virtual Console]] or [[L-CLASSICS|Nintendo Switch Online]]. The Wii has a significantly larger library of NES games to choose from than the 3DS or Wii U, especially from third-party publishers.

There are many other NES emulators not listed here, as the NES has more emulators than any other system (new ones are started all the time). Only those that are well-known or stand out in some ways are covered here.

==Mappers==
A key difference between many emulators nowadays is how many mappers they support.
* '''No mapper:''' Supported on every emulator, even official Nintendo emulators.
* '''Official mappers''' (UNROM, AOROM, MMC1-6): Most emulators, as well as Nintendo's Virtual Console (but not their GBA emulators), will cover these.
* '''Third-party mappers''' (Various: e.g., Konami's VRC6/VRC7) While officially licensed by Nintendo, they were not allowed outside Japan. As a result, for their Western releases, many games that took advantage of their features (advanced ROM mapping, extra sound channels) were reprogrammed significantly and shipped on the official mappers, often with simplified soundtracks. A lot of fan emulators worth their salt will cover these. With those, you cover the entire officially licensed library.
* '''Unlicensed mappers:''' Mostly used by pirate cartridges, often long past the console's official commercial lifespan. Only the most active and recommended emulators will even bother covering them in a whack-a-mole quest for every new one discovered to this very day. If you're not interested in '''unlicensed''' Chinese or Russian bootlegs or newer unofficial NES demakes, it isn't a problem.

The NES ROM information isn't sufficient to describe the cartridge and emulate it, so emulators have to include the layout and behavior of these mappers in their code. At the same time, the ROM header tells the emulator which mapper to choose. So unlike with other consoles, no matter how accurate a given NES emulator will get, it will still never be able to run newly discovered ROM dumps from cartridges that used a so-far unknown mapper. Thus, Unlicensed NES support will be inevitably incomplete and a constant work-in-progress, hence claims some emulators are "inaccurate".

Related to this issue: This is why most emulators won't run unheadered NES ROMs. Newer versions of Nestopia can open those, but they're handled in a slightly different way: the information that would have been included in the iNES header is instead provided in emulator configuration files that get summoned as long as the ROM's hash matches exactly the No-Intro dump of that given game (which is inconvenient for ROM hacks).

==Peripherals==
There were many accessories released for the Famicom and NES but Emulation in General only covers accessories that are truly differentiated data streams from the basic controller. For example, the Power Glove is, in actuality, just a really complicated NES controller designed to convert motion into D-PAD, SELECT, START, A, and B button commands. The same goes for R.O.B. and his  ''Stack-up'' and ''Gyromite'' games because he was really just the second player. Strangely, the Famicom has a lot more peripheral hardware to emulate than the NES.<ref>[[Wikipedia:List of Nintendo Entertainment System accessories|List of Nintendo Entertainment System accessories]]</ref><ref>[https://problemkaputt.de/everynes.htm#controllers ProblemKaputt: NES controllers]</ref>

==Hardware variants==
===PlayChoice-10===
MAME is the only emulator that properly emulating the PlayChoice-10 system at the moment, [https://forums.nesdev.org/viewtopic.php?p=148572 most of the NES emulators only play the PlayChoice-10 games as a normal NES game].

===VS. System===
An arcade system based on the NES released for the US. It was released in two different cabinet variations: '''Vs. UniSystem''' and '''Vs. DualSystem'''. The latter has double chipsets on the PCB and is capable of handling two different programs or simply two separate copies of a single program simultaneously.

Most emulators support games in Vs. UniSystem cabinet by setting up different DIP switches. But only the MAME, [https://www.mesen.ca/docs/configuration/preferences.html#vs-dualsystem-settings Mesen], NintendulatorNRS, puNES and [https://nintaco.com/faq.html#VsDualSystem nintaco] are suitable for games in Vs. DualSystem cabinet. For commercial emulation, Hamster re-released several VS. System games from Nintendo and Konami as part of their ''Arcade Archives'' series (the former being exclusive to Nintendo Switch, the latter being also on PS4).

Since most VS. System games have palettes that differ from the standard RGB NES palette, ROMs made with VS. System, which are accidentally played in the emulator's NES mode (or vice-versa), will cause the colors to be totally garbled. This can occur when there is an issue with the emulator's configuration or the ROM's iNES header.

These emulators only supports UniSystem cabinet: [https://github.com/0ldsk00l/nestopia/blob/master/source/core/vssystem/NstVsSystem.cpp#L292 nestopia UE], [https://github.com/libretro/libretro-fceumm/blob/master/libretro/libretro.c#L1490 FCEumm] and [https://github.com/TASEmulators/fceux/blob/master/src/vsuni.cpp#L187 FCEUX], [https://tasvideos.org/Forum/Topics/17971?CurrentPage=9&Highlight=443471#443471 BizHawk], [[FinalBurn_Neo#List_of_emulated_systems|FinalBurn Neo]]

===Famicom Box===
Also re-released later as Sharp's FamicomStation. The hybrid NES/Famicom arcade box [http://famicomworld.com/system/other/famicombox/ Nintendo Famicom Box] is a bulky metal cube with a slot to insert money and secured with tons of locks. The hotel would set the amount of time you could play on one token and choose the available games. You can see it in action in season 18 of [http://www.gamingcx.com/ Game Center CX]. It was distributed in select hotels and stores and can hold up to 15 select Famicom releases at once. It had many more hardware lockout chips and pins with different behavior than usual (it also only supported cartridges using memory mapper 0). Sports a unique boot screen for both models released. 

Both the Famicombox and the Famicomstation are emulated by [[MAME]] and all of their games have been dumped

===Dendy===
A pirate NES Famicom clone that was sold in Russia and Eastern Europe, with the blueprint later reused for other Famiclones. Here's [http://www.youtube.com/watch?v=kne6AKyYUuM a link] to a CC-subtitled Kinaman video for more details. It's a very quirky NTSC NES optimized for 50 Hertz, with many other changes from the official PAL NES as well. Though these differences often break the compatibility of Dendy-specific releases on most emulators.

[[MAME]]/MESS supports this console, and some other emulators (such as Mesen, puNES, and FCEUX) have introduced support for it, as well as support for iNES 2.0 ROM headers (including the option to mark a ROM region as PAL Dendy). The cartridges themselves can still be played as long as the emulator supports broken carts.

===VTxx===
VTxx is a series of NOAC (Nintendo-On-A-Chip, a kind of chip that contains all the components of a Famicom/NES) chips that implemented multiple changes and enhancements compared to regular NES, manufactured by [http://www.vrt.com.tw/ V.R Technology].

Differences between VTxx series chips and regular NES could be checked on [https://www.nesdev.org/wiki/VTxx NesDev Wiki].

VTxx is often used in those low-quality, plug & play consoles or [[Wikipedia:Famiclone#Computer_type|keyboard-shaped]], so-called educational computers.

:V.R Technology provides an emulator called [http://www.vrt.com.tw/download.htm EmuVT] as official development & debugging tool, which supports the emulation of multiple kinds of VTxx series chips. It seems to be modded out of an old emulator called [https://web.archive.org/web/20110317151619/http://www.emulation9.com/nnnesterj/ NNNesterJ].

===NES Classic Edition===
{{main|wikipedia:NES Classic Edition}}
The NES Classic Edition is a mini console that emulates the experience of the Nintendo Entertainment System. It includes 30 classic NES games and is compatible with the Wii Classic Controller and NES Classic Edition controller.
Nintendo produced and sold about 2.3 million NES Classic Editions from November 2016 through April 2017, with shipments selling out nearly immediately. In April 2017, Nintendo announced they were discontinuing the product, leading to consumer confusion and incidents of greatly increased pricing among private sellers. Due to the demand for the NES Classic and the success of the Super NES Classic Edition console, Nintendo re-introduced the NES Classic on June 29, 2018. Production was discontinued again in December 2018.

==Emulation issues==
===QD FDS support===
Games dumped off the Famicom Disk System come into two major types:

* '''.fds format''': Most common format. Ubiquitous in ROM sets (GoodSets, No-Intro). Omits some checksum data.
* '''.qd format''' (stands for QuickDisk): Only ever used in official Nintendo re-releases. Almost identical to FDS, except QD is a full dump with checksum data. May omit padding.

The checksum data in question would be checked at BIOS startup to verify the integrity of the image and whether it was tampered with, in which case it will throw an anti-piracy error. [https://github.com/punesemu/puNES/releases/tag/v0.111 puNES added QD support in v0.111.] As of now, no other NES emulators support the alternate, more complete dumps and fudging that check's result to always return a negative. To emulate a .qd image with those, stripping the checksum data with a custom script is needed.

===Overscan===
{{Main|Overscan}}

[[File:Retroarch_2013-08-16_06-32-24-62.png|thumb|250px|Example of faulty visuals that are exposed when no overscan is cropped. Note the blank blue area to the left and the green garbage on the right. On NTSC CRT TVs, these areas may or may not be visible]]Several NES games need their overscan to be cropped to look proper. Unfortunately, there is no standard level of overcropping. Many games require different levels for the best results. For example, [https://en.wikipedia.org/wiki/Super_Mario_Bros._3 ''Super Mario Bros. 3''] requires quite a bit of cropping. However, the same level of cropping will obscure the letters of the status bar in [https://en.wikipedia.org/wiki/Castlevania#Games ''Castlevania''] games.

===Color palette===
{{Main|Famicom color palette}}

Unlike consoles such as the SNES, which natively generate their image in pure RGB, the Famicom normally generates and outputs an encoded NTSC video signal. This must then be decoded by the TV's built-in NTSC decoder, which means the resulting color palette often varies depending on the display's decoder. For this reason, NES games will appear to have different colors on different TV sets. To properly emulate this part of the NES experience, many Famicom emulators have a variety of different palettes to choose from.

The Wii and Wii U versions of [[Virtual Console]] use extremely dark color palettes. This is apparently not an accuracy issue, but rather an anti-epilepsy measure. For the Nintendo Switch Online service, the games were directly edited to remove seizure-inducing patterns, allowing it to use a normal palette.
