You’ve seen it. Maybe it was on an airplane, maybe it was at a friend’s house, but you saw people playing old Nintendo, Sega, or even PlayStation games on their computers. And yet, when you searched for those particular games in Steam, nothing comes up. What is this witchcraft?

What you saw, my friend, is called emulation. It’s by no means new, but you shouldn’t feel bad for not knowing about it. This isn’t exactly mainstream cultural knowledge, and can be a little confusing for beginners. Here’s how emulation works, and how to set it up on your Windows PC.

What Are Emulators and ROMs?

To play old school console games on your computer, you need two things: an emulator and a ROM.

The software mentioned above are only emulators and these don’t come with any type of games or software. You must own the game in order to play it with any one of the emulators. There are different ways of acquiring games, but we totally advise against any illegal means to acquire games or ROMs for such games.

• An emulator is a piece of software that mimics the hardware of an old-school console, giving your computer a way to open and run these classic games.
• A ROM is a ripped copy of the actual game cartridge or disc of yesterday.

So an emulator is a program you run, the ROM is the file you open with it. When you do, your computer will run that old school game.

Where do emulators come from? Generally, they’re built by fans. Sometimes it’s a single obsessive fan of a given console, and sometimes it’s an entire open source community. In almost all cases, though, these emulators are distributed for free online. Developers work hard to make their emulators as accurate as possible, meaning the experience of playing the game feels as much like playing on the original system as possible. There are several emulators out there for every retro gaming system you can imagine.

And where do ROMs come from? If a game comes on a DVD, like the PlayStation 2 or the Nintendo Wii, you can actually rip games yourself using a standard DVD drive to create ISO files. For old cartidge-based consoles, special pieces of hardware hardware makes it possible to copy games over to your computer. In theory, you could fill a collection this way. Basically no one does this, however, and instead downloads ROMs from a wide collection of websites that, for legal reasons, we will not be linking to. You’ll have to figure out how to get ROMs yourself.

Is downloading ROMs legal? We talked to a lawyer about this, actually. Broadly speaking, downloading a ROM for a game you do not own is not legal–just like downloading a pirated movie is not legal. Downloading a ROM for a game you do own, however, is hypothetically defensible–at least legally speaking. But there really isn’t caselaw here. What is clear is that it’s illegal for websites to be offering ROMs for the public to download, which is why such sites are frequently shut down.

The Best Starter Emulators for Windows Users

Now that you understand what emulation is, it’s time to get started setting up a console! But what software to use?

The absolute best emulator setup, in our humble opinion, is a program called RetroArch. RetroArch combines emulators for every retro system you can imagine, and gives you a beautiful leanback GUI for browsing your games.

The downside: it can be a little complicated to set up, especially for beginners. Don’t panic, though, because we have a complete guide to setting up RetroArch and an outline of RetroArch’s best advanced features. Follow those tutorials and you’ll have the best possible emulation setup in no time. (You might also check out this forum thread, which has great recommended settings for NES and SNES in RetroArch.)

Having said that, RetroArch might be overkill for you, particularly if you only care about one system or game. If you want to start with something a little bit simpler, here’s a quick list of our favorite easy-to-use emulators for all the major consoles since the late 1980s:

• NES (Nintendo Entertainment System): Nestopia is easy to use and will have your favorites running smoothly in no time.
• SNES (Super Nintendo Entertainment System): Snes9x is simple and decently accurate, and should run well on most systems. It should be noted there is heavy debate about which SNES emulator is truly best–but for beginners, Snes9x is going to be the most friendly.
• N64: Project64 is decently easy to use, depending on the game you want to play, though to this day Nintendo 64 emulation is full of glitches regardless of which emulator you use. This list of compatible games might help you find the right settings and plugins for the game you want to play (though once you get into tweaking Project64’s settings, it can become very complicated).
• Sega Genesis/CD/32X, etc: Kega Fusion runs all of your Genesis favorites, and all of those Sega CD and 32X games you never played as a kid because your dad didn’t want to spend money on peripherals he didn’t understand. It even runs Game Gear games as well.
• Game Boy: VBA-M runs Game Boy, Game Boy Color, and Game Boy Advanced games, all in one place. It’s simple to use and quite accurate.
• Nintendo DS: DeSmuME is probably your best bet, though at this point Nintendo DS emulation can be glitchy under even the best of circumstances. Touch controls are handled with the mouse.
• PlayStation: PCSX-Reloaded is the best-maintained PlayStation emulator. If you have a CD drive, it can run games directly from there, though ripped games typically load faster. Emulating PlayStation games can be very annoying, however, as every game requires settings tweaks in order to run properly. Here’s a list of compatible games and what settings you’ll need to change in order to run them.
• PlayStation 2: PCSX2 supports a surprising number of PlayStation 2 games, but is also quite annoying to configure. This probably isn’t for beginners. Here’s a list of compatible games and what settings you’ll need to change in order to run them.

Are these the best emulators for any given platform? No, largely because there is no such thing (outside RetroArch, which combines code from all these emulators and more). But if you’re new to emulation, these are all relatively straightforward to use, which is important for beginners. Give them a shot, then look up alternatives if you’re not satisfied.

If you’re a Mac user, you might want to try OpenEmu. It supports a ton of different systems and is actually pretty easy to use.

How to Use an Emulator to Play a Game

Every emulator outlined above is a little bit different, but serve one basic function: they let you load ROMs. Here’s a quick tour of how emulators work, using Snes9X as an example.

Emulators generally don’t come with installers, the way other Windows software does. Instead, these programs are portable, coming in a folder with everything that they need to run. You can put the folder wherever you want. Here’s how Snes9X looks when you download and unzip it:

Fire up the emulator by double-clicking the EXE file in Windows, and you’ll see an empty window. Here’s Snes9X:

Click File > Open and you can browse for your ROM file. Open it up and it will start running immediately.

You can start playing immediately. On most emulators, Alt+Enter will toggle full screen mode in Windows. You can customize the keys used to control the game, generally under the “Input” section of the menu.

You can even plug in a gamepad and configure it, if you have one. This USB SNES gamepad is cheap and great.

From there, you should be able to play your games without tweaking too much (depending on your emulator). But this is really just the beginning. Dive into the settings of any given emulator and you’ll find control over all sorts of things, from framerate to sound quality to things like color schemes and filters.

There is simply way too much variation between different emulators for me to cover all of that in this broad overview, but there are plenty of forums, guides, and wikis out there to help you along if you search Google. But once you get to the point of tweaking, we recommend checking out RetroArch, since it’s really the best overall setup. It may take a bit more work, but it’s a lot nicer than learning 10+ different systems once you get past the basics.

A video game console emulator is a type of emulator that allows a computing device^{[fn 1]} to emulate a video game console's hardware and play its games on the emulating platform. More often than not, emulators carry additional features that surpass the limitations of the original hardware, such as broader controller compatibility,^{[fn 2]}timescale control, greater performance, clearer quality, easier access to memory modifications (like GameShark), one-click cheat codes, and unlocking of gameplay features. Emulators are also a useful tool in the development process of homebrewdemos and the creation of new games for older, discontinued, or more rare consoles.

The code and data of a game are typically supplied to the emulator by means of a ROM file (a copy of game cartridge data) or an ISO image (a copy of optical media), which are created by either specialized tools for game cartridges, or regular optical drives reading the data.^[1] Most games retain their copyright despite the increasing time-span of the original system and products' discontinuation; this leaves regular consumers and emulation enthusiasts to resort to obtaining games freely across various internet sites rather than legitimately purchasing and ripping the contents (although for optical media, this is becoming popular for legitimate owners). As an alternative, specialized adapters such as the Retrode allow emulators to directly access the data on game cartridges without needing to copy it into a ROM image first.

History[edit]

By the mid-1990s, personal computers had progressed to the point where it was technically feasible to replicate the behavior of some of the earliest consoles entirely through software, and the first unauthorized, non-commercial console emulators began to appear. These early programs were often incomplete, only partially emulating a given system, resulting in defects. Few manufacturers published technical specifications for their hardware, which left programmers to deduce the exact workings of a console through reverse engineering. Nintendo's consoles tended to be the most commonly studied, for example the most advanced early emulators reproduced the workings of the Nintendo Entertainment System, the Super Nintendo Entertainment System, and the Game Boy. Programs like Marat Fayzullin's iNES, VirtualGameBoy, Pasofami (NES), Super Pasofami (SNES), and VSMC (SNES) were the most popular console emulators of this era. A curiosity was also Yuji Naka's unreleased NES emulator for the Genesis, possibly marking the first instance of a software emulator running on a console.^[2]

This rise in popularity opened the door to foreign video games, and exposed North American gamers to Nintendo's censorship policies. This rapid growth in the development of emulators in turn fed the growth of the ROM hacking and fan-translation. The release of projects such as RPGe's English language translation of Final Fantasy V drew even more users into the emulation scene.

Legal issues[edit]

Nes Roms

United States[edit]

As computers and global computer networks continued to advance and emulator developers grew more skilled in their work, the length of time between the commercial release of a console and its successful emulation began to shrink. Fifth generation consoles such as Nintendo 64, PlayStation and sixth generation handhelds, such as the Game Boy Advance, saw significant progress toward emulation during their production. This led to an effort by console manufacturers to stop unofficial emulation, but consistent failures such as Sega v. Accolade 977 F.2d 1510 (9th Cir. 1992), Sony Computer Entertainment, Inc. v. Connectix Corporation 203 F.3d 596 (2000), and Sony Computer Entertainment America v. Bleem 214 F.3d 1022 (2000),^[3] have had the opposite effect. According to all legal precedents, emulation is legal within the United States. However, unauthorized distribution of copyrighted code remains illegal, according to both country-specific copyright and international copyright law under the Berne Convention.^{[4][better source needed]} Accordingly, video game publishers and developers have taken legal action against websites that illegally redistribute their copyrighted software, successfully forcing sites to remove their titles^[5] or taking down the websites entirely.^[6]

Under United States law, obtaining a dumped copy of the original machine's BIOS is legal under the ruling Lewis Galoob Toys, Inc. v. Nintendo of America, Inc., 964 F.2d 965 (9th Cir. 1992) as fair use as long as the user obtained a legally purchased copy of the machine. To mitigate this however, several emulators for platforms such as Game Boy Advance are capable of running without a BIOS file, using high-level emulation to simulate BIOS subroutines at a slight cost in emulation accuracy.^{[citation needed]}

Impersonation by malware[edit]

Due to their popularity, emulators have also been a target of online scams in the form of trojan horse programs designed to mimic the appearance of a legitimate emulator, which are then promoted through spam, on YouTube and elsewhere.^[7] The Federal Trade Commission has since issued an advisory warning users to avoid downloading such software, in response to reports of a purported Nintendo Switch emulator released by various websites as a front for a survey scam.^[8]

Official use[edit]

Due to the high demand of playing old games on modern systems, consoles have begun incorporating emulation technology. The most notable of these is Nintendo's Virtual Console. Originally released for the Wii, but present on the 3DS and Wii U, Virtual Console uses software emulation to allow the purchasing and playing of games for old systems on this modern hardware. Though not all games are available, the Virtual Console has a large collection of games spanning a wide variety of consoles. The Virtual Console's library of past games currently consists of titles originating from the Nintendo Entertainment System, Super NES, Game Boy, Game Boy Color, Nintendo 64, Game Boy Advance, Nintendo DS, and Wii, as well as Sega's Master System and Genesis/Mega Drive, NEC's TurboGrafx-16, and SNK's Neo Geo. The service for the Wii also includes games for platforms that were known only in select regions, such as the Commodore 64 (Europe and North America) and MSX (Japan),^[9] as well as Virtual Console Arcade, which allows players to download video arcade games. Virtual Console titles have been downloaded over ten million times.^[10] Each game is distributed with a dedicated emulator tweaked to run the game as well as possible. However, it lacks the enhancements that unofficial emulators provide, and many titles are still unavailable.^[which?]

Until the 4.0.0 firmware update, the Nintendo Switchsystem software contained an embedded NES emulator, referred to internally as 'flog', running the game Golf (with motion controller support using Joy-Con). The Easter egg was believed to be a tribute to former Nintendo president Satoru Iwata, who died in 2015: the game was only accessible on July 11 (the date of his death), Golf was programmed by Iwata, and the game was activated by performing a gesture that Iwata had famously used during Nintendo's video presentations. It was suggested that the inclusion of Golf was intended as a digital form of omamori—a traditional form of Japanese amulets intended to provide luck or protection.^[11][12][13] As part of its Nintendo Switch Online subscription service, Nintendo subsequently released an app featuring an on-demand library of NES titles updated regularly.^[14] The app features similar features to Virtual Console titles, including save states, as well as a pixel scaler mode and an effect that simulates CRT television displays.^[15]

Due to differences in hardware, the Xbox 360 is not natively backwards compatible with original Xbox games.^{[fn 3]} However, Microsoft achieved backwards compatibility with popular titles through an emulator. On June 15, 2015, Microsoft announced the Xbox One would be backwards compatible with Xbox 360 through Emulation. In June 2017, they announced Xbox original titles would also be available for backwards compatibility through emulation, but because the Xbox original runs on the x86 architecture, CPU emulation is unnecessary, greatly improving performance. The PlayStation 3 uses software emulation to play original PlayStation titles, and the PlayStation Store sells games that run through an emulator within the machine. In the original Japanese and North American 60GB models, original PS2 hardware is present to run titles; however all PAL models, and later models released in Japan and North America removed some PS2 hardware components, replacing it with software emulation working alongside the video hardware to achieve partial hardware/software emulation.^[16][17] In later releases, backwards compatibility with PS2 titles was completely removed along with the PS2 graphics chip, and eventually Sony released PS2 titles with software emulation on the PlayStation Store.^[17]

Commercial developers have also used emulation as a means to repackage and reissue older games on newer consoles in retail releases. For example, Sega has created several collections of Sonic the Hedgehog games. Before the Virtual Console, Nintendo also used this tactic, such as Game Boy Advance re-releases of NES titles in the Classic NES Series.^{[citation needed]}

Other uses[edit]

Although the primary purpose of emulation is to make older video-games execute on newer systems, there are several advantages inherent in the extra flexibility of software emulation that were not possible on the original systems.

ROM hacking and modification[edit]

Disk image loading is a necessity for most console emulators, as most computing devices do not have the hardware required to run older console games directly from the physical game media itself. Even with optical media system emulators such as the PlayStation and PlayStation 2, attempting to run games from the actual disc may cause problems such as hangs and malfunction as PC optical drives are not designed to spin discs the way those consoles do.^{[citation needed]} This, however, has led to the advantage of it being far easier to modify the actual game's files contained within the game ROMs. Amateur programmers and gaming enthusiasts have produced translations of foreign games, rewritten dialogue within a game, applied fixes to bugs that were present in the original game, as well as updating old sports games with modern rosters. It is even possible to use high-resolution texture pack upgrades for 3-D games and sometimes 2-D if available and possible.^{[fn 4]}

Enhanced technical features[edit]

Software that emulates a console can be improved with additional capabilities that the original system did not have. These include Enhanced graphical capabilities, such as spatial anti-aliasing, upscaling of the framebuffer resolution to match high definition and even higher display resolutions, as well as anisotropic filtering (texture sharpening).

Emulation software may offer improved audio capabilities (e.g. decreased latency and better audio interpolation), enhanced save states (which allow the user to save a game at any point for debugging or re-try) and decreased boot and loading times. Some emulators feature an option to 'quickly' boot a game, bypassing the console manufacturer's original splash screens.

Furthermore, emulation software may offer online multiplayer functionality and the ability to speed up and slow down the emulation speed. This allows the user to fast-forward through unwanted cutscenes for example, or the ability to disable the framelimiter entirely (useful for benchmarking purposes).

Bypassing regional lockouts[edit]

Some consoles have a regional lockout, preventing the user from being able to play games outside of the designated game region. This can be considered a nuisance for console gamers as some games feature seemingly inexplicable localization differences between regions, such as differences in the time requirements for driving missions and license tests on Gran Turismo 4,^{[18][19][better source needed]} and the PAL version of Final Fantasy X requiring players to defeat almost impossible bosses in order to complete the game, as well as making it prohibitively expensive to purchase the character Yojimbo's 'Zanmato' move compared to the NTSC versions.^{[original research?]}

Although it is usually possible to modify the consoles themselves to bypass regional lockouts, console modifications can cause problems with screens not being displayed correctly and games running too fast or slow, due to the fact that the console itself may not be designed to output to the correct format for the game. These problems can be overcome on emulators, as they are usually designed with their own output modules, which can run both NTSC and PAL games without issue.^{[citation needed]}

Cheating and widescreen functionality[edit]

Many emulators, for example SNES9X,^[20] make it far easier to load console-based cheats, without requiring potentially expensive proprietary hardware devices such as those used by GameShark and Action Replay. Freeware tools allow codes given by such programs to be converted into code that can be read directly by the emulator's built-in cheating system, and even allow cheats to be toggled from the menu. The debugging tools featured in many emulators also aid gamers in creating their own such cheats. Similar systems can also be used to enable Widescreen Hacks for certain games, allowing the user to play games which were not originally intended for widescreen, without having to worry about aspect ratio distortion on widescreen monitors.
