Downloading ROMs is not legal in most circumstances. Under US copyright law, ROMs are protected software, and downloading them without authorization from the copyright holder is copyright infringement, regardless of whether you own the original game.
This surprises a lot of people. The retro gaming community has operated around ROM downloads for decades, and several persistent myths have made the practice feel normal and safe. The 24-hour rule is a myth. The “I own the game” defense is far weaker than most people think. And abandonware is not a real legal category.
This article gives you the full picture for 2026: what the law actually says, which exceptions are real versus invented, what the enforcement risk looks like for individual downloaders, and what happened when Nintendo went after ROM sites in court.
Is It Legal to Download ROMs
Downloading ROMs is not legal under US copyright law in the vast majority of cases. A ROM is a copy of a copyrighted software program, and distributing or reproducing that program without the copyright holder’s permission violates 17 U.S.C. Section 106.
Section 106 gives copyright holders the exclusive rights to reproduce, distribute, and create derivative works from their copyrighted material. When you download a ROM, you are creating an unauthorized reproduction of copyrighted software on your device. That is infringement under federal law.
The legal status does not depend on whether the game is old, out of print, or commercially unavailable. Copyright protection in the United States lasts for the life of the author plus 70 years for works created after 1978, or 95 years from publication for corporate-authored works. Most classic video games remain fully under copyright protection in 2026.
There are narrow exceptions that some people cite as justifications. None of them are as strong as the retro gaming community typically believes. Each is addressed in detail in the sections below.
Quick Facts:
- ROM downloading: illegal under 17 U.S.C. Section 106 in most cases
- Copyright duration for most classic games: 95 years from publication
- Games from the early 1980s: still fully under copyright in 2026
- Legal alternatives: official virtual console platforms, licensed retro compilations
- Enforcement against individual downloaders: rare but legally possible
Is It Illegal to Download ROMs
Yes, downloading ROMs is illegal under US copyright law. The download creates an unauthorized copy of copyrighted software, which is the definition of copyright infringement.
The illegality applies regardless of what country the ROM site is hosted in, regardless of whether you pay for the download, and regardless of whether the game is still sold commercially. Copyright law does not have a “practical availability” exception.
Some people point to the fact that ROM downloading is extremely common as evidence that it must be acceptable. Widespread behavior does not make something legal. Millions of people speed on highways daily. That does not make speeding legal. The same logic applies here: volume of infringement does not change the legal status of the act.
The practical enforcement picture for individual downloaders is different from the legal status, and those are two separate questions worth keeping distinct. The law says downloading ROMs is illegal. Whether you personally face consequences is a separate calculation involving enforcement priority, detection probability, and copyright holder resources.
| ROM Download Scenario | Legal Status | Notes |
|---|---|---|
| Downloading a game you never owned | Illegal | No ownership defense exists |
| Downloading a game you currently own | Illegal | Ownership does not authorize copying |
| Downloading from a foreign server | Illegal | US law applies to US users |
| Downloading a free ROM from a site | Illegal | No commercial exchange required for infringement |
| Downloading a ROM you personally ripped | Legally unclear | Ripping carries its own issues |
Are ROMs Illegal
ROMs themselves are not inherently illegal objects. The illegality arises from how they are obtained and distributed, not from their existence as a file format.
A ROM is simply a read-only memory image, a digital copy of a game’s data. ROM files are used legitimately in many contexts, including by game developers, preservationists working under specific legal frameworks, and researchers. The file format itself is neutral.
What makes a specific ROM illegal is whether it is an unauthorized copy of copyrighted software. If a game developer releases their own game as a free ROM download, that ROM is completely legal to download. If a copyright holder licenses their games to a platform that distributes ROM-based versions, those are legal copies.
The ROMs that the retro gaming community typically downloads are unauthorized copies of games whose copyrights are held by companies like Nintendo, Sega, Sony, Konami, Capcom, and others. Those companies have never authorized the distribution of their games through ROM download sites. That is what makes the typical downloaded ROM an infringing copy.
- ROMs as a file format: legally neutral
- Authorized ROM distributions: legal (official platforms, licensed compilations)
- Unauthorized ROM copies of copyrighted games: illegal under 17 U.S.C. Section 106
- ROMs of public domain games: legal to download
- ROMs created by independent developers: legal if no copyrighted material included
Key Takeaway: ROMs are not automatically illegal, but the ROMs available on typical download sites are unauthorized copies of copyrighted games, making downloading them a copyright infringement under federal law.
Is Downloading ROMs Illegal
Downloading ROMs is illegal for US users when the ROMs contain unauthorized copies of copyrighted video games, which describes the overwhelming majority of ROMs available on the internet.
The act of downloading creates a copy on your device. Under 17 U.S.C. Section 106(1), the copyright holder has the exclusive right to reproduce their work. Downloading without authorization infringes that exclusive right.
This is true even if the download is free. Copyright infringement does not require a financial transaction. You do not need to pay for something to infringe the copyright on it. Receiving an unauthorized copy, whether you paid for it or not, is infringement.
It is also true even if the website hosting the ROM is located outside the United States. US copyright law protects US copyright holders’ works globally. A US user downloading from a server in Eastern Europe is still infringing a US company’s copyright under US law. The server’s location affects where the site operator can be prosecuted, not whether the user’s download is infringement.
Key Takeaway: Downloading ROMs creates an unauthorized copy of copyrighted software on your device, which is copyright infringement under 17 U.S.C. Section 106 regardless of the source, the price, or the server location.
Are Emulators Legal
Emulators themselves are generally legal under US copyright law. The software that allows your computer or phone to run games from another system does not by itself infringe any copyright.
This was established through two major court cases. In Sega Enterprises Ltd. v. Accolade, Inc. in 1992, the Ninth Circuit ruled that reverse engineering a console’s software for compatibility purposes could qualify as fair use. In Sony Computer Entertainment v. Connectix Corp. in 2000, the Ninth Circuit ruled that Connectix’s Virtual Game Station emulator was a legal product, even though Connectix had to reverse-engineer Sony’s BIOS to build it.
These rulings established that emulation technology itself does not automatically infringe copyright. The emulator program runs the game. It does not contain the game’s copyrighted code. That distinction is legally significant.
What these rulings did not do is make ROM downloading legal. An emulator without a ROM is just software waiting for content. The legality of the emulator does not transfer to the legality of the ROM you load into it.
| Case | Year | Ruling | Impact on Emulator Legality |
|---|---|---|---|
| Sega v. Accolade | 1992 | Reverse engineering for compatibility can be fair use | Established legal basis for emulation research |
| Sony v. Connectix | 2000 | Emulator software is a legal product | Confirmed emulators themselves are legal |
| Nintendo v. RomUniverse | 2021 | ROM distribution is infringement | Confirmed ROMs separate from emulators |
Is It Illegal to Use an Emulator
Using an emulator is not illegal. Running emulator software on your device does not violate US copyright law.
The legal status of using an emulator depends on what you load into it. An emulator running legally obtained content, such as a game you purchased through an official platform or a ROM you legally ripped from a disc you own under the narrow conditions discussed below, is a legal use of software. An emulator running pirated ROMs downloaded from the internet is a different situation.
Think of it like a DVD player. The player itself is legal. Playing a legitimately purchased DVD is legal. Playing a pirated copy of a movie you burned from a downloaded file is not. The player does not determine the legality. The content does.
Some emulators have faced legal questions when they required BIOS files to operate that could only be obtained by copying them from original hardware, which raises a separate DMCA issue. That specific question is addressed later in the BIOS section.
Quick Facts:
- Emulator software itself: legal under US copyright law
- Using an emulator with legally obtained content: legal
- Using an emulator with pirated ROMs: copyright infringement
- Emulator legality established by: Sega v. Accolade (1992), Sony v. Connectix (2000)
- Downloading emulator software from official sources: legal
Is It Illegal to Download ROMs You Own
Downloading a ROM of a game you own is still illegal under current US copyright law. Ownership of the physical game does not give you the right to download a digital copy from an unauthorized source.
This is one of the most persistent myths in the ROM community. The argument goes: if you own the game, you should be allowed to have a digital copy for your own use. That logic is intuitive but legally incorrect.
Section 117 of the Copyright Act allows the owner of a copy of a computer program to make an archival copy for backup purposes. However, courts have interpreted this provision narrowly. The backup copy must be made by the owner from their own copy. Downloading someone else’s copy of the game from a ROM site, even if you own the original cartridge, does not qualify as a Section 117 backup copy.
The backup copy must be created by you from the copy you legally own. Downloading a pre-made ROM file from the internet does not fulfill that requirement, regardless of whether you own the original physical media.
- Section 117 backup copy right: applies only to copies you make yourself from your own copy
- Downloading a ROM of a game you own: does not qualify as a Section 117 backup
- What the law requires: making your own copy from your own authorized copy
- What the community does: downloading pre-made copies from unauthorized sites
- Legal status of downloading even if you own the game: still infringement
Is It Legal to Rip Your Own Game ROMs
Ripping a ROM from a game cartridge or disc you legally own is legally murky and carries its own risks, particularly when the game includes technological protection measures.
Section 117 of the Copyright Act does provide a narrow right to make a backup copy of a computer program you own. If a game is stored on media without any digital rights management or copy protection, and you create a copy for your own archival use without distributing it, you have the strongest argument for legality under Section 117.
The problem is that most modern and even many older game cartridges include technological protection measures, and the DMCA’s anti-circumvention provisions under 17 U.S.C. Section 1201 make it illegal to circumvent those measures even for personal backup purposes. Circumventing copy protection to rip a ROM likely violates the DMCA regardless of your ownership of the physical cartridge.
Additionally, Section 117’s backup copy right has been interpreted to apply to software you use on a computer in its original sense. Courts have not clearly extended it to cover video game cartridges and the specific hardware needed to rip them.
| Ripping Scenario | Legal Assessment | Key Law |
|---|---|---|
| Ripping unprotected cartridge for personal backup | Strongest legal argument | 17 U.S.C. Section 117 |
| Ripping a cartridge with copy protection | Likely illegal | 17 U.S.C. Section 1201 (DMCA) |
| Distributing your own ripped ROM | Illegal | 17 U.S.C. Section 106 |
| Ripping a disc with DRM | Likely illegal | DMCA anti-circumvention |
| Using third-party ROM ripping hardware | Varies; circumvention issues apply | 17 U.S.C. Section 1201 |
Is Abandonware Legal
Abandonware is not a recognized legal category under US copyright law. A game being “abandoned” by its publisher does not affect its copyright status or make downloading unauthorized copies legal.
The term “abandonware” refers to software that is no longer commercially sold or supported by its original publisher. The retro gaming community uses it to describe old games that seem impossible to obtain through legitimate means. The concept is compelling. The legal reality is that it provides no actual protection.
Copyright protection continues whether or not the copyright holder actively sells or supports the work. A publisher that shut down in 1995 still holds valid copyrights on its games, or those copyrights passed to its successor company, were acquired in a bankruptcy sale, or are held by a parent company. The commercial unavailability of a game does not put it in the public domain.
Some truly old games, those published before January 1, 1928, have entered the public domain and can be legally copied and distributed. Games from the 1980s, 1990s, and later remain fully under copyright in 2026. No Atari, NES, SNES, Genesis, or PlayStation-era game has entered the public domain yet.
Key Takeaway: Abandonware is not a legal concept. Commercial unavailability does not affect copyright status, and no video game from the classic retro gaming era has entered the public domain as of 2026.
Is It Illegal to Download BIOS Files for Emulators
Downloading BIOS files for emulators is generally illegal under the DMCA. BIOS files are firmware, copyrighted software owned by the console manufacturer, and downloading them from unauthorized sources is copyright infringement.
Many emulators require a BIOS file extracted from original hardware to function accurately. The PlayStation BIOS, for example, is copyrighted by Sony. The Game Boy Advance BIOS is copyrighted by Nintendo. Downloading those files from a website without authorization from Sony or Nintendo infringes their copyright.
Some emulators have created open-source replacement BIOS files written from scratch specifically to avoid using the copyrighted originals. These replacement BIOS files are legal and resolve the infringement issue. The open-source emulator community has produced legal BIOS alternatives for several systems.
Extracting a BIOS file from hardware you own is a grayer area. The DMCA’s anti-circumvention provisions apply if any technological protection measure must be bypassed to extract it. For hardware without such protections, you have a stronger argument that extraction for personal use falls under Section 117, though this has not been definitively settled in court.
- BIOS files from unauthorized download sites: copyright infringement
- Open-source replacement BIOS files: legal
- Extracting BIOS from hardware you own (no copy protection): legally murky, strongest personal use argument
- Extracting BIOS from hardware you own (with copy protection): likely illegal under DMCA
- Consequences of using pirated BIOS: same copyright infringement risk as ROMs
Fair Use and ROMs
Fair use under 17 U.S.C. Section 107 is a legal defense to copyright infringement, but it does not make typical ROM downloading a protected activity. Courts apply a four-factor test to determine fair use, and personal ROM downloading fares poorly under that analysis.
The four fair use factors are: the purpose and character of the use, the nature of the copyrighted work, the amount of the work copied, and the effect on the potential market for the original work.
ROM downloading for personal entertainment purposes fails on multiple factors. The purpose is consumptive rather than transformative. The entire work is copied. And the effect on the market is real because legal platforms exist to sell classic games. Courts have found against fair use in similar situations involving music downloads and film piracy.
Where fair use has applied to ROM-related activities is in specific contexts like reverse engineering for interoperability research, which is what the Sega v. Accolade court found. That is a very different scenario from a gamer downloading Super Mario Bros. to play on their laptop.
| Fair Use Factor | ROM Download Analysis | Assessment |
|---|---|---|
| Purpose and character | Personal entertainment, not transformative | Weighs against fair use |
| Nature of the work | Creative, fictional content | Weighs against fair use |
| Amount copied | Entire work | Weighs strongly against fair use |
| Market effect | Official platforms sell classic games | Weighs against fair use |
Copyright Law and ROMs
US copyright law treats video game ROMs as protected software programs subject to the full scope of copyright protection under Title 17 of the United States Code. Games have been recognized as copyrightable works since the early 1980s.
The Copyright Act protects original works of authorship fixed in any tangible medium, including computer programs. Video games qualify as computer programs and, separately, as audiovisual works. This dual protection means that copying a game ROM potentially infringes multiple distinct copyrights simultaneously, including the code, the music, the artwork, and the audiovisual presentation.
Copyright infringement does not require intent to profit. Reproducing a copyrighted work without authorization is infringement whether you intended to profit from it or gave it away for free. This is important because many ROM downloaders think that non-commercial personal use is automatically protected. It is not.
The copyright term for most classic video games is 95 years from the date of publication for works made for hire, which describes most commercially published games. A game published in 1985 would not enter the public domain until 2080 under current law. Every major retro game library remains fully protected in 2026.
- Copyright protection for games: established since the early 1980s
- Games protected as: computer programs AND audiovisual works
- Copyright term for commercial games: 95 years from publication
- NES-era games entering public domain: not until at least 2076 to 2080
- Commercial purpose required for infringement: no, personal copying still infringes
DMCA and ROMs
The Digital Millennium Copyright Act of 1998 adds a separate layer of legal exposure beyond basic copyright infringement for people who circumvent copy protection to access or copy ROMs.
The DMCA’s anti-circumvention provisions, found at 17 U.S.C. Section 1201, make it illegal to circumvent technological protection measures that control access to copyrighted works. This applies even if the underlying copying would otherwise be permissible. If a game cartridge or disc has any form of copy protection, bypassing it to create a ROM violates Section 1201 regardless of whether you own the physical copy.
The DMCA also makes it illegal to traffic in tools primarily designed to circumvent technological protection measures. ROM ripping devices, mod chips, and similar hardware sold specifically to bypass game copy protection fall into this category.
For individual downloaders who are simply accessing ROM sites, the DMCA’s primary relevance is to the site operators. ROM distribution sites that strip copy protection from commercial games and host the resulting files are engaged in a chain of DMCA violations. That exposure is one reason major ROM sites have been shut down through legal action.
Key Takeaway: The DMCA adds anti-circumvention liability on top of basic copyright infringement, applying to anyone who bypasses copy protection to rip or access ROMs, making the legal exposure broader than copyright law alone.
ROM Sites Legal
ROM sites are not legal under US copyright law. Websites that host and distribute unauthorized copies of copyrighted video games are engaged in copyright infringement at a commercial scale, regardless of whether they charge for downloads.
The Entertainment Software Association and individual publishers like Nintendo have aggressively targeted ROM distribution sites through cease and desist letters, DMCA takedowns, and federal lawsuits. The result has been a long history of major ROM sites shutting down, either voluntarily after receiving legal pressure or involuntarily through court orders.
Major ROM sites that have been shut down or significantly reduced their operations include EmuParadise, which voluntarily removed its ROM library in 2018 after legal pressure, and LoveROMS and LoveRETRO, which were sued directly by Nintendo in 2018. The RomUniverse case in 2021 resulted in a $2.1 million judgment against the site operator.
Operating a ROM site in the US exposes the operator to civil copyright infringement claims, statutory damages, and potentially criminal charges for willful commercial-scale infringement under 17 U.S.C. Section 506.
| ROM Site Action | Year | Outcome |
|---|---|---|
| EmuParadise self-censorship | 2018 | Voluntarily removed ROM library |
| Nintendo v. LoveROMs/LoveRETRO | 2018 | $12 million consent judgment |
| Nintendo v. RomUniverse | 2021 | $2.1 million judgment against operator |
| Various DMCA takedowns | Ongoing | Hundreds of smaller sites removed |
Nintendo ROM Lawsuit
Nintendo has been the most aggressive major publisher in pursuing legal action against ROM sites. Its lawsuits established some of the clearest legal precedents around ROM distribution liability.
The most significant recent case is Nintendo of America v. Matthew Storman, which targeted the RomUniverse website. Nintendo filed suit in 2019, and in 2021 a federal court in California awarded Nintendo $2.1 million in damages after the site operator lost the case. The judgment covered thousands of Nintendo games that were hosted and distributed without authorization.
The 2018 LoveROMs and LoveRETRO case resulted in a $12 million consent judgment, one of the largest ever against a ROM distribution site. Nintendo pursued that case specifically because the sites were generating revenue through advertising while distributing Nintendo’s games without authorization.
Nintendo has also sent cease and desist letters to hundreds of smaller ROM sites and fan projects, resulting in takedowns without formal litigation. The company’s legal team has been consistent in treating ROM distribution as a serious infringement regardless of the site’s commercial model.
- Nintendo v. RomUniverse: $2.1 million judgment (2021)
- Nintendo v. LoveROMs: $12 million consent judgment (2018)
- Nintendo’s stated position: all unauthorized ROM distribution is infringement
- Fan game and ROM hack policy: Nintendo has also targeted some fan projects
- Individual downloader lawsuits by Nintendo: no publicly documented cases to date
ROM Download Penalties
The potential penalties for copyright infringement from ROM downloading range from civil damages to criminal prosecution in cases of willful commercial infringement. The specific exposure depends on the scale and nature of the infringement.
For civil infringement, copyright holders can elect to receive either actual damages or statutory damages. Statutory damages under 17 U.S.C. Section 504 range from $750 to $30,000 per infringed work, with a maximum of $150,000 per work for willful infringement. A person who downloaded a library of 500 games theoretically faces a statutory damages range of $375,000 to $75 million, though courts have discretion to adjust awards.
In practice, individual downloaders have not faced civil lawsuits from game publishers. The enforcement focus has been entirely on ROM site operators. The Recording Industry Association of America’s experience suing individual music downloaders in the early 2000s was widely seen as a public relations disaster, and the gaming industry has generally chosen not to repeat that approach.
Criminal copyright infringement under 17 U.S.C. Section 506 requires willful infringement for commercial advantage or private financial gain. Individual personal-use ROM downloading is unlikely to meet the criminal threshold, but large-scale ROM site operation clearly can.
| Penalty Type | Minimum | Maximum | Notes |
|---|---|---|---|
| Statutory damages (standard) | $750 per work | $30,000 per work | Court has discretion |
| Statutory damages (willful) | $750 per work | $150,000 per work | Requires proof of willfulness |
| Criminal infringement fine | Varies | $250,000 per count | Requires commercial purpose or large scale |
| Criminal imprisonment | N/A | Up to 5 years | For willful commercial infringement |
| Actual damages | Proven loss | Proven loss | Alternative to statutory damages |
Frequently Asked Questions
Is it legal to download ROMs in the US?
No, downloading ROMs is not legal in the US in most circumstances.
ROMs are copyrighted software, and downloading them without authorization from the copyright holder infringes 17 U.S.C. Section 106.
This applies regardless of whether the game is still being sold commercially or whether you own the original physical copy.
The broad availability of ROMs online does not change their legal status.
Is it legal to download a ROM if you own the game?
No, owning the physical game does not make it legal to download a ROM of that game.
Section 117 of the Copyright Act allows making your own archival copy from a copy you own, but it does not authorize downloading a pre-made copy from an unauthorized website.
The backup copy provision requires you to make the copy yourself from your own authorized copy.
Downloading someone else’s copy from a ROM site is infringement regardless of your physical game ownership.
Are emulators themselves legal to use?
Yes, emulator software is legal under US copyright law.
The Ninth Circuit established this in Sony v. Connectix in 2000, ruling that emulator software itself does not infringe copyright.
The legality of the emulator does not extend to the ROMs you run in it, which are judged separately.
Using an emulator with legally obtained content is legal; using it with pirated ROMs is infringement.
What happens if you get caught downloading ROMs?
Individual ROM downloaders have not faced civil lawsuits from game publishers in any publicly documented US cases.
Enforcement has focused entirely on ROM site operators, who have faced judgments ranging from $2.1 million to $12 million in Nintendo cases.
The theoretical civil penalty is $750 to $150,000 per work infringed, but that exposure has not been pursued against individual users.
The legal risk exists and the activity is illegal, but the practical enforcement risk for individual downloaders has been low historically.
Is abandonware actually legal to download?
No, abandonware is not a recognized legal category, and downloading it is not legal.
A game being commercially unavailable or unsupported by its publisher does not affect its copyright status.
Copyright protection continues for the full statutory term regardless of whether the work is actively sold.
No classic video game from the NES, SNES, Genesis, or PlayStation era has entered the public domain as of 2026.
Closing
The law on ROM downloading is clear even if enforcement is inconsistent. Downloading ROMs is copyright infringement under federal law, the “I own the game” defense doesn’t hold up legally, and abandonware is not a real legal concept.
