# Is retro game emulation legal? A plain-English guide

Emulator software is legal in nearly every jurisdiction. ROM distribution is the ambiguous part. Here’s the framework, with citations.

## Emulators themselves are legal

Writing and distributing emulator software is legal in the United States and most of the world. The 2000 Ninth Circuit ruling in Sony v. Connectix found that reverse-engineering Sony’s PlayStation BIOS to build a clean-room emulator (Virtual Game Station) was fair use because it produced a non-infringing transformative work. Subsequent rulings have reinforced this baseline.

## ROMs are the gray area

ROMs are copies of the original cartridge or disc data. Distributing copies of copyrighted ROMs without the rights-holder’s permission is copyright infringement in essentially every jurisdiction with a copyright regime — that includes Nintendo, Sega, Capcom, and Square Enix titles. The "abandonware" defense is not a recognized legal doctrine; copyright runs for 70+ years post-publication in most countries.

There is a narrow personal-archival exemption in some jurisdictions (notably the US 17 U.S.C. § 117 for software, though courts have been skeptical when applied to game cartridges). It generally requires you to own the original physical copy, to make the backup yourself from that copy, and to keep the backup for personal use only. Downloading a ROM you didn’t personally rip — even of a game you own — falls outside that exemption in most readings.

## How browser-emulation sites position themselves

Most browser-based retro game sites — this one included — link to ROMs hosted on public archives such as archive.org, where individual ROM uploads are subject to the archive's takedown policy. We do not host ROMs ourselves. If a rights-holder issues a DMCA notice for a specific title, the upstream archive removes that ROM and our site stops serving it. We maintain a DMCA contact page for rights-holder requests.

## Safer alternatives

- Buy the official re-releases — Nintendo Switch Online, Sega Mega Drive Mini, Atari 50, the Capcom Beat ’Em Up Bundle, etc. cover most of the canonical library.
- Subscribe to a streaming service that licenses retro games (Antstream Arcade, GOG, etc.).
- Develop or play homebrew ROMs that are released under permissive licenses by their authors.

## FAQ

Q: Is downloading a ROM I own legal?
A: There is no clean answer in most jurisdictions. Some legal scholars argue that personal-archival exemptions cover downloading a backup of a game you legally own; rights-holders typically disagree. The safest interpretation is that ripping your own cartridge is fine and downloading from a third party is not.

Q: Will I get sued for playing a ROM in my browser?
A: Realistically, no. Rights-holders pursue distributors, not end users. That said, this is general information, not legal advice — consult a lawyer in your jurisdiction if you need certainty.

Q: What about abandonware?
A: "Abandonware" is not a legal status. A game whose publisher no longer sells it is still copyrighted until the term expires (70+ years post-publication in most jurisdictions).
