Nintendo won a default judgment against James C. Williams, known online as “archbox,” in the U.S. District Court for the Western District of Washington on September 23, 2026. The court awarded Nintendo $4.5 million in statutory copyright damages—$150,000 for each of 30 named games—and issued a permanent injunction targeting unauthorized game distribution and circumvention software.

Because Williams did not answer or defend the lawsuit, this was not a contested trial deciding between competing evidence. The order accepted Nintendo’s showing for default judgment and granted the requested relief.

What Nintendo won

The case, Nintendo of America Inc. v. Williams, concerned allegations that Williams copied and distributed Nintendo Switch games through websites and online communities and supplied or promoted software designed to bypass Nintendo’s security measures.

Item Result
Court U.S. District Court for the Western District of Washington
Decision date September 23, 2026
Procedural posture Default judgment after Williams failed to appear or defend
Copyright damages $4.5 million statutory award
Calculation $150,000 for each of 30 named games
Additional relief Permanent injunction against specified distribution and circumvention activities

The games covered

The order names 30 works. Examples include The Legend of Zelda: Tears of the Kingdom, Mario Kart 8 Deluxe, Super Smash Bros. Ultimate and Animal Crossing: New Horizons.

#1 Best Overall
Nintendo Switch 2 System
  • The next evolution of Nintendo Switch
  • One system, three play modes: TV, Tabletop, and Handheld
  • Larger, vivid, 7.9” LCD touch screen with support for HDR and up to 120 fps
  • Dock that supports 4K when connected to a compatible TV*
  • GameChat** lets you voice chat, share your game screen, and connect via video chat as you play

Why the award was $4.5 million

Copyright law allows statutory damages of up to $150,000 per work for willful infringement. In this default proceeding, the court applied that maximum to all 30 listed games, producing the $4.5 million total.

The figure is not a proven calculation of Nintendo’s actual lost sales. The order says Nintendo had not specifically quantified lost revenue. Instead, Nintendo submitted evidence that thousands of copies were distributed and discussed an approximate $50-per-game value. The court found that the alleged scale and seriousness of the conduct supported the maximum statutory award in this case.

“Williams’ egregious infringement activities merit substantial punishment here.”

Rank #2
Nintendo Switch with Neon Blue and Neon Red Joy-Con - Handheld Gaming Console
  • 6.2” LCD screen
  • Three play modes: TV, tabletop, and handheld
  • Local co-op, online, and local wireless multiplayer
  • Detachable Joy-Con controllers
  • Nintendo Switch is the home of Mario & friends

That sentence appears in Judge Lauren King’s statutory-damages discussion. It describes the court’s assessment for purposes of the default judgment, not a finding reached after a defended trial.

What the permanent injunction prohibits

The injunction reaches Williams and people acting under his direction or control. It bars conduct identified in the order, including:

  • Making the identified pirate shops available.
  • Distributing or promoting circumvention software or technology covered by the order.
  • Distributing unauthorized copies of Nintendo games.
  • Encouraging other people to obtain circumvention software or copy Nintendo games.
  • Keeping relevant shops and distribution platforms operating; the order requires them to be disabled.

The exact scope comes from the injunction’s listed activities. It is not a blanket command covering every possible modification to a Switch.

Does this mean all Nintendo Switch mods are illegal?

No. This judgment addressed alleged piracy, unauthorized game-copy distribution and related circumvention activity. It did not create a general rule that every console modification, homebrew project or user-created game modification is unlawful.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

Whether a particular modification is lawful can depend on what it does, which software or hardware it uses, how copyrighted material is obtained, and what someone distributes or encourages others to do. The Williams order should therefore be read narrowly, according to its piracy and circumvention facts.

Why the default judgment matters

Williams did not respond after being served, and the clerk entered default. The court then evaluated Nintendo’s request for default judgment and permanent injunctive relief. There was no defense presentation or contested trial weighing both sides’ evidence.

Rank #4

Nintendo Switch with Neon Blue and Red Joy-Con (Renewed)
  • This pre-owned product is not Apple certified, but has been professionally inspected, tested and cleaned by Amazon-qualified suppliers.
  • 6.2” LCD screen.
  • Three play modes: TV, tabletop, and handheld
  • Local co-op, online, and local wireless multiplayer
  • Detachable Joy-Con controllers

That procedural history matters when interpreting the result: the $4.5 million award is binding relief against the defendant in this case, but it is not a tested industry-wide price for piracy damages or a ruling on every modding dispute.

Nintendo’s warnings about circumvention products

Nintendo’s consumer legal guidance says circumvention products can bypass security measures. Nintendo also warns that unauthorized products may damage a console, affect warranty coverage, reduce functionality or cause problems after network updates. Those are Nintendo’s stated warnings and legal position; they are not independent findings that the Williams case proved each effect.

How the U.S. case differs from the Netherlands MIG Switch ruling

A separate September 2026 case in the Netherlands involved an online seller offering MIG Switch Cards and MIG Switch Dumpers. The District Court of The Hague ordered that seller to stop offering and selling those devices, according to Nintendo Life’s September 11, 2026 report.

Best Value
Nintendo Switch – Neon Red and Neon Blue Joy-Con (Renewed)
  • One player can use a Joy-Con in each hand
  • Two players can each take one
  • Multiple Joy-Con can be employed by numerous people for a variety of gameplay options (additional Joy-Con sold separately)
  • Slip a set of Joy-Con into a Joy-Con grip accessory, mirroring a more traditional controller. Or, select an optional Nintendo Switch Pro Controller.
U.S. Williams case Netherlands MIG Switch case
Court and territory U.S. District Court for the Western District of Washington District Court of The Hague, Netherlands
Defendant and conduct James C. Williams; alleged facilitation of unauthorized game-copy distribution and circumvention An online seller offering MIG Switch Cards and MIG Switch Dumpers
Procedure Default judgment after the defendant failed to defend Separate Dutch proceeding; not the Williams judgment
Remedy reported $4.5 million in statutory damages plus a permanent injunction Order to stop offering and selling the devices

These cases should not be merged. They involve different defendants, courts, countries, conduct and remedies.

What Switch owners should take from the ruling

  • Do not treat a court headline as proof that every form of modding is prohibited.
  • Recognize that distributing unauthorized game copies and promoting circumvention tools can create serious legal exposure.
  • Distinguish statutory damages from measured lost revenue: the $4.5 million was set by the statutory-per-work framework in a default proceeding.
  • Read Nintendo’s device warnings as the company’s guidance, not as findings automatically applicable to every modified console.

The Bottom Line

Nintendo’s September 23, 2026 victory was a $4.5 million default judgment against James C. Williams, with a permanent injunction aimed at piracy and circumvention activity. It was not a contested trial and does not establish that every Nintendo Switch modification is illegal.
