Court documents show Nintendo prevailed on a default judgment after Williams failed to respond to the complaint.
As part of the injunction, the court ordered Williams to immediately disable access to the online shops he controlled that offered extensive libraries of pirated Nintendo Switch games for download.
Aftermath, a reporting outlet that covered the case, relayed confirmation of the $4.5 million damages award and the injunction requiring the closure of the piracy shops.
In its filing, Nintendo described Williams' activities as large-scale unauthorized distribution of copyrighted games.
Rewriting the court's language into plain reporting terms: the court instructed that Williams must promptly and fully block public access to any online storefronts he operates that have been offering substantial libraries of pirated Nintendo Switch software.
Nintendo identified Williams after tracing online activity to Reddit.
According to the complaint, investigators linked a Reddit account associated with membership in the SwitchPirates subreddit to a Nintendo Account.
That Nintendo Account, the company reported, had previously been used to request hardware repairs, which provided address information that aided identification.
Those investigative steps are included in the public record for the case.
This ruling is part of Nintendo's broader, ongoing efforts to protect its intellectual property and the integrity of its Nintendo Switch ecosystem, including the eShop and related distribution channels.
The company has a history of pursuing litigation and takedown actions against individuals and groups that facilitate piracy of Switch software.
For publishers, developers and platform holders, the case underscores the legal and financial risks tied to large-scale unauthorized distribution of game software.
For Nintendo Switch users and eShop customers, the decision represents another enforcement action aimed at safeguarding the official digital marketplace and the developers whose work is distributed there.
