Just a couple of days after computer science student Erik Roystan Ross released a free recreation of the first level of Nintendo's 1996 Super Mario 64 in Unity, the game's original creator stepped in to put “No” in “N(intend)o.”

Ross, who released his high-definition version of the Bob-Omb Battlefield for play in a browser, or on a computer running Windows, Mac, or Linux, didn't have any intention of selling the game and made it available for free.

Still, Nintendo sent Content Delivery Network (CDN) Cloudflare a complaint under the Digital Millennium Copyright Act (DMCA) this week demanding that the fan recreation be taken down:

The copyrighted work at issue is Nintendo's™ Super Mario 64 video game (US Copyright Reg. No. PA0000788138), including but not limited to the audiovisual work, computer program, music, and fictional character depictions... The website at http://mario64-erik.u85.net/Web.html displays, and allows users to play, an electronic game that makes unauthorized use of copyright-protected features of Nintendo's Super Mario 64 video game. Nintendo requests that CloudFlare, Inc. immediately disable public access to http://mario64-erik.u85.net/Web.html.

Nintendo is famously protective of its copyright, taking issue with "Let's Play" videos posted on YouTube and threatening to shut down live-streamed Super Smash Bros. tournaments.

When it received the game company's DMCA complaint, CloudFlare sent the complaint to the person hosting Ross' game, and the hosting provider took the game down and posted the message that CloudFlare sent.

“I was hosting this work for a good friend who is an avid fan, and built the project from scratch as a tech demo,” the provider added. “As mentioned on the original blog post, and noted in various big name media press below, there is no intention to monetize this, ever.”

Nintendo also sent Ross takedown notices for his downloadable desktop versions of the Bob-Omb Battlefield. "The project is no longer playable, or downloadable in any form," Ross wrote on his website. "I received a copyright infringement notice on both the webplayer as well as the standalone builds. Which is fair enough, really. In light of Nintendo recently making a deal to release some of their IPs on mobile platforms, it’s probably not in their best interests to have a mobile-portable version of Mario 64 sitting around."

Ars contacted Nintendo's lawyers, but they did not immediately respond. CloudFlare said that it had no comment.
