An independent developer has released Mario Kart 64 Online, an online-only version of the 1996 game playable through a web browser. Nintendo issued DMCA takedown notices against four fan-ported PC titles, including Skyward Sword, Super Mario Galaxy, Mario Tennis Fever, and Mario Kart: Double Dash.
Why it matters
The browser version shows how fan projects built with AI coding tools can quickly bring classic games to new platforms, while Nintendo's takedowns show the company is actively enforcing its rights against unlicensed copies. Readers interested in gaming preservation and intellectual property disputes should note the tension between fan creativity and publisher control.
The browser version includes all 16 tracks and four Battle Mode courses from the original game, with a new race starting every 30 seconds. It supports mouse, keyboard, controllers, a leaderboard, and camera and microphone features, while the duration of its availability remains uncertain.
The players
Nintendo
Nintendo is a Japanese video game company that created the Mario franchise and has a long record of enforcing its intellectual property rights against unauthorized fan projects.
Claude
Claude is an AI assistant developed by Anthropic that was used to help create the browser version through vibecoding.
The details
Mario Kart 64 Online runs in Chrome, Firefox, and Internet Explorer and is built from the SpaghettiKart engine decompilation, with the browser version created with help from Claude through vibecoding. Because the browser version distributes an unlicensed copy of the game, it falls within the scope of Nintendo's enforcement efforts.
Timeline
• November 13, 2026: Nintendo issued DMCA takedown notices against four fan-ported PC titles.
Fan Projects
Nintendo's takedown notices against four fan ports follow its long-running pattern of enforcing copyright against unofficial Mario Kart and Super Mario projects. The browser release shows how AI-assisted development is making such ports faster to build and harder to suppress.
Players can access the browser version directly through Chrome, Firefox, or Internet Explorer without installing software. Because Nintendo has issued takedown notices against similar fan ports, the browser version may not remain available for long.
The takeaway
Fan-made game ports are becoming easier to create with AI tools, but publishers continue to enforce copyright, so players should expect unofficial versions of classic games to remain at risk of removal.
