Mario Kart 64 Gets Unofficial Online Multiplayer Browser Port

One Of The Most Influential Mario Kart Games Is Now Free In-Browser Published Nov 14, 2026, 7:38 AM EST Sam Woods is TheGamer’s Senior Reporter. He’s been in games journalism since 2020 and has undertaken a variety of roles in that time. These have included roles such as SEO Editor, Managing Editor at DualShockers, and Global Head of Gaming, and he's also been seen on the BBC. He was promoted to the Senior Reporter position in 2025 following a series of high-quality reports and exclusives for TheGamer. Since 2020, Sam has written over 3,000 articles and specializes in telling the stories of the people behind the games. He’s interviewed the biggest game directors, some of the industry’s top talents, told the stories of how indie games came to be, and spoken to players about what really makes them tick. He’s also interviewed some of the world’s biggest musical artists to find out how the medium has inspired their work, and TV and Film actors about their roles in video game adaptations. He even hosted a PAX panel in 2021 and made a documentary in 2024 surrounding the creation of a Disney game. Alongside this, Sam focuses on breaking news. He got the scoop on Perfect Dark’s cancellation, provided context on some AI drama, and revealed that Lady Dimitrescu’s actress would love to step back into the character’s giant shoes. These articles have been picked up by the biggest gaming sites, including IGN, GameSpot, and PC Gamer. He also loves to dive into the numbers behind the games. Sam’s journey in games journalism has taken him all over the world. He’s covered Gamescom in Germany, Summer Game Fest in Los Angeles, and Tokyo Game Show in Japan, each on three occasions. He’s been learning Japanese since 2024 with the intention of identifying and translating Japanese-language news and bringing it to English-language audiences first, something he’s done countless times. Sam’s first review was 2020’s Battletoads reboot, and he’s since reviewed games in The Legend of Zelda, Super Mario, and Pokemon franchises. The Nintendo 64 was era-defining for kart racers. Mario Kart 64, like Mario 64 before it, helped to ease the world-famous plumber into the 3D era, and it was rivaled heavily, maybe even surpassed, by Diddy Kong Racing. I even remember having a great time with Mickey's Speedway USA, Lego Racers, and Micro Machines. PlayStation, of course, tried to get in on the action with Crash Team Racing, but really, only one series has stood the test of time: Mario Kart. It's one of the best-selling franchises in the history of gaming, and Mario Kart 8 Deluxe is Nintendo's second-best-selling game of all time. As more and more games begin to make their way to browsers, unfortunately, with the help of Claude and vibecoding, one player has taken things back to Mario Kart's first 3D outing, creating a web browser version of Mario Kart 64, designed exclusively for online racing. A Multiplayer Version Of Mario Kart 64 Is Available In Chrome, Firefox, And Internet Explorer Mario Kart 64 Online is an online-only version of Mario Kart 64, playable completely through your web browser. It was designed by Oliver Sauter and is based on the SpaghettiKart engine decompilation. It features all 16 tracks from the main game, including fan favorites like Bowser's Castle, Yoshi Valley, and Kalimari Desert, alongside all four Battle Mode courses. It's very well streamlined, with a new race starting every 30 seconds, and it works with a mouse, keyboard, and controllers. It has a leaderboard and even features camera and microphone support. It's not likely to be around for long, though. Nintendo is on the warpath again, targeting fan-ported PC titles. Just yesterday, we reported on how the company had DMCA'd four popular fan ports, including Skyward Sword, Super Mario Galaxy, Mario Tennis Fever, and Mario Kart: Double Dash. Because this Mario Kart 64 port distributes an unlicensed copy of the game, it's a prime target for the litigious company. Vibecoded multiplayer ports are all the rage within gaming at the moment. While they rely heavily on AI for creation, titles like Need for Speed: Underground 2, Halo: Combat Evolved, and SoulCalibur 2 are currently all playable in your browser. It may not be the case for much longer, though. Claude has now been programmed to make things a lot harder for players to slopcode these games, and it has also been told to ignore any prompt containing the word "Pokemon". Clearly, as they should be, these AI companies are scared of game developers, and hopefully we soon move back to the older method of decompilation, with players coming together to decode binary 0s and 1s.
