Fan-made Smash 64 browser game hosts over 1000 custom
A fan-created browser port of Super Smash Bros 64, Smash.fun, allows users to generate and add custom fighters, resulting in a roster exceeding 1000
A fan-made browser game called Smash.fun features over 1,000 custom fighters, including celebrities like Taylor Swift and Lionel Messi. The project is a web port of the classic Nintendo 64 title Super Smash Bros.
Creator Thomas Dimson revealed the project on X, stating it began with his personal wish to be in the game. "I love Smash 64 but I wish I was in it," he wrote, explaining he subsequently added himself and more than a thousand others.
The site's massive roster enables improbable matchups. It includes figures such as Donald Trump, John Cena, Jesus Christ, Elon Musk, Hideo Kojima, MrBeast, Snoop Dogg, and Dwayne "The Rock" Johnson.
How the custom fighter creation works
Players can generate a fighter by entering a name and uploading a reference photo. The site then builds a low-polygon character model using one of the original game's 12 fighter skeletons.
According to its open-source GitHub page, the process also creates a full set of in-game assets. This includes a character select portrait, a stock icon, a series emblem, and a custom announcer call. The creation is then injected into the game as a complete fighter designed to match the N64 title's visual style.
Requirements and legal disclaimers
Smash.fun does not provide the game itself. To play, users must supply their own legally obtained Super Smash Bros ROM file.
The site states that the ROM and its assets stay entirely on the user's device, with nothing uploaded to its servers. It also clarifies that no Nintendo-owned assets are included in the project's source code or hosted online.
Smash.fun is not affiliated with or endorsed by Nintendo. The company has a history of targeting unofficial Smash projects. In a past response, modders even turned a fake Nintendo cease and desist letter into a playable fighter.
This project is part of a trend of classic games being made playable in browsers through fan efforts. Other examples include Super Monkey Ball and its sequel, as well as a version of Super Mario 64 that can be played directly on YouTube.
