In their own words
n64js
n64js is a free N64 emulator written mostly in pure ES6 JavaScript, with a hosted version on GitHub Pages. It uses WebGL and provides keyboard controls plus a controller-configuration interface. Many ROMs run close to full speed, but graphical problems remain and imprecise cycle counting affects compatibility. Save data can persist through localStorage, with save import and export listed as implemented features. Saving and loading require native Uint8Array base64 methods supported in Chrome or Edge 140+, Firefox 133+, or Safari 18.2+, including iOS. The live site reports Chrome, Firefox, and Safari tested on macOS 13.5; Edge is untested. Low-level audio emulation is implemented, while high-level audio remains in progress. Savestates are listed as a TODO. Debug options include Off, Simple, and Mattias CRT display effects. The MIT-licensed repository also documents Bun scripts for headless emulation and programmatic controller input.
