In their own words
CEN64
CEN64 is a free Nintendo 64 emulator for Windows, Linux, and macOS. It aims to reproduce the console by modeling its hardware at the register-transfer level, while optimization remains a goal for eventual full-speed play on modest systems. To run a game, users need a valid NTSC or PAL pifdata.bin file and a big-endian .z64 ROM. CEN64 can also run 64DD disk images with a valid 64ddipl.bin file and an .ndd image. The README documents EEP4K, EEP16K, FLASH, and SRAM save options; users select the save type themselves. A multithread option is available and is described as faster than running without it. Prebuilt executables are linked for Windows and Linux, including a Debian 9 x86_64 Linux build. On macOS, the emulator must currently be built from source, using CMake, iconv, OpenAL, and OpenGL. The project uses the BSD-3-Clause license. An open issue reports an ARM build limitation.
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.
