N64Wasm
What it is
N64Wasm is a free browser-based emulator for Nintendo 64 games, built as a WebAssembly port of the RetroArch ParaLLEl Core. The project says a good portion of 3D games can run at full speed on a mid-range computer. It stores save states and SRAM in the browser and supports importing and exporting save files; cloud save states are available when users host their own server. Controls include keyboard and button remapping, multiple controllers, mobile controls, Gameshark codes, and mouse input. Display options include zoom, fullscreen, and dark mode, alongside audio support and a software renderer option. Gamepad support has been tested with Xbox and PS4 controllers. The project also describes a Windows version for debugging that uses Visual Studio 2019 and requires a graphics card supporting OpenGL. Self-hosting is available with a custom ROM list and user-provided ROM files. The MIT-licensed software is provided without warranty. On iOS 16 and later, the demo advises disabling Safari’s GPU Process: WebGL experimental feature to improve framerate.
