WasmPSX

What WasmPSX is
WasmPSX is a free PlayStation emulator for personal use that runs in a web browser. Its project page includes a demo with a ROM-selection control, and the player can load a ROM from a URL or a local file. The listed disc-image format is .bin, and the project does not include ROM files. The README also describes embedding the emulator in a website by loading wasmpsx.min.js and adding a wasmpsx-player element for display. A website must serve .wasm files with the application/wasm MIME type; the README provides configuration examples for Apache and Nginx. The repository includes JavaScript and WebAssembly files and an MIT License permitting use, copying, modification, distribution, sublicensing, and sale subject to its conditions. The license provides the software without warranty. The README links to a ZIP download of the source code, but that linked download returned a 410 Gone error when opened. The project describes the emulator for personal use and documents adding it to a website.
