What WasmPSX is
WasmPSX is a free web-based PlayStation emulator described for personal use. Its project page includes a browser demo with a control for choosing a ROM, and the player can load a ROM from a URL or a file. The supported disc-image format is .bin, and ROM files are not included. The project also documents how to embed the player in a website: load wasmpsx.min.js and add a wasmpsx-player element to provide the display. A site must serve .wasm files with the application/wasm MIME type; the README gives Apache and Nginx configuration examples. The repository includes JavaScript and WebAssembly files and is under the MIT License, which permits use, copying, modification, distribution, sublicensing, and sale subject to its conditions. The license provides the software without warranty. The README links to a ZIP of the source code, but that download returned a 410 Gone error when opened.
