Here is the implementation code to add this feature. This assumes you are compiling a C/C++ based emulator (like Mupen64Plus) to WASM using Emscripten. You need to expose functions to the WASM runtime that handle the serialization of the emulator's memory. Alan Wake 2rune Hot Apr 2026

// 2. Read the size from memory let size = Module.getValue(sizePtr, 'i32'); // 3. Copy data from WASM heap to a JS Array let data = Module.HEAPU8.subarray(bufferPtr, bufferPtr + size); // 4. Create a Blob and trigger download let blob = new Blob([data], { type: 'application/octet-stream' }); let url = URL.createObjectURL(blob); let a = document.createElement('a'); a.href = url; a.download = 'n64_snapshot.state'; // File extension document.body.appendChild(a); a.click(); // 5. Cleanup setTimeout(() => { document.body.removeChild(a); URL.revokeObjectURL(url); Module.ccall('emulator_free_buffer', 'void', ['number'], [bufferPtr]); Module._free(sizePtr); }, 100); console.log("Save state downloaded successfully! Size: " + size + " bytes");
