melonDS Core Loading Error: WebAssembly Magic Word Mismatch (HTML returned instead of WASM)

User is encountering a 'WebAssembly.instantiate' error when trying to load Nintendo DS games using the melonDS core. The error message is: 'expected magic word 00 61 73 6d, found 3c 21 44 4f'. This indicates the browser is receiving an HTML file (likely a 404 or redirect) instead of the required .wasm file. Research suggests a potential filename mismatch in the assets: 'melondslibretro' vs 'melonds_libretro'. User Details: - Browser: Chrome 147.0.0.0 - Platform: Win32 - System: Nintendo DS - Core: melonDS - Premium: True
