Most of the claimed cases of "recompilation" are just an emulator packaged into the same binary as the game so you can't tell it's an emulator, or are for projects that already had their source code available (in which case "porting" to WASM is trivial because all of the hard work is done by the people who write your-language-to-WASM compilers, and you just need to do a little bit of work to adjust your toolchain to use it). Everyone just takes slopshit at face value and shares clickbait without actually checking any of the work done. It's infuriating how empowering this software is for liars, honestly.
