It's this one : https://github.com/h1romas4/wasm-genplus
The problem with this is that it supports only joypad and if a frame in the sound department is lost then you loose a frame in the entire game.
I made some small changes to this to have keyboard suport and a little extremely naive change in the sound that gave me worse sound but more stable frame rate.
I had posted my version over the discord
Hope this link works.
