There is also Retrotick.

https://retrotick.com/

It simulates x86 (win32 and win16) and implements Windows APIs in javascript and renders window frames with DOM and contents with canvas (e.g. GDI translates to browser canvas operations). A lot of programs run already but a lot of APIs are not yet implemented.

I successfullt spent a few days extending it to run a Click & Create based game from my childhood.

The author actually talks about this in an earlier post[0]
