These are great news!
I was thinking some time ago why there is no such emulator yet, but in practice I never did search for it.
There are Windows 3.x game packs on internet archive:

I hope that Wine will work on Windows someday, so we will be able to even play old not compatible 32-bit games on newer Windows (yes I know compatibility mode and other tricks but they are not working with any game):
