I did connect my xbox controller by USB, yes.
You can already play on PC with Edge browser on Windows. I started Zelda on Xbox and continued my save on laptop.
Doesn't work as well on Chrome.
Love that I can play a game on Xbox. Save. Then load up Edge browser on my laptop with my Xbox controller plugged in to continue the save in another room.
Been having the same issue, played the same section in Snes Zelda a few times.
Wasn't aware of the workaround.
Excellent work otherwise though!
