Is this a new feature request?

Wanted change

Add EmulatorJS subfolder proxy file.

Reason for change

I'm not really any good at how it all works, and I'm not comfortable with guessing and then exposing it to the internet.

So if a sample file could be provided, I'd be super grateful!

Proposed code change

Nope.
