I read something about a "dosbox" to run gluugle play apps on ubuntu touch ?

Assuming you mean Google:
You may be thinking of Anbox. But that is old and no longer maintained. The better option, for those devices that can support it, is called Waydroid.

But how that relates to the subject of this thread is unclear to me. And I think you asked this already. Were those answers not what you were looking for?
