Help to add a simple option to Splash Screen

[Zazamastro]

I think the extension should just wait for a new window to appear before closing.
It should not be able to know what is happening in the emulator.  You could try doing a bat script with nircmd to keep the splashscreen in the foreground.  You can use "bat to exe converter" to not show the window.

Thank you so much for the tip! Unfortunately I don’t know where to start to create a script with nircmd. Everything I found is on this page (https://nircmd.nirsoft.net/script.html), but I don’t even know if that’s what it takes to do what you say... 

However I wonder how it is possible that no one else has thought to ask anything about this (I do not say it in a polemical tone). I mean it’s a standard simple thing in Launchbox / BigBox...
