Popup window for retroarch?

As the title states, I’m hoping there’s a native way to create a popup/modal window with retroarch. Is there any way to trigger this, and if so, is there a way to get the response from that window? Thanks.

I don’t think I understand. What is it you’re trying to accomplish?

Sorry, I’ll attempt to clarify. After a game is played, let’s say a high score is detected… I’d love the ability to popup a window over top of the game to add initials to the highscore list.

Ah, I see. Hmm. I don’t think that’s been done. I’m sure it’s possible somehow, but you would be working from scratch, I think.

Ok, thanks for your reply!
