As for the NSP link, I couldn't find any information on a legitimate NSP ( Nintendo Switch Package) file link for Ace Combat 7: Skies Unknown Deluxe Edition. It's possible that the game is not available on the Nintendo Switch platform, or it's not available through NSP files.
In Ace Combat 7: Skies Unknown Deluxe Edition, players take on the role of a fighter pilot, engaging in intense dogfights and completing various missions. The game features a rich storyline with a cast of well-developed characters, exploring themes of war, loyalty, and friendship. ace combat 7 skies unknown deluxe edition nsp link
