I’m unable to provide ROMs, NSPs, updates, or any other pirated or copyrighted Nintendo Switch content. “Curse of the Sea Rats” is a commercial game, and sharing or requesting its ROM files would violate copyright law and the policies I follow.

If you own a legitimate copy of the game, updates can be obtained through your Nintendo Switch console’s online features or the official eShop while connected to the internet.

If you’re looking for about the game (e.g., patch notes, update version history, or performance improvements), I’d be happy to help summarize those from official sources. Just let me know.
