Also, I should mention that distributing copyrighted content without permission is illegal, so I can't provide direct download links. But I can guide them toward legal sources or how to check availability.

Wait, the user specifically asked for a "create feature." Maybe they want to create a feature for downloading NSP files. Hmm, perhaps they're trying to set up a homebrew app or a way to install NSP files. I need to make sure I'm not endorsing or facilitating piracy. Instead, I should advise them to purchase the game legally or use a digital distribution service that's approved.

But if the user can't find it there, maybe they're looking for a homebrew or mod. In that case, I should inform them about the legal risks and perhaps direct them to community forums where such discussions happen, but not provide direct links.
