In the dim glow of a gaming forum’s server logs, a curious hexadecimal signature appeared: 0100074010E74000 . To most, it was gibberish. To a Switch modder, it was the title ID for Silver Chains , a first-person horror game.

The user, “CrypticKraken,” had just dumped their own copy of the game. The .nsp (Nintendo Submission Package) file sat at 4.7 GB—too large for free email, too sensitive for public torrents, and too risky for free file hosts that log your IP. They needed to transfer it securely. For free. Most free transfer services—WeTransfer, Mega, Google Drive—offer convenience at the cost of privacy. Files are scanned, links are logged, and downloads are throttled. For a user sharing legally questionable (or region-locked) backups, those terms were a dealbreaker.
