Even if the file is "real," the juice isn't worth the squeeze. You are downloading a .rar file from an unknown source. You have to extract it, hoping it isn't passworded. Then you have to trust that the .nsp inside hasn't been injected with a bricker script (for real hardware) or a crypto miner (for your PC).

The file KB-NSwTcH--BASE--NSP--eShop--Ziperto.rar is to download. It represents the dark side of game preservation – raw piracy. If you care about your security, your wallet (from potential fines/malware damage), and the future of game development, steer clear.
