you can merge Switch games, updates and dlcs into a single file
Nintendo Switch游戏文件（如NSP、XCI）通常经过加密，以防止未经授权的复制和使用。要处理这些文件，NSC_Builder等工具必须拥有对应的。这些关键的加密密钥被集合在一个特定的配置文件中，它就是 keys.txt 。
The keys.txt file is a plain text document containing a list of hexadecimal strings. Each string represents a specific key used by the Switch operating system (Horizon OS) to decrypt games, system updates, and save files. A standard keys file contains entries that look like this: nsc builder keys.txt
Here's a general guide:
The most unusual property: The key file also contains a at byte offset 2048 . Using a XOR key of 0xDEADBEEF , we extracted the plaintext: you can merge Switch games, updates and dlcs
Copyright laws protect encryption keys. Sharing or downloading these keys from third-party websites constitutes digital piracy. The legal and intended method to acquire your keys.txt file is to dump them directly from your own physically owned, unpatched Nintendo Switch console using a homebrew payload called . Step-by-Step Setup Guide
If you try to process a brand-new game and get a decryption error, your keys.txt file is likely outdated. When Nintendo releases major firmware updates, they introduce new "Master Keys" to encrypt newer games. If your keys were dumped while your Switch was on an older firmware, NSC Builder won't be able to open newer titles. Using a XOR key of 0xDEADBEEF , we
Downloading keys.txt or prod.keys from random websites or public GitHub repositories is highly discouraged. These files contain copyrighted Nintendo material, and downloading them from third-party sources violates copyright laws and exposes your computer to potential malware.
If you try to process a newer game (e.g., a title requiring Firmware 17.0) with keys from an older firmware (e.g., 11.0), the builder will fail. To avoid errors, always ensure you are using the dumped from a console running the most recent firmware. Pro-Tip: The Power of Multipack Mode
