To dump Switch games for Ryujinx, you absolutely need a hacked (modded) console to extract your own game cartridges or digital purchases. A completely stock, unmodified Switch cannot read game data in a way that produces usable files for the emulator. If you own only an unmodified retail console, you cannot extract the game files required by Ryujinx, so you might check the ryujinx switch game compatibility list to see which titles run well before you invest in modding hardware. This remains true regardless of whether you legally own the cartridge or digital title.
Why a stock switch cannot dump switch games
A stock Nintendo Switch runs Horizon OS, the system’s proprietary operating system. This OS strictly controls access to game data. When you insert a game cartridge, the system only allows the OS to mount the game’s encrypted partition for execution within the secure environment. It never exposes the raw, decrypted file structure to the user. Similarly, digital games installed on the internal storage or SD card are stored as encrypted NCA (Nintendo Content Archive) files. These files are bound to the hardware’s unique keys. Without those keys, the files are unreadable by any PC software, including Ryujinx. The Switch does not provide a “copy to SD card” option for game data. The USB or wireless transfer protocols it supports explicitly exclude game titles. Even if you could access the SD card’s file system, the encrypted blobs inside the `Nintendo` folder are useless. This is because stock firmware never performs the master key derivation outside of authorized game launches.
What a hacked switch actually does
A hacked Switch replaces or supplements the stock firmware with custom firmware (CFW) like Atmosphere or SX OS. This CFW disables the security checks and allows unsigned code to run. Homebrew tools then interact directly with the game cartridge slot or the installed title database. For a cartridge, a homebrew tool reads the raw ROM dump and packages it into an XCI file. It strips the encryption by using the device’s own keys during extraction. For a digital title, a homebrew tool reads the installed NCA files and decrypts them on the fly, outputting a standard NSP file. This process requires physical access to the hacked Switch and the game you legally own. No remote or cloud-based method exists. After dumping, you transfer the resulting XCI or NSP to your PC via USB or SD card. Ryujinx can then mount or install the file as if it were a real game.
The common misunderstanding about sd card files
Many users insert their stock Switch’s SD card into a PC and see folders like `Nintendo/Contents/registered`. They assume those encrypted files can simply be copied over and used in Ryujinx. This is a critical error. The files inside that directory are encrypted with the unit’s unique key area. Neither Ryujinx nor any PC tool can decrypt them without those keys. The keys are never stored on the SD card. Attempting to load an encrypted NCA directly into Ryujinx results in a “missing keys” or “firmware not found” error. Even if you possess the keys from another source, the files themselves are tied to your specific machine’s ticket and title ID structure. A generic decryption will not produce a playable game. The only way to obtain usable files is to dump them from a hacked Switch. This process outputs already-decrypted XCI or NSP containers. This misunderstanding leads many to waste time searching for a way to “download games on Ryujinx” without realizing the emulator cannot run encrypted dumps. A similar principle applies when you download PS2 games for PCSX2, where you must provide your own BIOS file to stay legal. For Switch emulation, a hacked console remains the only legal route to obtain your own game files.
