In order to extract files from commercial ROMs using hactool, keys are required for decryption. For legal reasons, they will not be listed on this page, but they can be found by entering search queries online such as "nintendo switch keys list" or by dumping keys from your own Nintendo Switch using Lockpick. It may be impossible to rip from games that use newer decryption keys than your list includes using this method.
Extracting files from NCA:
./hactool -x file.nca -k keys.txt --romfsdir=outDirectory
Other methods for ripping
Some capture cards allow for lossless image and audio capture.
Ensure your Switch, capture card and capture software are set to the "Full" RGB range with a resolution of 1920×1080.
Ensure your operating system's recording volume is set to 100% and that you are recording at 16-bit 48kHz. Set the Switch's output mode to stereo.
