Sequential (multi-session) dumping is available in nxdumptool, and it's automatically triggered if there's not enough space for a whole dump - but there must be at least 1 GiB of free space. Note #2: if you use the latest stable build, you don't need to have enough free space in your SD card for a whole dump. Note #1: if you use a SD card with a FAT32 partition and the game you wish to dump is bigger than 4 GiB, you can dump it in smaller parts, but you must reassemble them afterwards. See Note #3 if you wish to use USB -> PC dumping.
Additionally, this build is capable of generating additional TXT files with information about nxdumptool itself, which can be used when submitting information about a dump. The exact details on how to use these exploits to launch homebrew applications aren't covered in this guide.
Must either be vulnerable to Fusée Gelée or have a firmware version compatible with Caffeine. It's an open-source homebrew application capable of generating NX Card Image (XCI) dumps from Nintendo Switch gamecards.
