## What it is
nxdumptool is a Nintendo Switch homebrew application that generates XCI, NSP, HFS0, ExeFS, RomFS, NCA, certificate, and ticket dumps from gamecards and installed SD/eMMC titles. Written in C on top of libnx, it also supports dumping data directly to a PC over USB and to USB mass storage devices.

## Use cases
- dump nintendo switch gamecards to xci images
- extract nsp dumps from installed switch titles
- dump romfs and exefs from a switch game
- back up switch gamecard data to a pc over usb
- extract tickets and certificates from digital switch titles
- dump individual nca content from a specific title
- copy switch dumps to a usb mass storage drive

## When to choose
- You need full XCI or NSP dumps of physical gamecards or installed digital titles on a hacked Switch.
- You need granular extraction of NCA, RomFS, ExeFS, HFS0, gamecard headers, certificates, or tickets.
- You want to send dump data straight to a PC via the USB ABI or write to FAT/NTFS/EXT USB mass storage devices.

## When to avoid
- You need a polished graphical interface - the active rewrite branch currently lacks a proper UI and ships as proof-of-concept builds.
- You are looking for Switch emulation or gameplay software rather than a dumping/backup tool.
- You need a dumping tool for consoles other than the Nintendo Switch.
