Main features
--------------
* Generates full XCI cartridge dumps (with optional certificate removal). All dumps are padded with 0xFF to match the full game card size.
* Generates XCI cartridge dumps (with optional certificate removal and optional 0xFF padding to match the full game card size).
* CRC32 checksum calculation for XCI dumps.
* Precise HFS0 raw partition dumping (using the root HFS0 header from the game card).
* Partition filesystem data dumping.
* Partition filesystem browser (with manual file dump support).

* RSDuck, for their vba-next-switch port. It's UI menu code was taken as a basis for this application.
* Foen, for giving me some pretty good hints about how to use the NCM service.
* Yellows8, for helping me fix a silly bug in my implementation of some NCM service IPC calls.
* Björn Samuelsson, for his public domain CRC32 checksum calculation for C (crc32_fast.c).
* The folks from ReSwitched, for working towards the creation of a good homebrew ecosystem.
Changelog
--------------
**v1.0.3:**
* Made the 0xFF padding feature a configurable option.
* Added CRC32 checksum calculation for XCI dumps.
**v1.0.2:**
* Fixed a silly bug in the file splitting code.
