• Partition filesystem browser (with manual file dump support).
• Manual game card certificate dump.
• Free SD card space checks in place.

• Game card Title ID and Control.nacp retrieval support using NCM and NS services.

Thanks to

• MCMrARM, for creating the original application.
• 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.
