Updated to Version 0.3a - urgent bug fix because I accidentally completely broke the program.

New:
Official Discord support server!
Source code now available!


Well, in honour of Master_Key_01 and Master_Key_02's release, I present to you...
HACToolGUI!

It does everything you need to extract XCI, NCA and RomFS files, support for other formats coming soon.

Features:
Simple to use and easy to understand GUI
Built-in keylist manager (Bring your own keys)
Uses HACTool to extract XCI, NCA and RomFS files
Supports all keys
Choose to dump as plaintext NCA, RomFS or to extract the files to a folder
Tiny filesize; around 120KB decompressed
Portable, no installation required

Dependencies:
Requires the latest release of hactool.exe and all its .dll files in the same directory.
Get it from here.

Spoiler: Screenshots:

Complete v0.3 change list:

• Added PFS0 support! (Used in .nsp)
• Automatically fills in the textboxes with keydata from keys.dat when key manager is opened. (Also added a manual option)
• Drag-and-drop file support added for all extraction types
• Key manager button added to main screen
• Internet access no longer required for use; now you can check for updates by clicking the option
• Remembers last selected NCA extraction option
• Remembers previous directory used
• NCA extraction is disabled unless keys are filled and a key file is present
• Checks for incorrectly formatted keys.dat
• Quotes no longer required in directory names

Coming soon:

• Name change
• The hactool files will not be required, the code will be built into the program
• Key verification
• Key derivation, the usual stuff, but will also generate the master_key, package1_key and various others from a supplied keyblob, provided you have the wrapper key for the specific keyblob and the console-unique SBK and TSEC keys
• Bulk file extraction
• Support for all other hactool formats, including Rights ID-encrypted NCAs and SD card files
• Built-in CDN downloader, provide a private key and cert, then add the Title ID, it will get the latest version of the meta file, decrypt the NCA, read the cnmt, get the NCAID of each file and download the NCA of them from the Atum server (provided you have the keys)
• Various file type extractors (BFSAR, BFRES, BFGRP, SARC, SZS, Yaz0, etc.)
• Background music (optional)
• Themes (optional)
• More easter eggs

any idea where to get the .dll files? i cant seem to find it anywhere

This tool isn’t updated/supported anymore. Either learn how to use hactool (which isn’t even difficult to do) or use HACGUI https://github.com/shadowninja108/HACGUI/releases

Does this tool also work for converted NSPs? As in, an XCI converted to NSP rather than an eShop download.

I don't see why it wouldn't but the original hactool should work just as well if not better.
