HiyaCFW-Helper

In order to make things easier for me, and because I don't have Windows, I edited the HiyaCFW Helper Python script by jerbear64 and LmN in order to add a graphical user interface to it.

What it does:

Allows you to browse for your NAND backup, no need to place it at the same folder.
Shows the option to choose the output destination, which should be a (preferably empty) FAT formatted SD card or any other folder.
Downloads the latest HiyaCFW release and decompress it.
Autodetects the console region from the NAND dump, downloads and decrypts its v512 launcher.
Creates the patched 00000002.app and bootloader.nds for the custom firmware.
Uses your platform's twltool (binaries for Linux and MacOS included) to decrypt the NAND.
Extracts the decrypted NAND to the chosen output destination.
Installs the HiyaCFW and the patched files on the chosen output destination.
(Optional) installs the latest release of TWiLightMenu++ on the chosen output destination.

NAND mode:

Clicking on the integrated circuit button will give you a NAND mode, where you can remove the No$GBA footer or add it.

Requirements:

Windows:

None, everything needed is included in the release archive.

Linux:

Python 3.5 or greater with the Tk library (I had to do sudo apt-get install python3-tk -y in my Ubuntu virtual machine, sudo dnf install python3-tkinter in Fedora, sudo pacman -S tk in Arch Linux). You might need to install the Python 3 distutils package also.

macOS:

None, everything needed in included in the release archive.

What it includes:

7za binaries for Windows, Linux and macOS. It's used to decompress the HiyaCFW latest release as @RocketRobz uploaded it as a 7z archive. Compiled from the kornelski's GitHub repo.
twltool binaries for Linux and macOS. Compiled from the WinterMute's GitHub repo. For Windows the twltool included with HiyaCFW is used.
NDS bootloader creator binaries for Linux and macOS (based off devkitPro's ndstool v1.27). Compiled from my GitHub repo. For Windows the ndstool included with HiyaCFW is used.
fatcat binaries for Windows, Linux and mxacOS. Compiled from the Gregwar's GitHub repo.

How to use it:

See the DS-Homebrew Wiki's Installing hiyaCFW page for instructions on how to use this.
