hacPack GUI is just an interface for CLI. It's just available for Microsoft Windows and it requires .NetFramework 4.5 or higher
Currently, all options are not implemented in GUI and it's recommended to use CLI
hacPackTools are tools aiming for modifying and parsing the files in ncas. make sure to check hacPackTools folder
