With hacPack, you can mod your game and repack them into NSP, make custom NCAs and NSPs, remove and add contents to NCAs, etc. There's also a GUI interface for hacPack to make it easy to use for everyone, but CLI is version is recommended. hackpack was entered into the GBAtemp Switch Homebrew Bounty 2018 (Tools and Utilities, 1st place). ==User guide== ===hacPack=== Key features: *Support all types of NCAs (Program, Control, Data, Metadata, PublicData). *Options for creating program nca with/without romfs and logo sections. *Support Application, AddOnContent, SystemData and System Program Metadata NCAs. *Support for creating Metadata nca from ncas and cnmt. *Fully crypto customization, Including Keygeneration, Keyarea encryption key 2, Section encryption. *CLI app, also includes a simple GUI for end-users. *Multi architecture and Multi platform compatibility, Including but not limited to: Windows, Linux, macOS, x86, x86-64, arm-le. Some of the use cases of hacPack: *Creating homebrew and custom NCAs/NSPs. *Merging updates and dlcs NCAs/NSPs into game NCAs/NSPs. *Making NCAs/NSPs from game mods and merging game mods with existing game NCAs/NSPs. *Fully modifying and repacking applications and system NCAs. *Changing titleid, icons and other control parameters of games and dlcs, changing the game loading logos. *Repacking games to work on lower firmwares. *Repacking dlcs to work on lower game versions. *Add translations to game. Also hacPack is now comes with hacPackTools, hacPackTools are tools for viewing and modifying the files inside ncas. ===hacPackTools-NACP=== NACP is a file in control nca that specifies multiple parameters of the game including screenshot permissions, video capture permission, savedata file size and etc... Key features of hacPackTools-NACP: *Viewing the value of NACP parameters. *Creating .nacp.xml from .nacp. *Creating .nacp from .nacp.xml. Some of the use cases of hacPackTools-NACP: *Making xml from nacp so it becomes human readable, modifying it and make nacp again from xml. *Creating nacp for homebrew nsps. *Changing the game data save size. *Changing the games and apps permissions, like allowing screenshot and video capture. *Remove the need of selecting user account when launching a game/app. ===hacBrewPack=== [[hacBrewPack Switch|hacBrewPack]] is a tool for creating homebrew nsps is based on hacPack. It's a simplified version of hacPack which is designed for creating nsps from homebrews fast and easy. First and the only legal hbmenu nsp is built with hacPack and the latest version features hacPackTools-NACP which enables capabilities like videocapture and 0 size save data and no need for user selection. Also all custom nsps from Developers and Scene groups are built with hacPack/hacBrewPack. ===Keys=== You should place your keyset file with "keys.dat" filename in the same folder as hacPack. Alternatively, You can use -k or --keyset option to load your keyset file. Required keys are: {| class="wikitable" ! Key Name||Description |- | header_key||NCA Header Key |- | key_area_key_application_xx||Application key area encryption keys |- | titlekek_xx||Title key encryption key |- |} ===CLI options=== <pre> *nix: ./hacpack [options...] Windows: .\hacpack.exe [options...] Options: General options: -o, --outdir Set output directory -k, --keyset Set keyset filepath, default filepath is ./keys.dat -h, --help Display usage --type Set file type [nca, nsp] --titleid Set titleid NCA required options: --ncatype Set nca type if file type is nca [program, control, manual, data, publicdata, meta] NCA general options: --tempdir Set temp directory filepath, default filepath is ./hacbpack_temp/ --backupdir Set backup directory filepath, default filepath is ./hacbpack_backup/ --keygeneration Set keygeneration for encrypting key area, default keygeneration is 1 --plaintext Skip encrypting sections and set section header block crypto type to plaintext --sdkversion Set SDK version in hex, default SDK version is 000C1100 --keyareakey Set key area key 2 in hex with 16 bytes length --ncasig Set nca signature type [zero, static, random].

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. ===Tools=== hacPackTools are tools aiming for modifying and parsing the files in ncas. make sure to check hacPackTools folder Also check [https://github.com/The-4n/hacPack/tree/master/docs docs] for more info. ==Screenshots== {| style="width: 80%; margin-left:0em;" | https://dlhb.gamebrew.org/switchhomebrews/hacpacknx2.png https://dlhb.gamebrew.org/switchhomebrews/hacpacknx3.png |} ==Changelog== '''v1.36-r2 2019/01/19''' *Fixed a bug cause hacPack-GUI to display an invalid titleid error while titleid is valid.
