Edit Infobox Switch Homebrews: HacBrewPack Switch

Free text:

hacBrewPack is a tool for creating Nintendo Switch NCAs (Nintendo Content Archive) from homebrews and pack them into NSPs (Nintendo Submission Package). ==User guide== ===Keys=== *You should place your keyset file with "keys.dat" filename in the same folder as hacBrewPack. *hacBrewPack tries to load "keys.txt", "keys.ini", "prod.keys" and "~/.switch/prod.keys" files if "keys.dat" doesn't exist. *Alternatively, You can use <code>-k</code> or <code>--keyset</code> 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 |- |} ===Compiling Homebrew=== *You need to compile homebrew with proper Makefile, you can use the one in template folder. *You must use valid lower-case titleid in Makefile and npdm.json. Valid titleid range is: 0x0100000000000000 - 0x0fffffffffffffff. *It's not suggested to use a titleid higher than 0x01ffffffffffffff. *Both titleids in Makefile and npdm.json must be the same. Compiled homebrew must have following files: build\exefs\main build\exefs\main.npdm [TARGET].nacp You must place created 'main' and 'main.npdm' files in exefs folder, you can find them in build/exefs. You must rename created nacp file to 'control.nacp' and place it in control folder. ===Icon=== You should place your icon with "icon_{Language}.dat" file name in control folder, "icon_AmericanEnglish.dat" is the default one if you don't manually edit your nacp. dat files are just renamed jpg files. Check [http://switchbrew.org/index.php/Settings_services#LanguageCode switchbrew] for more info about language names. Your icon file format must be JPEG with 256x256 dimensions. *It's highly recommended to delete unnecessary exif data from your jpeg file (easy way: Open icon with GIMP or Paint, save as bmp, Open it again and save as jpg). *If you see placeholder instead of icon after installing nsp, It's likely due to exif data. *If you have some exif data that horizon os doesn't like (like Camera Brand), Your app may leave in installing state in qlaunch. If you don't put your icon in control folder, you'll see a general icon after installing nsp (this is not recommended). ===Logo=== "logo" folder should contain "NintendoLogo.png" and "StartupMovie.gif". They'll appear when the app is loading. Both files are not licensed according to switchbrew but none of those are included. You can also replace these files with custom ones. You can use <code>--nologo</code> if you don't have any custom logos and you don't have the original ones, as the result switch will show a black screen without nintendo logo at top left and switch animation on bottom right. ===CLI options=== <pre> *nix: ./hacbrewpack [options...] Windows: .\hacbrewpack.exe [options...] Options: -k, --keyset Set keyset filepath, default filepath is ./keys.dat -h, --help Display usage --nspdir Set output nsp directory path, default path is ./hacbrewpack_nsp/ --ncadir Set output nca directory path, default path is ./hacbrewpack_nca/ --tempdir Set temp directory filepath, default filepath is ./hacbrewpack_temp/ --backupdir Set output nsp directory path, default path is ./hacbrewpack_backup/ --exefsdir Set program exefs directory path, default path is ./exefs/ --romfsdir Set program romfs directory path, default path is ./romfs/ --logodir Set program logo directory path, default path is ./logo/ --controldir Set control romfs directory path, default path is ./control/ --htmldocdir Set HtmlDocument romfs directory path --legalinfodir Set LegalInformation romfs directory path --noromfs Skip creating program romfs section --nologo Skip creating program logo section --keygeneration Set keygeneration for encrypting key area keys --keyareakey Set Set key area key 2 in hex with 16 bytes lenght --sdkversion Set SDK version in hex, default SDK version is 000C1100 --plaintext Skip encrypting sections and set section header block crypto type to plaintext --keepncadir Keep NCA directory --nosignncasig2 Skip patching acid public key in npdm and signing nca header with acid public key Overriding options: --titleid Use specified titleid for creating ncas and patch titleid in npdm and nacp --titlename Change title name in nacp for all languages, max size is 512 bytes --titlepublisher Change title publisher in nacp for all languages, max size is 256 bytes --nopatchnacplogo Skip changing logo handeling to auto in NACP </pre> hacBrewPack doesn't need any options to work. if you follow folder structure properly, you can just run the program and it'll make a NSP. Check template folder for default folder structure, Makefile, npdm json and other useful info. ==Changelog== '''v3.05 2019/10/13''' *Added support for keygeneration 8+.
