Hacbuild v1.1 - JulesOnTheRoad's mod

Hacbuild is a utility to rebuild Switch GameCards (XCI) made by LucaFraga

Original version can be found at https://github.com/LucaFraga/hacbuild

This is the revised version made by julesontheroad https://github.com/julesontheroad/hacbuild

Changes

  • Erased need for XCI Header Key
  • Readapted hfs0manager to build hfs0 partitions with hashregions bigger than 0x200
  • Added new functions

Usage

  • xci auto builder: Builds a XCI from a directory containing the folders 'normal', 'secure' and 'update' and a 'game_info.ini' file. hacbuild.exe xci_auto <input_folder> <output_file>
  • xci auto builder with file deletion while building: Same but with input folders and temporal file deletion while building. hacbuild.exe xci_auto_del <input_folder> <output_file>
  • Manual builder for xci from root.hfs0: Builds a XCI from a directory containing 'root.hfs' and 'game_info.ini' hacbuild.exe xci <input_folder> <output_file>
  • root.hfs0 auto builder: Builds a root.hfs0 from a directory containing the folders 'normal', 'secure' and 'update'. hacbuild.exe rhfs0_auto <input_folder>
  • root.hfs0 auto builder with file deletion while building: Same but with input folders and temporal file deletion while building. hacbuild.exe rhfs0_auto_del <input_folder>
  • Manual builder for hfs0 (normal/secure/update): Builds a hfs0 partition hacbuild.exe hfs0 <input_folder> <output_file>
  • Manual builder for root.hfs0: Builds a hfs0 partition, currently it needs a multiplier, needs work to read the multiplier from input hfs0 files. hacbuild.exe root_hfs0 <input_folder> <output_file> <multiplier>
  • Get 'game_info' file named as file input name: Get game_info file named as the input xci in the folder you set. hacbuild.exe read xci <input_file> <output_folder>
  • Get 'game_info' file named as gameinfo.ini: Get game_info file named as gameinfo.ini in the folder you set. hacbuild.exe read xci <input_file> <output_folder>

Functionalities

  • Builds\rebuilds xci files and hfs0 partitions and root.hfs0 files.
  • Rebuilds hfs0 partitions with less padding than the official ones.
  • Reads xci files to obtain game_info files.
  • Can build empty hfs0 partitions.

Limitations

  • The switch don't like secure partition with less than 4 files inside.
  • You can put several content inside the secure partition but you can't put more than 8 different games inside. It may be due to horizon qlauncher, it may be able to read them without error with a custom launcher.
  • Only tickets for updates get read by horizon inside the secure partition.
  • Still need to make code to generate automatically the multiplier when building a root hfs0 from other hfs0 partitions
