Breath of the Wild modding tools by Rena Kunisaki - ('moc.liamg@rekcahrepyh'):reverse()

Description

A program to extract several file types found in BotW (and maybe other games). Eventually, will be able to repack them too. Designed in such a way that it should hopefully be simple enough to add your own file types.

Usage

Run python botwtools or ./botwtools/__main__.py and follow instructions.

Requirements

Requires Python 3 and modules:

• PyYAML
• sortedcontainers

Acknowledgememts

Uses third-party libraries:

• libyaz0 by MasterVermilli0n / AboodXD
• byml-v2 by leoetlino leo@leolam.fr
• BnTxx by gdkchan
• PNG writing code by Guido U. Draheim

Thanks to leoetlino and KillzXGaming for help reverse engineering file formats.

Bugs/Limitations

• Currently does not support little-endian (WiiU) SARC files.
• Since AAMP only stores the hashes of element names, many elements come out named unknown_xxxxxxxx.
  • I've brute-forced a handful of hashes, but CRC32 is prone to collisions, so some of the names might be nonsense that happens to have the same hash.
• Recursive extraction might be buggy.
• Exported models' textures might not be assigned to the correct UV maps and attributes.
  • In particular, the normal-map textures seem to be missing entirely, and the specular textures are applied to color instead of intensity. These might be Blender bugs because I have no idea.
• This program is only tested on Linux, but probably works fine on Windows too.
• This program only operates on files extracted from the game image. It cannot unpack the .xci image file. Use nxtools for that. I will not help you obtain the game image/files.
