GBFRDataTools

Data Tool for Granblue Fantasy: Relink archives (data.i)

Features:

• Extraction
  • Extracting singular files (if you know their paths and their hash matches)
  • All known files
• Modding
  • Adding files marked as external files (which means they can be outside data.X like files in the data folder)
• Conversion of viewb, listb, texb, prfb to or from yaml
  • Note that not all prfb files are supported. More details in research notes.

Release build here.

Research Notes

• Currently, 278470 of 292193 (95.3%) game paths are known.
• It is possible to run the game fully unpacked by removing data.i, however all game files need to be extracted in a data folder - requires the majority of game paths mapped out which is not the case yet.
• data.i among other file formats such as models uses FlatBuffers (Cy's internal handler is named FlatArk). It is fully understood and documented in IndexFile.fbs.
• Data/Archive file #2 is hardcoded not to be read from. It is only used on console versions.
• All .xxxb files are UI declarations with names hashed. Many can be recovered from the internal reflection system (specifically <type>::createAttr::ObjectTypeBuilder::vftable uses), but not all properties are present. Basically every .prfb file will use an unique UI component that needs to be supported. Refer to these files.
