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.
