I need some help extracting a .pak file from the game rush for berlin gold . I’ve tried several methods using tools like QuickBMS, Dragon UnPACKer, and Watto Game Extractor, but none of them have given me any results so far.

Any guidance or suggestions would be greatly appreciated.

Thank you very much. I’m leaving the file in attachment pak+zlib1.dll

Hi Moderators, could you move this to the Game Archives section please.

The "Rush for the bomb" files that we analyzed previously look quite different to these ones, as well as different to the ones we just downloaded from the game demo.

We haven't quite worked out how to read these files properly yet. Most of the file seems to be XOR'd with byte 66, however the filenames in the directory don't work out, so there might be additional encryption on those (or maybe we're wrong about the byte 66). The general archive structure looks to be something like this:

// HEADER
  8 - Unknown
  4 - Header (PACK or RFTB)
  4 - Directory Length

// DIRECTORY
  X - Filename
  1 - null Filename Terminator
  4 - Unknown
  1 - Encryption Flag? (1)
  4 - Unknown

// FILE DATA
  // for each file
    X - File Data

I don't have any reason to believe that ZLib is being used, being that the PAK file is easily compressible, and there is plenty of repeating bytes in the directory and the file data that really should be stripped out if it was already compressed.
