Notes and Comments

  • filenames are encrypted with a simple key-based algorithm
  • files in the package are encoded using 3 different methods:
    • those starting with the [..] pattern are compressed with the LZW algorithm (but files are not clean at 100%, don't know why), after the pattern is specified also the 32 bits compressed and uncompressed size of the file
    • all the others are encrypted with a simple algorithm
    • some of the above files (seems only those in the INI\DAT folder) have a second encryption, simple as above
