// ARCHIVE FOOTER

uint32 {4}   - Crypted offset to start of the DIRECTORY

Notes and Comments

Offset to DIRECTORY must be decrypted before use. Substruct from it:

  • 0 - for demo
  • 0x4857 - for retail/en
  • 0x4858 - for retail/ru

It's easy to detect right value to substruct - first file offset in DIRECTORY always 8.


Other notes:

  • This file format use GZIP compression.
  • Archangel is a game from Poland, so filenames are stored in polish language, e.g. "pieklo_fabryka_wnetrze.scene".
