The Fallout 3 BSA files are the same as used in The Elder Scrolls IV: Oblivion. Preliminary work indicates that they are version 68 rather than version 67.

To open them with BSA Commander (Also see below) you have to do the following:

  • Backup the original .bsa file
  • Open the file in a hex editor
  • Change byte 5 from 68 to 67
  • Save
  • Open in BSA Commander and extract the files

Another way is to use BSAUnpack, telling it to go on when it warns you about archive incompatibility

Fallout BSA UnpackerEdit

A fallout specific unpacker has been released on
