Official libraries/classes

1. BloodRayne: CPod, CPodFile, CDemonPod

Unofficial utilities

1. PodTools is a powerful utility with support for a variety of Bloodrayne 1/2 formats. Unfortunately, this utility does not take care of checksums and timestamp. The header checksum gets the magic value 84 8E DE 4E and other fields get 0
2. br2poded [mirror]. According to this, the Buka localizer used its own game archives format, making changes to the executable file. Therefore, a special utility has been released for the Russian version of Bloodrayne 2.
3. Abyss' POD Tools somewhere on the web, it is possible to find localized versions of Bloodrayne 1, the archives of which will contain a comment starting with [Abyss' POD Tools]. However, no other evidence of its existence has been found
