Just wondering if this is possible? Google didn't really enlighten me much on working with .bnk's or how data is actually stored in them (I assume its an archive of some type?).

Dunno if this helps

The closest I've found, is an old app for NFS4 to extract and insert sound files into the bnk's used in that game for addon cars or something. Couldn't get it to run under XP though.

Maybe the RAD Video Tools help?

Installed them eariler, but all they allow you to do is play back .bik files, like the intro
