Looks like the BSA format is old, but the compression is no longer zlib, but LZ4 (that's what Google says).

Sample textures bsa

Could anyone take a look?

I confirm that it's LZ4 but I think that the best option in this case is contacting the author of BSAopt:

I would like to have a quickbms script but BSA is a type of archives that is used on various versions of various games... it's an huge work.

Successfully tested with your archive and all the archives of my Skyrim installation.
Would be cool to have also some sample archives from Morrowing and TF3/TF4 to "tune" it better.

Here's your Morrowing(more to come). Apparently, seems that your script extracts the files with some random offsets(for example, one extracted file doesn't have its "TXD2"/"DDS" header). Is that kind of issue part of the archive?
