extracting info from nokia nbf files

Tue May 17 11:42:03 UTC 2016

Hi all,
I've found a few old backups of my Nokia 3230, I'd like to extract
SMSes (I'm not interested in the address book) from the phone, and
therefore I'm searching for a Linux application.
NBUexplorer seems to be corrupted on the sourceforge side, at least
the browser refuses to download it.
Noki does not do the job: it is windows based and it fails extracting
data from my archives, I guess because my SMSes were into folders.
Any other chance?
