Conversion of nba files to zip file format

It looks like that NBA files are just renamed ZIP files, so any utility capable of extracting ZIPs can also extract NBA, which is what will more or less achieve nba to zip conversion. You just need to rename the extension from NBA to ZIP so programs automatically recognize it as archive.
