Please convert the old binary level files to python so that they can be more easily read, understood, improved and used as the basis for new levels. Right now they are in a binary format that isn't human readable, even after unpacking MacBinary.

PS: I see in another bug that bubbros isn't being maintained any longer. I am willing to continue the minimal maintainance that would be needed.
The Debian "issue" is bogus in my honest opinion, but feel free to contribute a conversion of these files from format A to format B if that makes you happy.
