Hi

as christian wrote, this was fixed in Hatari 2.1, so you can already use 
hatari 2.1 with the BMP codec ; this will create very big files, but it 
goes beyond 4 GB.
For PNG, this was fixed after Hatari 2.1 was released, so you need the 
latest HG sources.

You can also use the ones here http://antarctica.no/~hatari/latest/ , 
maybe they're compiled with different flags/options that will give 
better result in your case.
