--- Comment #144 from Matteo Beniamino beniamino@tautologica.org --- Yes, the patch changes a single byte from 00 to 01. You can check the md5sum before and after the patch to see if the dll is correctly patched. Maybe I can write a small python script to apply the patch, since I don't think diff/patch are the correct tools to use when working with binary files.
