--- Comment #9 from Toni Spets toni.spets@gmail.com 2008-01-27 01:47:19 --- It doesn't change anything that would make sense. The parameter is not NULL and there is no difference about what the function returns. It just wont work with the game without the relayed function call.
This has something to do with wine's memory management as the patch doesn't really do anything sane?
