--- Comment #4 from Zebediah Figura z.figura12@gmail.com --- It may also be a different d3dx DLL that this game is trying to use; I'd check a +loaddll log to see which.
In any case, does this error occur with upstream Wine? Or if the game is unplayable (or breaks sooner) with upstream Wine, is it known which Staging patches are necessary for the game to work?
