--- Comment #15 from Daniël Mantione daniel.mantione@freepascal.org 2009-02-25 14:59:58 --- Well, I assume you mean actual Windows truetype files rather than the X11 font mapping Wine does. I made the Winetricks script install all native fonts, so I guess it is with native fonts, but I don't know exactly how I can verify wether Wine was actually using them.
Usp10.dll was of course set to "Builtin (Wine)", otherwise your patch isn't used.
Note that the game comes with some .ttf files as well for part of its font needs.
