Hi,
There is this (freeware) game called Dink Smallwood, which I would like to
play and it almost works but not quite:
You walk around in this game in a view from above, but wine does not draw
the floor tiles, which is quite annoying.
So I printed out the debugging-manual and tried to figure out, what's
going on. There are two function calls, which I believe to have identified
as the culprits:
DIB_DirectDraw_Blt
or
DIB_DirectDraw_BltFast
The first function call complains saying that DBLT_ASYNC|DBLT_WAIT is not
supported, but as far as I understand the source code, still everything
should be rendered.
The second function is also called a lot and here I am not so sure, what
happens. Is this function completely implemented? I think it is strange
that the last argument is zero, whenever the game calls it. I read the
specification on the ms-homepage and it does not say that you can call it
with a zero parameter.
I think this debugging is very nice (I think it is nicer than actually
playing the game), but I'm far from understanding everything and so I
would be very gratefull for some help.
Thanks
Klaus
