The issue is that Generals uses the pci id of the graphics card to find out 
which capatiblities it has. This is completely broken behavior because there 
are capatiblity flags in Direct3D which the game could read with 
IDirect3D9::GetCaps. Henri reported that Generals is broken in windows too 
when you have a shiny new nvidia card because nvidia changed the number 
scheme and Generals thinks it is running on a really ancient card and 
disables vital rendering.

you can try a virtual desktop: wine explorer.exe /desktop=name foo.exe
or use ksnapshot or gimp or whatever and tell it to make a screenshot after 
waiting some time.

Can you file a bug report with the crash output and a +ddraw log? (Well, when 
the winehq servers are up again. Ah, I just see they are back)

If you file a bug report, it is likely to happen that you won't hear much for 
quite some time. This isn't because we don't care about bug reports, but 
rather that we have a huge number of bug reports. Even with the bugs I know I 
could keep myself busy for months if not years. If you assign the bugs to 
directx->ddraw or directx->d3d8/9 I will find them again at latest when I've 
run out of open bugs and search for new work :-)

Yeah I understand. Similar things got me started with hacking on the wine code 
more than 2 years ago. I wanted Empire Earth to run, fixed 2 bugs in the old 
ddraw code. Then I hit the more fundamental problem of multithreading support 
which also affected d3d8 and d3d9 apps, so I decided to rewrite ddraw over 
wined3d and fix the threading problems there. That was almost a year ago when 
I started the ddraw rewrite by adding '#include "wine/wined3d_interface.h" ' 
in the ddraw code and got approx. 300 errors back :-\

Ironically Empire Earth still doesn't run, but now the more basic work is done 
and I can start with implementing multithreading support for Direct3D. But 
I'm afraid that this won't be enought and this game also needs proper render 
target locking support and a gdi engine...

So appoligies accepted :-)
