2 weeks ago However i tried to use the Dd7to9 option and no matter what setting i try this fails with a game specific error that D3DXCreateContextEx No Z Buffer is available.
The released build has limited support for Z Buffer. The latest dev build has better Z Buffer support: dxwrapper.zip
2. DDrawCompat does some funky stuff with the window/message handler function.
It sounds like DDrawCompat overwrites the message handler with the customer launcher. I did not write DDrawCompat and I don't fully understand it all.
3. I tried using ONLY DDrawCompat for the GDI fixes in conjunction with dgvodoo2 as a ddraw wrapper for DX7 - but I don't understand how to achieve this - using RealDllPath=DDraw_DGVodoo.dll and renaming DDraw.dll to DDraw_DGVodoo.dll does not do anything.
I don't think this will work. dgVoodoo2 only handles the DirectDraw/Direct3D calls. However, DDrawCompat does a lot of stuff at the WDDM driver level that is not seen by dgVoodoo2.

I have a DirectX7 Game that mixes ddraw with GDI.
The game with a custom launcher works fine with ONLY the option DDrawCompat enabled, in fact it works so well it fixes most performance issues through the GDI/GetDC / Surface handling which even dgvodoo2 could not fix till today.

Before:
Hook_RegisterClassA lpszClassName _thegamewindowclass
After:
Hook_RegisterClassA lpszClassName DDrawCompatPresentationWindow Hook_RegisterClassA lpszClassName DDrawCompatMessageWindow
I tried to hook into either DDrawCompatPresentationWindow or DDrawCompatMessageWindow but then the loading does not continue. How can i hook into the RegisterClassA function? The original game window still gets created with CreateWindowExA but that doesnt help me, seems like there are 2 more windows that no do the job for the original games window/message handler.
