The No-CD crack for "The Sims" calls to "IDirectDrawImpl_CreateSurface" (ddls/ddraw.c) which calls to "IDirectDrawImpl_CreateNewSurface". One of these calls passes a abnormal value for DDPixelFormat causing "PixelFormat_DD2WineD3D" (dlls/utils.c) to return "WINED3DFMT_UNKNOWN" (0). "IDirectDrawImpl_CreateNewSurface" returns immediately causing the program to fail by raising an exception. In this case, forcing the "IDirectDrawImpl_CreateNewSurface" function to continue with other pixel format, even a not defined one, avoids the exception and "The Sims" starts. The abnormal value is this:
dwFlags = 0x00000000 dwSize = 32 dwFourCC = 0x00000000 u1 = 0x00000000 u2 = 0x00000000 u3 = 0x00000000 u4 = 0x00000000 u5 = 0x00000000
I do not know what is the expected behaviour in real Windows. The original executable file crashes with other error, but I think that is caused by the anticopy protection.

Is this behavior added by the nocd crack?

Can check the full surface description the game passes? Perhaps there are some settings in there that should implicitly provie a pixel format
