형들이거 xp에서 왜 그래픽 깨지냐?

[ddraw(123.109)]

겜하는데 창모드 자꾸 키기 귀찮아서 걍 직접 만들었거든?
근데 윈7~윈8에선 존나 잘되는데 xp에선 색상이 32비트로 설정되있으면 위에 사진 처럼 뜨는데 왜이럼?

게임 그래픽은 ddraw 라고 DirectDraw 이용함

CreateSurface 하는 부분 =>

if(ddsd->ddsCaps.dwCaps & DDSCAPS_PRIMARYSURFACE)

                  ExitProcess(0);

      }

      g_pDDS->SetClipper(g_pClipper);

      g_pClipper->SetHWnd(0, ghWnd);

      ddsd->dwFlags = DDSD_WIDTH | DDSD_HEIGHT | DDSD_CAPS | DDSD_PIXELFORMAT;

      if(FAILED(hr))

      {

               ExitProcess(0);

      }

      _lvalue_return = ((_CreateSurface)((int*)Address_CreateSurface))(a1, ddsd, lpDDS, pUnkOuter);

       if(FAILED(_lvalue_return))

      {

               MessageBox(0, L"CreateSurFace 실패 Code : 3", 0, 0);

               ExitProcess(0);

      }

//Blt, fastBlt

}

RGB 565는 게임에서 저걸로 생성하길래 그대로 옵션줌
