'''Description:''' LEGO Island was written around a very old version of DirectDraw, including a [[Direct3D Retained Mode|retained mode API]] (D3DRM) that is not only unsupported now, it's also been dropped from Windows/DirectX entirely. Many of its DirectDraw function calls are obsolete, deprecated and/or completely abandoned now. | '''Description:''' LEGO Island was written around a very old version of DirectDraw, including a [[Direct3D Retained Mode|retained mode API]] (D3DRM) that is not only unsupported now, it's also been dropped from Windows/DirectX entirely.
