Binkdx8surfacetype-4

In RAD Game Tools' internal API for Bink, surface types are enumerated to tell the game engine where and how to draw the decoded frame. SurfaceType-4 typically corresponds to:

Ensure the target Direct3D surface is created with D3DFMT_A8R8G8B8: Binkdx8surfacetype-4

// DirectX 8 example
g_pd3dDevice->CreateImageSurface(width, height, D3DFMT_A8R8G8B8, &pSurface);

If you've ever dug into the memory snapshots or debug logs of a PC game from the early 2000s, you might have stumbled upon the cryptic string: BinkDX8SurfaceType-4. For most modders, it’s a dead end. For engine programmers, it’s a nod to a simpler—yet tricky—era of DirectX 8 rendering. Binkdx8surfacetype-4
