%description
D7VK proxies Direct3D 7/6/5/3 to DXVK's D3D9 backend on top of Wine's DirectDraw.

Wine's ddraw.dll must stay in place: copy %{_datadir}/d7vk/x32/ddraw.dll
next to the game executable and set a "native, builtin" override for ddraw.
Only 32-bit: the D3D7-era code uses SSE intrinsics that ARM64EC lacks.
