Consider recommending D3DX from NuGet instead of an old DirectX SDK about d3d8to9

[crosire]

Building d3d8to9 doesn't require the old DX SDK, all the necessary declarations are local in https://github.com/crosire/d3d8to9/blob/main/source/d3dx9.hpp. That's needed to make it possible to build this project with just CMake (with toolchains that do not have Nuget).
So the only requirement is the d3dx9_43.dll at runtime (+ d3dcompiler_43.dll through that). It doesn't really matter to d3d8to9 where that comes from, whether installed through the old DX runtime or by extracting it from the D3DX Nuget package. But I would argue that it's easier for a user to click on a download link for the DX runtime installer, rather than having to go through finding and downloading the Nuget package and extracting its contents (for us that's easy, but same cannot be said about all users).

will this work with Nascar 2003 season?

This is true, but at the very least it's still worth a mention, especially with how DX Runtimes were threatened to be delisted multiple times by now AFAIK.
