Eduke32 / Duke Nukem 3D - Successful Build with Full 3D Hardware Acceleration and HRP Support

Spent 2 days trying to figure this out but finally found a solution.

For you Duke Nukem 3D fans out there, if you want a working build of eduke32 on the Orange Pi 5 with full 3D hardware acceleration and support for the High-Res Texture Packs (HRP), you will need to use a fork of the eduke32 source code that supports OpenGLES. The latest official sources found at https://dukeworld.com/eduke32/synthesis/latest/
will build correctly but those sources do not contain OpenGLES support. They will only give you software rendering which means no 3D support and no high-res 3D models and textures.

An eduke32 repository that supports OpenGLES with full 3D hardware acceleration can be found here:
https://voidpoint.io/dgurney/eduke32/-/tree/interpolation

If you want to use the HRP packs, you need to unzip the HRP zip file contents into the same folder
where the eduke32 binary is located. Do not put them into the autoload folder.

Now run eduke32. Uncheck the Polymer driver.
Once inside the game, hit the ESC key, select Options->Display Setup->Video Mode->Renderer
and make sure it is set to Polymost. Hit Apply.

Hit ESC again to go back one menu level. Make sure 3D Models is set to Yes.

That's it. Enjoy.

In some areas I'm getting over 270 fps.

Here are a couple screenshots with the HRP enabled. FPS is in the upper right corners of the snapshots.
