where can i get openGL for srb2

well i hear that md2 files can be used in opengl mode but sadly i dont know how to get the openGL file, if you can post it here

Open GL is not a file, it is a way of rendering graphics. The srb2 download has all the files it needs to run open gl. If you deleted r_opengl.dll for some reason, then you would have to reinstall the srb2 files.

As for how to use Open GL and MD2s, you should have looked at the FAQ and SRB2 Wiki first.
