How to use the MD2 Exporter?

I’m getting ready to use Irrlicht V0.14 with a C++ game now, I’m having a h*** of a time with Max, so now I want to use Blender for it, but I can’t figure out its MD2 Exporter.

First: What does the top line mean? It just leads me into the Blender directory for my model files with “MD2 file selections” to the side.
Second: “Frame List file to load”? What does that mean?

Also, since it seems to be the script written for Blender 3.33a, does it actually work with the current version? Should I go back to using an older version of Blender for games?

Thanks in advance!
