Blender 2.49 minimap?

Ok, so i started a game YEARS ago and after it got a lot of interest I finally got around to trying to finish it. It has been going along very smoothly until I hit a problem… I want a minimap, but since I am stuck on 2.49 (the file will not work with 2.5+) none of the scripts I can find will work. Anyone here have something from a while back that can help me out? All I want is a camera above each level that conveys what it is seeing to a plane in the HUD scene… I tried playing with textures but I couldn’t find an option that would work. Any help appreciated!

If you know a little bit of Python you can do it using Viewports.
