MapMod

[Jison]

Andrew: As Xaver said, you can still highlight elevation changes. MapMod is a visual mod only and never tamper with any game functions, scenarios or oob-files. This also means you can continue with your ongoing games without any problems.

The mod apply to the 2D Normal View - other zoom levels keep the original graphic.

And I agree with Xaver on this, the easiest way to try out the mod would be to simply make a copy of the original game folder, make new shortcuts to it and then install the mod to this copy.
If you want to backup your old set by renaming anyway, you can check the MapMod file to see what files it contains - as this can vary depending on the title - and then rename the same files in the original before you install.

Hope this helps a bit.
