There is no version that works with 1.7.10 I use rei's minimap most of the time. You need to install it on 1.7.2 :/
There will probably be an update with 1.8 :) Follow ReiFNSK on twitter for updates.

I'm honestly not certain how to install it anymore XD I installed this months and months ago lol It's a miracle I got it to work XD just google "how to install rei's minimap"

 

I believe it works with all versions above 1.7.2 if not all versions of 1.7 in general

 

Yes, ECC currently works with versions 1.7.2-1.7.10

 

Just a heads up, LRP http://ecocitycraft.com/forum/threads/official-ecocitycraft-minimap-mod.107122/

Its even better than reis XD

 

I'd also like to point out that from Sept 1st using Rei's will be illegal, along with all other non official ECC minimaps.
