Hello everyone, I'm new to this forum and this is my first post so If I break any protocol I'm sorry 
I've 2 questions and before asking them I made some research on various post here.
1) I've created a game with 32,700 squares and I'd like to edit the terrain for various reasons but each program I tried ask my to convert my .sav to .mp and with Civ2map I can edit the terrain easily BUT now how can I take this .mp (modified) and re-enter it to the .sav ?
2) I would like to custom my game a little bit with few .gif custom made units that I found on this website, how can I introduce them on the game? is it possible to edit the scientific tree with new advance tech? how can we add propriety to each new unit?
I've tried to find a guide or something BUT without any success.
Thanks for your help
