This is a "lite" edition from 1.1 without the immersive hd cinematics as they're over 2Gb.
INSTALLATION:
1- Extract to your Medieval II Total War\mods.
2- Go to the new folder AI_v11_lite in your Medieval II Total War\mods.
3- Use the "Executable" batch file to launch the mod.
4- Play and have fun.
If the game is opened in a small window do this:
Open Configuration.cfg with a text editor (preferably Notepad++) and you see this part:
[video]
movies = 0
windowed = 1 ## Windowed mode (windowed = 1) is usually more stable
borderless_window = 1
no_background_fmv = 1
show_banners = true
# widescreen = 1
# unit_detail = high
# grass_distance = 9000
Change windowed = 1 to windowed = 0
Then in game options chose the native resolution of your monitor, after that you can change to windowed = 1 again and you'll still have full screen.
NOTE:As of now THERE ARE NO REAL TIME BATTLES, on encounter battles are auto-resolved automatically by script.
