Using Map Editor and wmLibEditor.
When in Map editor u open the map u want to make a minimap for, and export as a bmp file.
Then u look at the size, in my case
2100 x 1400 then u ?4. But on the First Dimention u add 2.
Example: 2100 ?4 = 525 then u add 2 so its 527.
then u do 1400 ?4 = 350.
So u resize it like that, then u export 1 map from Gadgets image viewer, which will open in paint if u have it set up to open in paint, then u simple paste your map u've resized on top, and save as wat u like.
Then u open wmLibEditor, open mmap, then another window will open showing u wat maps r there, then u click the folder top left to import your bmp file u made in paint, and then u save it, and then it shud work. Worked fine for me.
Also u may have to import some other maps if u get a error when openin mmap.wil. then at the end when u've added some maps, then u copy some of the blank looking boxes, and paste after the maps u've added, which shud stop it coming up with the error next time u open it up.
Pasting the blank boxes dont seem to work, so if you want to add another minimap in after u've saved..... you'll have to imput em all in again then add the one u wanted to add at the end. Still not too bad, just gotta spend alittle more time doing it
