Ok, now its letting me load the image.
These may be a little larger than the actual in game menu size, I use them in APE which automatically makes them the right size in game.
I only use ZOOT to adjust the object height, so I have no idea what happens to them if ZOOT is the program used to create the menu icons.
I use the select tool just inside the black outline, copy, and paste into the individual menu file for APE.
The white pixel at the top left of the menu back is the color APE ignores when creating the menu icon, so if you are making white items, you will need to make the whitest color be 254 red, blue and green so the APE program does not ignore it.
There are four menu backs per terrain, for North East, South East, South West, and North West menu icon views of:
Aquatic
Arctic
Coniferous
Deciduous
Desert
Grassland
Highland
Marine
Rainforest
Savannah
